Integrirana proizvodnja predstavlja kompromis između gospodarskih i ekoloških zahtjeva, odnosno između konvencionalne i ekološke proizvodnje. Transformacija postojećih starih ekstenzivnih maslinika kroz obnovu s nadosadnjom u poluintenzivne maslinike utemeljene na principima integrirane proizvodnje maslina može biti realna opcija za našu proizvodnu praksu. Međutim, maslinarima su potrebne relevantne infor-macije o ekonomskoj opravdanosti ulaganja u obnovu maslinika, kao i o ekonomskim učincima integrirane proizvodnje maslina.
U tom kontekstu, svrha rada je sastavljanje, analiza i razvoj determinističkog tehnološko-ekonomskog simulacijskog modela integrirane proizvodnje maslina u cilju ocjene ekonomske opravdanosti i financijske izvodljivosti ulaganja u obnovu maslinika te ocjene efikasnosti integrirane proizvodnje maslina.
U radu su primijenjene metoda simulacijskog modeliranja, financijski dio cost-benefit analize, analiza osjetljivosti i ekonomska analiza temeljnih mjerila poslovne uspješnosti: proizvodnosti rada, ekonomičnosti i rentabilnosti.
Analiza investicije pokazuje da je ta investicija ekonomski opravdana i financijski izvodljiva, a vrijednosti temeljnih mjerila poslovne uspješnosti pokazuju da je integri-rana proizvodnja maslina efikasna, pod pretpostavkom postizanja očekivanog uroda i uspješne prodaje maslinovog ulja.
Integrated production represents a compromise between economical and ecological demands, or a compromise between conventional and organic production. Regeneration of traditional olive – groves and their transformation in to semi intensive olive – groves is based on the principles of integrated olive production and could be realistic option in our practise.
However, olive growers need relevant information about economic profitability of their investment in the regeneration of olive groves, and about economic effects of integrated olive production.
In that context, the purpose of the research is the construction, analysis and development of a deterministic technological and economic simulation model of integrated olive production. This model is used to estimate economic profitability and financial feasibility of investment in regeneration of traditional olive – groves and economic efficiency of integrated olive production.
In the course of work the method of simulation modelling, financial part of cost – benefit analysis - sensitivity analysis and economic analysis of basical measure of business success (labour productivity, cost-effectiveness and profitability) were applied.
The investment analysis shows economic profitability and financial feasibility of the investment. The economic analysis shows efficiency of integrated olive production on the assumption of expected yield and successful sale of olive oil.

Obnova starih, zapuštenih i opožarenih maslina (II dio)
Regeneration models for old, neglected and burned olive trees

maslina; oštećena stabla; modeli obnove
olive, tree damages; regeneration models
Vijek ekonomskog korištenja masline je oko 50 godina. Nakon tog razdoblja bilo bi potrebno provesti obnovu stabala. Osim obnove koja se provodi zbog starosti stabala, maslinu je potrebno obnavljati i zbog oštećanja nastalih požarom ili studeni. Postoje tri modela obnove oštećenog stabla: model obnove na panj, model obnove u krošnju i model obnove pojačanom rezidbom. Koji model će se primijeniti ovisi o razlogu zbog kojeg provodimo obnovu i o stupnju oštećenja stabla. Radi neravnoteže između korjenovog sustava i nadzemnog dijela obnovljena stabla imaju intenzivan rast te tako veoma brzo dolaze u produktivnu dob. U starim nasadima masline pri provedbi zahvata obnove potrebno je obaviti nadosadnju drugim sortama i sortama oprašivačima. Za kvalitetnu obnovu potrebno je u obnovljenim nasadima provoditi pojačanu ishranu i redovitu agrotehniku obnovljenih stabala.
Period of economic exploitation of olive-growes is about 50 years. After that period it would be necessary to realise the regeneration of tree. Beside regeneration of old age olive trees it is also necessary to conduct regeneration of trees damaged by fire or cold. There are three models of tree regeneration: regeneration model on trunk, regeneration model of tree top and regeneration model by intensive cutting. The model that should be applied is dependent on reason that caused necessity for regeneration and also dependent on stage of tree damage. Imbalance between root system and above-ground part of plant causes intensive growth of regenerated tree and fast transition to reproductive period. In old olive-growes additional-planting with another cultivars and pollinators is recommended. For quality final regeneration of olive trees intensified application of plant nutrition and regularly agrotechnics is required.

autochthonous olive varieties; olive oil storage; quality; virgin olive oil
Ispravan način čuvanja djevičanskog maslinovog ulja znatno utječe na njegovu kvalitetu. U ovom radu opisane su promjene do kojih dolazi prilikom skladištenja maslinovog ulja. U tom smislu ispitivan je 21 uzorak maslinovih ulja dobiven iz tri najzastupljenije autohtone sorte maslina s područja srednje Dalmacije: Oblice, Levantinke i Lastovke. U uzorcima ulja određeni su osnovni kemijski pokazatelji kvalitete (slobodne masne kiseline, peroksidni broj i specifični koeficijenti apsorpcije u UV području). Od ispitivanih uzoraka, petnaest uzoraka (71,4%) je zadovoljilo kriterije za najvišu kvalitetu (''ekstra djevičansko maslinovo ulje''), dok su preostali bili u kategoriji ''djevičansko maslinovo ulje''.
U drugom dijelu rada provedeno je ispitivanje promjena osnovnih parametara kvalitete tijekom 22-mjesečnog skladištenja ulja u tami: 16 mjeseci u hladnjaku i dodatnih 6 mjeseci na sobnoj temperaturi. Tijekom provedenog skladištenja porast slobodnih masnih kiselina je bio manje intenzivan od porasta peroksidnog broja koji je većinu ispitivanih djevičanskih ulja eliminirao iz kategorije jestivih ulja.
The correct storage of virgin olive oil has a significant influence on its quality. The changes during olive oil storage are described in this work. Olive oil samples from three most common autochthonous varieties from the middle Dalmatia region: Oblica, Levantinka and Lastovka, were investigated. Main chemical quality parameters (free fatty acids, peroxide value and UV - specific absorption coefficients) were determined. Among analysed oils, 15 samples (71,4%) achieved the requirements for highest quality (''extra virgin olive oil''), while the others were in the category of ''virgin olive oil''. In the second part of work, the principal quality parameters changes were investigated during a 22 - month storage period in a dark place: 16 months in the refrigerator and additional 6 months at room temperature. During the storage period the increase of free fatty acids was less intensive than the increase of peroxide value which eliminated analyzed the most of virgin oils from the category of ''eatable oils''.

Maslinova muha Bactrocera (Dacus) oleae Rossi najopasniji je gospodarski štetnik masline. Njena rasprostranjenost i brojnost u maslinicima izravno utječu na kvalitetu i trženje maslinovog ulja. U godinama s visokom populacijom maslinine muhe berba mora započeti ranije, što znatno smanjuje randman ulja. Na području Dubrovačko-neretvanske županije posljednjih se godina intenzivno prati dinamika leta maslinove muhe. Let se prati mirisno-hranidbenim lovkama, tipa McPhail i žutim pločama tipa CTP 3 uz dodatak feromona, amonijskih soli i hidroliziranih bjelančevina.
Rezultati praćenja pokazuju usku povezanost leta maslinove muhe s visinom dnevnih temperatura i relativnom vlagom zraka. Praćenjem dinamike leta utvrđena su «žarišta» maslinove muhe te veća rasprostranjenost u zonama samoniklih formi divlje masline
The olive fruit fly Bactrocera (Cacus) oleae Rossi is the most common economically important pest in olive orchards. The number and spread of the fly in orchards are also of great importance for quality and marketing of olive oil. In seasons with high populations of the olive fruit fly the picking and processing should start earlier which decreases the quantity of oil. In Dubrovacko-neretvanska County the olive fruit fly dynamics was followed. McPhail traps were used and yellow sticky traps CTP 3 with feromon, amonium and carbohydrates.
The results show that the flight of the olive fruit fly is highly dependent of temperature and relative humidity. Following the flight dynamics the centres with high density of the olive fruit fly were detected in zones with lots of wild olive trees.

Katastar maslinika
Register of olive groves
Ante Biško
Zvonimir Savić
Dosadašnje aktivnosti Zavoda za voćarstvo u izradi katastra maslinika usmjerene su na obradu zakonodavstva EU iz područja maslinarstva, a posebno dijelova koji su izravno povezani s pripremom katastra maslinika.
Republika Hrvatska je dobivanjem statusa kandidata za članstvo u EU stekla mogućnost korištenja predpristupnih fondova, ali isto tako preuzela je na sebe i određene obveze. Odlukom Vijeća (EZ-a) 2004/648/EC od 13.09.2004. o načelima, prioritetima i uvjetima sadržanim u Europskome partnerstvu s Hrvatskom pred Republiku Hrvatsku se stavljaju zadaci iz područja poljoprivrede koje treba ispuniti prije ulaska u punopravno članstvo EU.
U skladu s pravnom stečevinom Zajednice uspostavit će se odgovarajući sustav za identificiranje zemljišnih parcela i istovremeno poboljšati prikupljanje i obrada statističkih podataka u poljoprivredi.
Current activities in the Institute for Fruit-growing on completing the register of olive groves are aimed at processing the EU legislation in the sector of olive growing, particularly the sector directly connected with the preparation of the olive groves register.
The Republic of Croatia has, by obtaining the status of a candidate for the EU membership, acquired a possibility of making use of access funds, at the same time accepting certain obligations. By the decision of the Council of Europe of Sept.13, 2005 on principles, priorities and conditions contained in the European partnership with Croatia the Republic of Croatia has tacks in the sector of agriculture which must be fulfilled before obtaining full membership of the EU.
In keeping with the legislature of the Union the relevant system for identification of land plots will be established at he same time improving data collection and processing in agriculture.

Fero-kloroza krušaka na južnim obroncima Zagrebačke gore
Iron chlorosis of the pears in south hill-sides of Zagrebačka gora
Ivo Miljković
kruška; fero-kloroza; karbonatno tlo
pear; iron chlorosis; calcareus soil
Provedena su istraživanja uzroka kloroze krušaka sorti Pastorčica, Jakovka, Gellertova i Viljamovka na podlozi sjemenjaka Pyrus communis u voćnjacima na obroncima Zagrebačke gore (lokaliteti: Šestine, Šestinski kraljevac, Gračani, Pustike i Dolje). Kruške su uzgojene u području humidne klime na antropogeniziranom smeđe karbonatnom tllu koje je razvijeno na podlozi lapora miocenske geološke formacije. Ustanovljeno je da se fero-kloroza javlja zbog poremećaja u primanju željeza na tlu koje sadrži više od 20 do 22% aktivnog vapna, a ima alkalnu reakciju tla s pH od 8,0 do 8,5. Zdrava stabla istih sorti postižu dobru vegetativnu razvijenost na tlu alkalne reakcije s pH od 7,5 do 7,9 i količinu aktivnog vapna od 15 do 18%. Lišće klorotičnih stabala sadržavalo je znatno niže koncentracije Fe ili imalo nepovoljan omjer P/Fe od klorotičnog lišća. Osim toga klorotično lišće je sadržavalo signifikantno više P, K i imalo nepovoljniji omjer K/Ca od zdravog lišća. Koncentracija N, Mg i Mn bila je podjednaka u zdravom i klorotičnom lišću.
The research was carried out on the cause of chlorosis of pears of the varieties Vicar of Wingfield, Jacobs, Beurre Hardy and Williams on rootstock seedling Pyrus communis in the orchards on the hillsides of Zagrebačka gora (localities: Šestine, Šestinski kraljevac, Gračani, Pustike and Dolje). The pears were grown in an area of humid climate on anthropogenised brown calcareus soil developed on marly soil of the Miocene geological formation. It was found that iron chlorosis occurred due to disturbance in getting iron in the soil containing over 20 to 22% of active lime and having alkaline soil reaction with pH from 8.0 to 8.5. Healthy trees of the same varieties achived good vegetative development in the soil of alkaline reaction with pH from 7.5 to 7.9 and the amount of active lime from 15 to 18%. Leaves of the chlorotic trees contained significantly lower Fe concentrations and had unfavourable P/Fe ratio of chlorotic leaves. Besides, chlorotic leaves contained significantly higher P and k and had more unfavourable K/Ca ratio than the healthy leaves. The N, Mg and Mn concenttration was equal in healthy and chlorotic leaves.

Istraživana je mogućnost pospješivanja razvoja lateralnih izbojaka u rasadniku na sadnicama jabuke sorti Jonagold i Golden Delicious. U rasadniku su sadnice, kada su postigle visinu oko 75 cm, podvrgnute sljedećim zahvatima: uklanjanje vršnih nerazvi-jenih listića, uklanjanje vršnih nerazvijenih listića u kombinaciji s tretiranjem s 0,25% Paturylom 10 WSC, tretiranje s 0,25% Paturylom 10 WSC (2 puta u razmaku od 24 dana), tretiranje s 20% Promalinom (GA4+7) dva puta u razmaku od 9 dana. Uklanjanje nerazvijenih listića povoljno je utjecalo na kut grananja, ali nije stimuliralo razgranjavanje sadnica. Tretiranje Paturylom negativno je utjecalo na visinu sadnica, ali je broj lateralnih izbojaka bio veći uz povoljan kut grananja. Uklanjanje nerazvijenih listića u kombinaciji s tretiranjem s Paturylom najpovoljnije se odrazilo na razgranjavanje sadnica. Promalin je povoljno utjecao na razgranjavanje, ali je kut grananja bio nepovoljniji nego u ostalim tretmanima.
The ability of various treatments to induce sylleptic shoot development in nursery trees of the apple ‘Jonagold’ and ‘Golden Delicious’ on rootstock M.9 was investigated. The leader management techniques were: removal of sub-terminal leaves, removal of sub-terminal leaves with application of 0.25% Paturyl 10 WSC, and treatment with 0.25% Paturyl 10 WSC (two times at 24 days interval); application of 20% Promalin (GA4+7) two times in 9 days interval; and control, starting when scion length was 75 cm. Removal of sub-terminal leaves increased total branch length, but did not stimulate the lateral branching. Treatments with Paturyl resulted in the lower tree height, in the higher number of branches, and in the greater branch length. Removal of sub-terminal leaves in combination with Paturyl increased the lateral shoot number more than the treatment with only Paturyl. Promalin increased branching, but had little influence on the total branch length. In addition, Promalin decreased branch crotch angles.

Utjecaj arbuskularno-mikoriznih gljiva roda Glomus na rast i razvoj podloge MrS 2/5 (Prunus cerasifera L.)
Influence of arbuscular mycorrhizal fungi genera Glomus on growth and development of rootstoch MrS 2/5 (Prunus cerasifera L.)
Jasmina Družić Orlić
Zlatko Čmelik
Sulejman Redžepović
U ovom istraživanju proučavan je utjecaj četiriju izolata arbuskularno-mikoriznih gljiva Glomus mossae, G. intraradices, G.coronatum i G. viscosum na rast i razvoj podloge MrS 2/5 (Prunus cerasifera L.). Na osnovi dobivenih rezultata istraživanja možemo ustvrditi kako su svi inokulirani tretmani postigli veće vrijednosti mjerenih parametara u odnosu na kontrolne neinokulirane. To se posebno odnosi na postotak preživljavanja transplantacijskog stresa koji se kod kontrolnih biljaka kretao oko 60 %, dok je kod inokuliranih biljaka bio između 80 i 90 %. G.mossae pokazao se kao najuspješnija kombinacija s odabranom podlogom, no odmah iza njega je bio G.coronatum, tako da u nekim mjerenim parametrima među njima nije bilo statistički opravdane razlike. Najslabije rezultate unutar inokuliranih podloga imale su one tretirane s G. viscosum.
This research studied influence of four arbuscular mycorrhizal fungi isolates of Glomus mossae, G. intraradices, G.coronatum and G. viscosum on growth and development of rootstock MrS 2/5 (Prunus cerasifera L.). Inoculated treatments showed improved plant growth and development in comparison with those uninoculated. This can especially be seen in the survival percentage of transplantation stress, which was 60 % for the control and between 80-90 % for inoculated plants. The most effective symbiotic combination was host rootstock with G.mossae, however G.coronatum was also a succefulss combination and in some investigated parameters there was no significant difference between them. Among inoculated rootstocks those treated with G. viscosum were the least effective.

Istraživanja su obavljena sa sortom jabuke Idared (Malus x domestica Borkh), koja je cijepljena na slabo bujnu podlogu M 9, i uzgajana u gustom sklopu (3000 stabala/ha). U pokusu je bilo pet tretmana (fertirigacija s 45 kg N/ha, 60 kg N/ha, 120 kg N/ha, natapanje bez gnojidbe i kontrola – bez natapanja i uporabe gnojiva), u dvije varijante (tretmani za vrijeme vegetacije: od 1. svibnja do 20. lipnja – varijanta A, i od 1. svibnja do 1. kolovoza – varijanta B). Pokus je trajao sedam godina počevši od druge godine poslije sadnje (1992-1998.). Istraživanjima nije utvrđen konzistentan utjecaj primijenjenih tretmana na dinamiku rodnosti, kumulativan prirod i učinkovitost rodnosti. U svim varijantama pokusa dinamika rodnosti slijedila je sličan trend uz slabo izraženu tendenciju alternativnoj rodnosti, a puna rodnost postignuta je u petoj godini nakon sadnje. Dobiveni rezultati istraživanja potvrđuju da je sorta Idared vrlo prikladna za intenzivan uzgoj u sustavu gustog sklopa.
The trial was conducted in an ‘Idared’/M9 orchard (3000 trees/ha), designed as split-block comprising five treatments (fertigation with 45 kg N/ha, 60 kg N/ha, 120 kg N/ha, irrigation without fertilisers, and control - without irrigation and without fertilisers), and two timing variants (treatments during vegetation period from 1 May to 20 June - variant A, and treatments from 1 May to 1 August – variant B). The treatments began in the second year after planting and lasted seven years (1992-1998). Fertigation with different amounts of nitrogen had no consistent effect on the dynamic of cropping, cumulative yield and regularity of bearing. Tendency to biennial bearing was low, dynamic of yield increasing followed the same trend in all treatments, and full productivity was achieved in the fifth year after planting. This means that ‘Idared’ is a very suitable apple cultivar for growing in the system of high density planting.

Utjecaj folijarne aplikacije nekih hraniva, sa ili bez fertirigacije s dušikom, u uspredbi s klasičnom gnojidbom s dušikom, na vegetativni rast, rodnost, te sadržaj mineralnih elemenata u plodovima, istraživan je sa sortom Golden Delicious, cijepljenom na podlozi M9, tijekom 2000-2002. Istraživanja su obavljena u dva subpokusa: u prvom počevši s dvogodišnjim, a u drugom s trogodišnjim voćkama. U obadva pokusa voćke su uzgajane kao super vreteno (razmak sadnje 3.2 x 0.7m). Rezultati istraživanja ukazuju na veće značenje opterećenja rodom, a relativno mali učinak folijarne gnojidbe na rast, rodnost i sadržaj mineralnih elemenata u plodovima u godinama ulaska u produktivnu dob. Kada su stabla bila prikladno opterećena rodom, sadržaj i odnosi N/Ca, K/Ca i (Mg + K)/Ca bili su u granicama koje omogućuju uspješno čuvanje u hladnjači. Nasuprot tomu, u stabala s niskim opterećenjem, niti primjena folijarne gnojidbe nije pridonijela poboljšanju sadržaja mineralnih elmenata i plodovi su bili neprikladni za duže čuvanje u hladnjači.
The effect of foliar application of some nutrients and fertigation in comparison with broadcast nitrogen fertilization on growth, yield and mineral fruit composition of young apple ‘Golden Delicious’, grafted on M9 rootstock was investigated in years 2000-2002. Two orchard experiments were established, one with 2-year and the other with 3-year old trees, grown at a spacing of 3.2 x 0.7 m and trained to super spindle. The results showed low beneficial effect of applied treatments, and relatively high effect of crop load on growth, yield and fruit mineral content. Ratios of N/Ca, K/Ca and (Mg + K)/Ca in fruits indicated good storage quality as related to normal crop load. Contrary to that, when treatments were applied on trees with inadequate crop load, no beneficial effect occurred and fruits showed low storage life. This result illustrates the important balance between vegetative growth and fruit load that occurs during tree establishment.

Wastewaters from the olive-oil extraction process: disposal or valorization?
Otpadne vode iz procesa ekstrahiranja maslinovog ulja: uklanjanje ili valoriziranje?
F. Federici

Olive vegetation waters (OVW) represent a serious environmental problem for the solution of which several disposal methods have been proposed, such as, e.g., physico-chemical treatments (decantation with lime and/or total oxidation; concen-tration, drying and incineration; ultrafiltration and reverse osmosys), agronomic (acquaculture; land-spreading) and animal-breeding methods (direct utilization as animal feed or after protein enrichment by, e.g, yeast or fungal fermentation) and of the "biotechnological" type (fermentation; biological treatments). The OVW might also be a possible resource due to the presence of value products (e.g., antioxidants) and of simple and complex sugars which make the waste a possible basis medium for fermentation processes. This work presents a brief survey of studies conducted at the Departimento di Agrobiologia e Agrochimica, University of Tuscia, on the possible chemical and biotechnological valorization of the OVW. Technical feasibility of various fermentative processes either to obtain products of high added value (polysaccharides and enzymes such as lipase, laccase, Mn-peroxidase and pectinase) or to improve the waste’s agronomic use has been assessed.
Main residues of the olive-oil extraction process are vegetation waters (OVW) and husks. Extraction system, pressure and centrifugation play an important role in the amount and characteristics of both olive oil and residues (Amirante et al., 1993).
In the traditional centrifugation system, 50-100 l of water are added to 100kg of olive paste to reduce viscosity and to improve oil separation: as a consequence, large amounts of OVW are produced. During the last ten/twenty years, new centrifugation systems have been developed that require either less (10-20 l) or no water at all added during oil separation (Fig. 1). In either case, however, residues of the olive-oil extraction may represent a serious environmental problem.
After recovery of residual oil by solvent extraction, husks from traditional processes can find valid utilization as animal feed or as alternative fuel and in compost preparation. OVW, with washing waters, make the oil-mill waste waters (black waters) generally characterized by large volume and high polluting load. Moreover, compounds with biostatic activity (e.g., polyphenols) are largely present.
Vegetacijske vode masline (OVW) predstavljaju ozbiljan okolišni problem za čije se rješenje predlaže nekoliko metoda uklanjanja kao što su npr. fizikalno-kemijski postupci (uklanjanje vapnom i/ili potpuna oksidacija, koncentriranje, sušenje i spaljivanje, ultra filtriranje i obrnuta osmoza), agronomske (akvakultura, rasprostra-njenje po zemlji) te metode u uzgoju životinja (direktna uporaba kao krmiva za životinje ili nakon obogaćenja npr. kvascem ili gljivičnom fermentacijom) i biotehnološki oblik (fermentacija, biološko tretiranje). OVW je također mogući resurs zbog dragocjenih sastojaka (npr. antioksidanata) te jednostavnih i složenih šećera koji čine ovaj otpad mogućim osnovnim sredstvom za procese fermentacije. Ovaj rad daje kratak pregled istraživanja na Bipartimento di Agrobiologia e Agrochimica Sveučilišta Tuscia moguće kemijske i biotehnološke valorizacije OVW-a. Procjenjuje se tehnička izvedivost raznih fermentacijskih procesa za dobivanje proizvoda visoke dodane vrijednosti (polisaharidi i enzimi kao što su lipaza, lakaza, Mn-peroksidaza i pektinaza) ili za poboljšanje agronomske iskoristivosti otpada.
Glavni talozi u procesu ekstrahiranja maslinovog ulja su vegetativne vode (OVW) i ljuska. Sustav ekstrahiranja, pritisak i centrifugiranje igraju važnu ulogu u količini i značajkama maslinovog ulja i taloga (Amirante et al., 1993).
U tradicionalnom sustavu centrifugiranja dodaje se 50 do 100 l vode na 100 kg pulpe maslina da se smanji viskoznost i poboljša separacija ulja pa se kao posljedica stvaraju velike količine OVW. U zadnjih deset/dvadeset godina razvijeni su novi sustavi centrifugiranja koji zahtijevaju manje vode (10 - 20 1) ili uopće ne trebaju vodu za vrijeme separacije ulja (Sl. l). U oba slučaja, međutim, ekstrak¬cije maslinovog ulja mogu predstavljati ozbiljan okolišni problem. Nakon vađenja preostalog ulja izlučivanjem pomoću otapala, ljuske se u tradicionalnom procesu mogu korisno upotrijebiti kao hrana za životinje ili kao alternativno gorivo, te u spremanju komposta. OVW, što za ispiranja čine otpadne vode u mlinu za masline /crna voda/ općenito obilježavaju veliki volumen i visoki teret onečišćenja. Osim toga, velikim su dijelom prisutni spojevi biostatične aktivnosti (npr. polifenoli).

Characterization of extra virgin olive oils obtained from different cultivars
Opis svojstava ekstra djevičanskog maslinovog ulja dobivenog iz raznih kultivara

ekstra djevičansko maslinovo ulje; kultivar
The determination of some minor components of extra virgin olive oil, and in particular of the polyphenolic fraction of pigments and fragrances, can contribute to the characterization of the monovarietal productions: the quali-quantitative assessment of these substances can in fact contribute to the valorisation of typicalities and, at the same time, consent to the optimisation of the operational techniques during the processing and the eventual blending.
The analytical techniques, applied here for the characterisation of extra virgin olive oil of Abruzzo and Istria, have highlighted that chemical composition can enhance the valorisation of these typical products. Nevertheless, further sampling program is needed to evidence typical composition profile that might be used as “origin markers”.
Određivarije nekih manjih komponenata ekstra djevičanskog maslinovog ulja, naročito polifenolne frakcije pigmemta i mirisa, može doprinijeti svojstvima monovarijetetnih proizvoda: kvalitativna i kvalitativna procjena tih supstancija može zapravo doprinijeti valorizaciji tipičnosti te, istodobno omogućiti optimizaciju operativnih tehnika za vrijeme prerade i miješanja.
Analitičke tehnike, ovdje primijenjene za opis svojstava ekstra djevičanskog maslinovog ulja iz Abruzza i Istre pokazuju da kemijski sastav može popraviti vrijednost ovih tipičnih proizvoda. Ipak, potreban je dodatni program uzorkovanja da se dokaže tipični profil sas¬tava, što se može upotrijebiti kao "oznaka podrijetla".

Genetic improvement of olive
Genetsko oplemenjivanje masline
E. Rugini
Patricia Gutiérrez Pesce
genetic improvement; olive
genetsko oplemenjivanje; maslina
In the last decade significant progress has been made in developing successful olive cloning techniques, although some difficulties still remain such as that with establishing sterile cultures in vitro and morphogenesis from mature tissue of cultivars. More work is required, although significant advances have also been made in shoot regeneration from petioles of in vitro grown shoots of several cultivars (Mencuccini and Rugini, 1993). However, the regeneration ability is still low for use in biotechnological applications. The novel strategy of the «double regeneration», developed to achieve somatic embryos in olive cv. Canino and Moraiolo may also be applicable in other cultivars. This technique can be generalised since at present it is essential for inducing and maintaining shoot morphogenic callus in other species such as cherry, apple, and pear (Gutiérrez Pesce et al., 1998; Rugini e Muganu 1998; Abdollahi et al., 2005).
Gene transfer techniques offer a more powerful strategy for genetic improvement in respect to traditional breeding methods. It allows the introduction into one genotype, one or a few pieces of genetic information without drastic modifications of the general characteristics of the plant. Transformation techniques have been developed, by using somatic embryogenesis, and transgenic plants, with some desirable agronomic traits, have already been generated in one cultivar. At present field trials, approved by the Italian Health Minister, are conducted on transgenic rolABC, and osmotin plants.
From transgenic olive plants, similar to kiwi transgenic plants with rolABC genes we expect plants with large root systems, compact vegetative habitus, smaller number of flowers per plant, and high rooting ability of cuttings. In plants over-expressing osmotin gene, we expect a higher tolerance to some fungi. Many genes have already been isolated from several species, which may be introduced in olive singly or associated with others. Transformation experiments with multiple genes (chitinase + osmotin + PR1) are in progress in our laboratory in order to increase fungal resistance.
Antibacterial genes (thionin, cecropin, attacin, etc.) against Pseudomonas syringae and genes for modifying the pattern of fruit ripening (ethylene, PG) are only a few examples of the potential of genetic manipulation to improve olive. A high content of di-hydroxiphenols could confer the valuable bitter taste in the olive oil.
Agrobacterium-mediated gene transfer seems to be the most efficient method in olive.
The molecular techniques should not aim only to make clear the phylogenesis of the genus, but also to clone useful genes and promoters in olive. To facilitate this work, biotechnology, long-term breeding programs and biochemical research should be closely linked to achieve the objectives quickly.
U zadnjem desetljeću učinjen je znatan napredak u razvijanju uspješnih metoda kloniranja maslina iako će neke poteškoće ostati, kao utvrđivanje sterilnih kultura in vitro i morfogeneza iz zrelog tkiva kultivara. Potrebno je još raditi, makar je učinjen znatan napredak i u regeneraciji izbojaka iz petiola uzgojenih in vitro od nekoliko kultivara (Mencuccini i Rugini, 1993). Međutim, mogućnost regeneracije još je uvijek mala za biotehnološku primjenu. Nova strategija "dvostruke regeneracije", razvijena kako bi se dobili somatski embriji masline cv. Ganino i Moraiolo mogu se primijeniti i u drugim kultivarima. Ova se tehnika može generalizirati jer je danas bitna za induciranje i održavanje morfogenskog kalusa izbojka u drugim vrstama kao što su trešnja, jabuka i kruška (Gutierrez Pesce et al. 1998; Rugini e Muganu, 1998; Abdollahi et al., 2005).
Tehnike transfera gena pružaju snažniju strategiju za genetsko oplemenjivanje u odnosu na tradicionalne uzgojne metode. One omogućuju uvođenje u jedan genotip jedne ili više genetskih informacija bez drastičnih modifikacija općih značajki biljke. Razvijene su tehnike transformacije primjenom somatske embriogeneze i transgenske biljke određenih poželjnih agronomskih svojstava i već su proizvedene u jednom kultivaru. Upravo se provode pokusi na terenu, koje je odobrio talijanski Ministar zdravstva, na transgenskim rolABC i osmotinskim biljkama.
Od transgenskih biljaka masline, slično transgenskim biljkama kivija s genima rolABC, očekujemo biljke velikog sustava korijena, zbijenog vegetativnog habitusa, manjeg broja cvjetova po biljci i velike sposobnosti sadnica za ukorijenjenjem. U biljaka preizraženog osmotinskog gena očekujemo veću tolerantnost na neke gljive/gljivice. Izolirani su već mnogi geni iz nekoliko vrsta, što se mogu introducirati pojedinačno ili zajedno s drugima. Pokusi transformacije s mnogostrukim genima (chitinase + osmotin + PRL) su u tijeku u našem laboratoriju, kako bi se povećala otpornost na gljivice.
Antibakterijski geni (tionin, cecropin, atacin itd.) protiv Pseudomonas syringae i geni za modificiranje uzorka zriobe voća (etilen, PG) samo su neki primjeri potencijala genetske manipulacije za oplemenjivanje masline. Visok sadržaj dihidroksifenola mogao bi prenijeti dragocjen gorki okus maslinovog ulja. Prijenos gena posredstvom agro-bakterija čini se najdjelotvornijom metodom u masline.
Cilj molekularnih tehnika ne bi trebao biti samo razjašnjenje filogeneze gena nego i kloniranje korisnih gena i stimulatora u maslini. Da bi se taj posao olakšao potrebno je usko povezati biotehnologiju, dugoročne uzgojne programe i biokemijska istraživanja radi brzog postizanja ciljeva.

Istraživana je dinamika rasta mladice, ploda i biogenih elemenata tijekom razdoblja vegetacije u lišću na četiri godine starim stablima maslina sorti Leccino i Picholine. Masline su uzgojene na crvenici u masliniku Červar kraj Poreča. Istraživanjima je ustanovljeno da rast mladice slijedi izduženu sigmoidnu krivulju. Intenzivan rast mladice odvija se do kraja kolovoza a potpuno završava krajem rujna. Obje sorte postigle su dobar prosječan prirast jednogodišnjih izbojaka. Rast ploda slijedi dvostruku izduženu sigmoidnu krivulju. Najveći je i jednoličan u prvoj i drugoj fazi rasta do 15 rujna kada postigne 50% od volumena u vrijeme dozrelosti. Od 1. do 15. listopada rast je usporen kada dolazi do odrvenjavanja endokarpa, nakon čega je opet intenzivan i jednoličan. Vjerojatno jednoličnom rastu ploda u vrijeme najvećeg nakupljanja ulja, pored ostalog, treba pripisati visoku kvalitetu maslinova ulja u Istri. Naime, uz takav rast postupno se u plodu nakupljaju hranjiva, a posebice ulje i njegovi sastojci. Dinamika biogenih elemenata pokazuje da se koncentracija dušika i kalcija od početka do kraja vegetacije postupno povećava dok koncentracija kalija opada. Koncentracija fosfora, magnezija i bora u lišću obiju sorti je jednolična tijekom vegetacije. Opskrbljenost dušikom, fosforom, kalijem, kalcijem i borom je dobra a magnezijem slaba do umjerena.
Research on the growth dynamics of shoots, fruit and mineral elements in leaves during vegetation was carried out on four year old olive trees of the Leccino and Picholine varieties. The trees were grown in red soil in the olive grove Červar near Poreč. It was established that the shoot growth followed an elongated sigmoidal curve. The intensive shoot growth continued to the end of August and comp¬letely finished at the end of September. Both varieties achieved good average growth of one year old shoots. The fruit growth followed a double elongated sigmoidal curve. It was the biggest and uniform in the first and second phase of growth until September 15, when 50% of the mature volume was achieved. From October 1 to 15 the growth slowed down when the endocarp lignified after which the growth was intensive and uniform. The high quality of olive oil in Istria should probably, among others, be attributed to uniform fruit growth in the time of most intensive oil accumulation. With such growth nutrients, particularly oil and its ingredients, gradually accumulate in the fruit. The dynamics of mineral elements shows that the concentration of nitrogen and calcium gradually increases from the beginning to the end of vegetation while that of potassium falls. The concentration of phosphorus, magnesium and boron in the leaves of both varieties is uniform, during vegetation. The supply of nitrogen, phosphorus, potassium, calcium and boron is good while that of magnesium is poor to moderate.

olives; integrated plant protection; integrated olives production
Integrirana zaštita predstavlja ekološki povoljniju zaštitu bilja koja na prvo mjesto stavlja nepesticidne mjere zaštite kao što su biotehničke, biološke i na kraju kemijske mjere zaštite. Danas se koristi pojam integrirana proizvodnja koja obuhvaća sve agrotehničke mjere u proizvodnji pojedinih poljoprivrednih kultura. U radu je dat prikaz mogućnosti primjene integrirane zaštite masline u integriranoj proizvodnji.
Integrated plant protection is ecologically safe plant protection using in the first place non-pesticide methods such as bio technical and biological but also chemical protective measures. Today the term integrated production is used and it includes all agro-technical measures in agricultural production. Possibilities for integrated olive protection in the integrated olives production are given in this article.

Istraživanja su obavljena sa sortom jabuke Golden Delicious (Malus x domestica Borkh), koja je cijepljena na slabo bujnu podlogu M 9, i uzgajana u gustom sklopu (3000 stabala/ha). U pokusu je istraživan utjecaj fertirigacije dušikom u dozama od 45, 60 i 120 kg/ha, natapanja bez gnojidbe, te kontrole (bez natapanja i uporabe gnojiva) na rast i rodnost jabuke Golden Delicious. Tretmani su primjenjivani u dva vremenska intervala tijekom vegetacije: od 1. svibnja do 20. lipnja, te od 1. svibnja do 1. kolovoza. Pokus je trajao osam godina počevši od druge godine poslije sadnje (1992-1999.). Istraživanjima nije utvrđen konzistentan utjecaj primijenjenih tretmana na dinamiku rodnosti, kumulativni prirod i učinkovitost rodnosti. Najveći kumulativni prirod, uz relativno nizak indeks alternativne rodnosti, postignut je uz fertirigaciju sa 60 kg N/ha, kada je ona primjenjivana u razdoblju od 1. svibnja do 20. lipnja. U svim varijantama pokusa dinamika rodnosti slijedila je sličan trend uz jače izraženu tendenciju alternativne rodnosti u varijantama bez fertirigacije s dušikom, a puna rodnost postignuta je u petoj godini nakon sadnje.
The study was conducted in a ‘Golden Delicious’/M9 orchard (3000 trees/ha) to investigate the effects of fertigation with N at 45, 60 and 120 kg/ha, and irrigation without fertilizers on the growth and productivity of the crop. Treatment durations were from 1 May to 20 June, and from 1 May to 1 August. Treatments began during the 2nd year after planting, and lasted eight years (1992-1999). Fertigation with N at different rates showed no consistent effect on the dynamic of cropping, cumulative yield and yield efficiency. The tendency to biennial bearing in the treatment with N-fertigation was generally low and markedly higher in the treatment without fertigation. The highest cumulative yield, with low index of alternate bearing was obtained in the treatment receiving 60 kg N/ha from 1 May to 20 June. The yield was obtained increasing dynamic followed the similar trend in all treatments, and full productivity was achieved in the fifth year after planting.

Vrijeme uzimanja reznica masline ima značajnog utjecaja na proces rizogeneze. S ciljem utvrđivanja utjecaja vremena uzimanja reznica provedeno je istraživanje u kojem smo varirali tri roka uzimanja reznica: mjesec srpanj, kolovoz i rujan i tri domaće sorte Levantinku, Drobnicu i Istarsku bjelicu. Rezultati istraživanja pokazuju da je najbolji uspjeh ukorjenjivanja postignut s reznicama uzetim u rujnu, a najslabiji u srpnju. Nije bilo statistički značajnih razlika u broju i duljini korjenčića između različitih vremena uzimanja reznica iako je najveća vrijednost zabilježena u rujnu.
The process of rhisogenesis is highly dependent on appropriate time sampling of olive cuttings. With the aim of determining the most convenient time for olive cutting sampling in the rooting process, an experiment with three domestic olive cultivars: Levantinka, Drobnica and Istarska bjelica, was conducted . Their cuttings were collected and put to root during July, August and Semptember. The best rooting results were obtained with the cuttings collected during Semptember, but poor results were obtained with cuttings taken in July. There was no significant differences in the root number and length developed from cuttings collected in different time period, although the highest value was obtained in Semptember.

Temeljna svrha rada bila je analizirati osnovna proizvodna i ekonomska obilježja maslinarstva u obiteljskim poljoprivrednim gospodarstvima kao nositeljima maslinarske proizvodnje, kako bi se dobio uvid u njihov gospodarski položaj i razvojne perspektive. U radu su korištene sljedeće metode: anketa, standardne metode deskriptivne statistike i SWOT analiza. Anketiranje je provedeno na području Dalmacije gdje je smješteno oko 80% proizvodno–preradbenih kapaciteta hrvatskog maslinarstva. Anketirana obiteljska poljoprivredna gospodarstva u prosjeku imaju 121 stablo masline, najčešće na 3 odvojene parcele s dominacijom ekstenzivnog načina uzgoja, dok je gospodarski položaj većine maslinara relativno povoljan. Rezultati SWOT analize pokazuju da strateške razvojne aktivnosti treba usmjeriti tako da maksimalno iskoriste povećano zanimanje za podizanje i obnovu maslinika kao i povoljne uvjete potpore i financiranja, kako bi se umanjila dominacija ekstenzivnog načina uzgoja s velikim kolebanjem priroda i uvozna ovisnost te izbjegle prijetnje globalnog institucionalnog i tržišnog pritiska.
The major aim of the study was to analyse the basic production and economic characteristics of olive production on family farms, so as to get an insight into their economic situation and development perspectives. The following methods were used in the study: survey, standard methods of descriptive statistics and the SWOT analysis. A survey was conducted in the area of Dalmatia where there are 80% of production and processing capacities of Croatian olive production. The family farms surveyed have 121 olive trees on average, usually in three (3) separate lots, using predominantly extensive cultivation method. Most of the olive growers’ economic situation is relatively satisfactory. The results of the SWOT analysis show that the strategic development activities should attempt to make the most of the increased interest in olive groves establishment and regeneration, along with the more favourable terms of support and funding to decrease the prevalent domination of the extensive method of olive cultivation in respect to the yield oscillation and dependence on imports, avoiding threats of the global institutionalization and market pressures.

Sadržaj ulja u plodu masline najvažniji je čimbenik koji određuje ekonomsku vrijednost pojedine sorte i jedan od kriterija za određivanje stupnja zrelosti ploda, odnosno karakterizaciju sorte. Određena je količina ulja u plodu vodećih autohtonih sorti maslina u Istri, tijekom 2004. i 2005. godine, pomoću Soxtec aparata. Dobiveni podaci u zasebnim godinama upućuju na povezanost sadržaja ulja sa sortom, no njihova varijabilnost između dvije godine za pojedinu sortu ukazuje na značajan utjecaj vanjskih čimbenika. Dobiveni rezultati variraju između 21 i 48% ulja u odnosu na suhu tvar ploda, što ukazuje na značajan ekonomski potencijal ovih sorti.
The oil content in an olive fruit is the most relevant factor determining the economic value of singular variety and one of the criteria for fruit maturity degree determination, and variety characterization as well. In this paper, the olive oil content in fruits of leading autochthonous olive varieties in Istria during crop seasons 2004 and 2005, using Soxtec apparatus, was determined. The results obtained reflect mostly the influence of the variety genetic potential on the oil content, when monitored in a single year, but its variation between the two years in a single variety shows the influence of external factors. The oil content on a dry weight basis in fruits of investigated varieties ranged from 21% to 48% which shows their high economic potential.

Maslinovo ulje danas je postalo sinonim zdravog načina prehrane i modernog življe-nja. Sve je više znanstvenih istraživanja i spoznaja o kvalitetnom ekstra djevičanskom maslinovom ulju, tako da i obični potrošač postaje svjestan važnosti njegove visoke kakvoće. Mediteranski način prehrane prelazi okvire mediteranskog bazena i postaje posebno popularan u zemljama srednje Europe, sjeverne i južne Amerike, Kanade, Australije, Novog Zelanda, Japana i Tajlanda gdje se provode velike promocije o važnosti kakvoće maslinovog ulja i njegovom konzumiranju. U ovom radu opisano je značenje masti i ulja u prehrani čovjeka, s posebnim naglaskom na maslinovom ulju, njegovim osnovnim značajkama i utjecaju na zdravlje čovjeka. Na kraju je opisan mediteranski način prehrane s prikazom piramide mediteranske dijete koja svoju popularnost doživljava tek posljednjih 10 godina.
Today olive oil has become a synonym for healthy diet and modern living. There are more and more scientific investigations and knowledge on the quality of extra virgin olive oil, so even common consumers become aware of its importance. Mediterranean diet has crossed the borders of the Mediterranean basin becoming particularly popular in the countries of middle Europe, north and south America, Canada, Australia, New Zeeland, Japan and Thailand, where great promotion campaigns on olive oil quality importance and its consumption are going on. In this paper, the significance of fats and oils in human diet is described, with special accent on olive oil, its' principal characteristics and influence on human health. At the end, the Mediterranean diet is described, with the Mediterranean diet pyramid that has become populari in the last 10 years.

Europsko i svjetsko tržište prehrambenih proizvoda zasićeno je novim proizvodima koji međusobno konkuriraju kakvoćom i cijenom. Nespecifični proizvodi nisu u mogućnosti nositi se s oštrom konkurencijom sličnih proizvoda, a potrošači su često nesigurni u kakvoću onoga što kupuju. Zbog toga se javila potreba za zaštitom proizvoda visoke kakvoće i specifičnih karakteristika. U tu svrhu EU je 1992. godine stvorila sustave: PDO (Protected Designation of Origin odnosno Oznaka izvornosti), PGI (Protected Geographical Indication odnosno Oznaka zemljopisnog podrijetla) i TSG (Traditional Speciality Guaranteed odnosno Oznaka „tradicionalni ugled“). Od 2005. godine proizvođačima u Hrvatskoj omogućena je ista zaštita za proizvode koje imaju i proizvođači u zemljama EU, čime se podiže razina konkurentnosti domaće proizvodnje i prepoznatljivost domaćih proizvoda. Cilj ovog rada bio je pojasniti mogućnosti zaštite maslinovog ulja i stolnih maslina, te iznošenjem praktičnih primjera dati doprinos u bržem integriranju Hrvatske u europsko i svjetsko tržište proizvoda od maslina.
European and world market of foodstuffs is glutted with new products competing by quality and price. Non specific products are not able to deal with a sharp competition among similar products, and consumers are often uncertain about the quality of purchased goods. Therefore the EU created in 1992 three types of food quality system: PDO (Protected Designation of Origin), PGI (Protected Geographical Indication) and TSG (Traditional Speciality Guaranteed). From 2005 Croatian producers have the same possibility of protecting their products as the EU producers, raising the competitiveness and identity of domestic production and products. The aim of the present paper was to clarify the possibilities for olive oil and table oil protection, as well as to give a contribution to faster integration of Croatia in to European and world olive products market by giving practical examples.

Istraživan je utjecaj folijarne primjene dušika, kalija i bora na razinu i dinamiku koncentracije dušika, kalija i bora u listu masline sorte Oblica. Koncentracija dušika u lišću je bila najveća u zimsko-proljetnom razdoblju, a najniža sredinom vegetacije u vrijeme otvrdnjavanja koštice ploda. Koncentracija kalija u lišću se povećavala postupno do razdoblja dozrijevanja plodova. Koncentracija bora u lišću masline nije očitovala pravilnost promjena tijekom vegetacijske sezone. Folijarna primjena N, K i B očitovala se značajnim povećanjem koncentracija dušika, kalija i bora u lišću masline.
Influence of foliar nutrition with nitrogen, potassium and boron in comparison with untreated control trees on the level and seasonal changes of nitrogen, potassium and boron in the olive leaves cv. Oblica were observed over the growing season. The concentration of N in the leaf was the highest in the winter-springtime period, while the lowest N concentration was observed in the middle of the vegetation when stone in the fruit was hardening. Leaf potassium concentration gradually rose up to time of fruit ripening. Boron concentration showed no clear seasonal tendency. Foliar application of N, K and B caused significantly higher leaf N,K and B concentration.

Prirodni procesi spontanog križanja i mutacije kao i selekcija koju su provodili maslinari tijekom dugog razdoblja uzgoja masline rezultirali su velikom raznolikošću morfoloških svojstava. Dodatni problem u kvalitetnoj identifikaciji sorta stvara veliki broj sinonima i homonima koji se koriste u različitim i istim uzgojnim područjima. S ciljem utvrđivanja raznolikosti unutar sorte Oblica započeli smo istraživanje u tri tipična uzgojna područja hrvatske (Konavle, Dalmatinska zagora i Kvarner). Primjenom morfoloških metoda identifikacije utvrdili smo značajne razlike svih istraživanih svojstava između uzgojnih područja kao i unutar pojedinih uzgojnih područja.
The processes of natural hybridisation and mutations as well as selections done by olive tree growers in the long time of olive cultivation resulted in the significant morphological differences of the same cultivar. A big problem in quality cultivar identification are numerous synonyms and homonyms of the same cultivar in different growing areas. With the aim of finding internal variety of olive cultivar Oblica we start with investigations in three typical olive growing area in Croatia (Konavle Dalmatinska Zagora and Kvarner). According to morphological parameters samples of Oblica olive from different places significantly differed, and even in the same growing area.

Zahvaljujući klimatskim uvjetima i zemljopisnom položaju, Hrvatska flora je bogata biljnim vrstama. Među njima postoji velik broj samoniklih voćnih vrsta, zanimljivih zbog natprosječne kakvoće svojih plodova. Podaci iz postojeće literature kao i oni vlastitih istraživanja uspoređeni su s popisom svojti rasprostranjenih u Europi. Zbog jednostavnog međuvrsnog križanja svojti roda Rubus, postoji velika genetska raznolikost unutar roda koja je u prošlosti korištena za izravni odabir iz prirodnih populacija i stvaranje brojnih sorti. Neke od tih vrsta mogu se rabiti i u budućim oplemenjivačkim programima.
Thanks to its climatic conditions and geographic location, Croatian flora is rich in plant species. Among existing plants there is a distinct number of autochthonous edible fruit species interesting for their outstanding fruit quality.
Data from existing Croatian literature and data from our own investigations were compared with the list of Rubus spp. plant taxa that grow in Europe. Easy interspecific hybridization of Rubus species is responsible for high genetic variety of Rubus spp., which was in the past used for direct selection in natural populations and breeding of various cultivars all over the world. It could also be used in future fruit breeding programmes, practically without limitations.

Prunus avium L.; sweet cherry rootstock; cherry fruit cracking
Provedeno je istraživanje oborinama uzrokovanog pucanja plodova trešnje (Prunus avium L.) na lokaciji Jazbina, na području grada Zagreba u 2006 godini. Cilj rada bio je utvrditi utjecaj sorte i podloge na ovo fiziološko oštećenje plodova. Dobiveni rezultati pokazali su da se sorte trešanja međusobno značajno razlikuju u pucanju plodova, a sorte ranijeg dozrijevanja pokazale su znatno veću osjetljivost od onih kasnijih. Sorta Techlovan pokazala je opravdano najveću, a sorte Sam, Kordia, Karina, Oktavia, Hedelfingen i Regina opravdano najmanju osjetljivost na pucanje plodova. Isto tako, promatran je i utjecaj različitih podloga na pucanje plodova sorte Lapins, a dobiveni su rezultati pokazali da podloge imaju značajan utjecaj na pucanje plodova trešanja. Sorta Lapins pokazala je najveću osjetljivost na pucanje plodova na podlozi Pi-Ku 4.20, a najmanju na podlozi F 12/1.
Research on rain - induced sweet cherry fruit cracking was carried out at the location Jazbina, Zagreb, in the year 2006. The aim of the research was to determine the effect of cultivar and rootstock on this physiological disorder of fruits. The results showed significant differences among sweet cherry cultivars to cracking susceptibility, and that the early ripening cultivars had higher cracking susceptibility than late ripening cultivars. Techlovan cultivar showed the highest, while Sam Kordia, Karina, Oktavia, Hedelfingen and Regina cultivars, the lowest cracking susceptibility. We also observed sweet cherry rootstock influence on cracking susceptibility of Lapins cultivar, and the results showed that rootstocks had a significant influence on sweet cherry cracking susceptibility. Cultivar Lapins showed the highest cracking susceptibility when grown on Pi-Ku 4.20 rootstock, and the lowest cracking susceptibility when grown on F 12/1 rootstock.

Ukupne fenolne tvari u sortnim istarskim maslinovim uljima
Total phenols in varietal olive oils from Istria

Olive varieties; agro-ecologic conditions; varietal olive oil; phenolic compounds
Maslina je jedna od onih biljaka o čijoj kultivaciji postoje arheološki dokazi i zapisi sa samih početaka civilizacije na području Bliskog istoka i Mediterana. Razlog tome je skromnost ove biljke, koja može uspijevati i na škrtim tlima u uvjetima suše, a od nje se mogu koristiti lisna masa, drvo, plodovi i ulje dobiveno iz njih. U današnje vrijeme popularnost maslinovog ulja je veća nego ikada prije, što se može zahvaliti suvremenim spoznajama o njegovoj prehrambenoj vrijednosti i pozitivnom učinku na ljudsko zdravlje.
Danas je uzgoj masline većinom komercijaliziran, pa se provode brojna istraživanja u cilju dobivanja što većih prinosa, ali i što kvalitetnijih i prepoznatljivih proizvoda. U ovom istraživanju proučavao se utjecaj sorte i proizvodnog područja (klimatskih prilika) na udio ukupnih fenolnih tvari u uljima tri sorte masline (Istarska Bjelica, Buža i Leccino). U odnosu na druge dvije sorte ulja dobivena od plodova Bjelice općenito imaju veći udio fenolnih tvari. Osim toga, u sušnoj godini ulja svih sorti imala su nekoliko puta veće udjele fenolnih tvari nego u kišnoj godini.
Olive is one of those plants on whose cultivation exist numerous archaeological evidence and written notes from the very beginning of the Near East and Mediterranean civilisations. The reason for this is a modesty of the plant, which could grow on poor soils in dry climates. Besides, the foliage, wood, fruits and their oil can be used. At the present time the popularity of olive oil is higher than ever before thanks to modern knowledge on its nutritional value and beneficial influence on human health. Olive growing is nowadays mostly commercialized, and numerous investigations are conducted with the aim of obtaining high as possible yields, but also to create even better and more recognizable products. In this research influence of variety and production area (climatic conditions) on the total phenol content of oils of three varieties (Istarska Bjelica, Buža and Leccino) has been investigated. In relation to other varieties oils obtained from the variety Bjelica generally had higher phenolic compounds content. Besides, in the dry year oils of all varieties had a few-fold higher total phenolic compounds contents than oils in rainy year.

Provedena su usporedna istraživanja kemijskog sastava i senzornih svojstva šljivovica proizvedenih klasičnim postupkom destilacije od masulja šljive kultivara Elena prevrelog uz epifitnu mikrofloru i uz dodatak selekcioniranog kvasca. Analizirane su koncentracije alkohola, metanola, viših alkohola, ukupnih hlapivih estera, etil-acetata, etil-laktata, acetaldehida i ukupna kiselost destilata i rakija. Među usporednim rakijama utvrđene su značajne (p<0,01) razlike u koncentracijama viših alkohola. Provedenim senzornim ocjenjivanjem višu je ocjenu za ukupnu kakvoću dobila šljivovica proizvedena od masulja prevrelog uz dodani selekcionirani kvasac.
The study on comparison of the chemical composition and sensory properties of plum brandies derived by classical procedure from crushed plum fruits cv Elena (Prunus domestica) fermented by indigenous yeasts and by the addition of selected yeasts was carried out. The samples of crude distillates and brandies were analyzed for alcohol, methanol, total acidity, total volatile esters, ethyl acetate, ethyl lactate, acetaldehyde, and higher alcohols content. Significant differences (P<0.01) in the concentration of the higher alcohols between compared spirits were established. According to sensory analyses brandy derived from crushed plum fruits fermented by the addition of selected yeasts was better evaluated.

Jabučni ocat je prehrambeni proizvod vrlo velike nutritivne i dijetetske vrijednosti. Najbolja sirovina za njegovu proizvodnju je zdrav i sočan plod sorata jabuke sa većim sadržajem šećera.
Proizvodnja jabučnog octa sve je češća na poljoprivrednim gospodarstvima u Republici Hrvatskoj. U posljednje vrijeme proizvodnja jabuka se povećava, a time i ukupna količina prerađevina. Cilj ovog istraživanja je određivanje kakvoće prirodnog octa od jabuka sorti Idared, Gloster, Golden Delicious i Jonagold. Istraživanja su provedena u razdoblju od veljače do rujna 2005. godine. Tijekom istraživanja praćena je octena fermentacija jabučnih vina uz određivanje ukupne kiselosti i vrijednosti pH. U octu s većim udjelom sorata Golden Delicious, Gloster i Jonagold utvrđene su veće količine octene kiseline. Sorta Idared pogodna je za proizvodnju octa samo uz dodatak ostalih sorata, jer sama ne postiže trgovačku jačinu octa.
Apple vinegar is an agricultural and alimentary product. It has great nutritious and dietetic value. The best raw material for its production is healthy apple fruit of adequate cultivars that contain a greater amount of sugar and dry matter. Better raw material allows the production of a better final product.
The production of apple vinegar is more and more popular on farms all over Croatia; a big quantity of apple vinegar is used in everyday life, as well as other apple products and derivates. The research aimed at defining the quality of vinegars produced from 4 apple cultivars (Idared, Gloster, Golden Delicious and Jonagold) on 6 samples with different cultivar proportions. The research was performed in the period from February to September 2005.
The fermentation was monitored during the research. After the fermentation, pH-level and acid quantity were measured in the samples. The results showed that the samples of vinegar with a greater amount of cultivars Golden Delicious, Gloster and Jonagold gained a greater quantity of acids. The cultivar Idared gains a smaller quantity of acids and for that reason it is recommended for vinegar production only in cases when other apple cultivars are added to help the formation of acceptable acid amount.

Tijekom provođenja monitoringa štetnika mediteranskih kultura u sklopu programa Izvještajno prognoznih poslova, utvrđena je nazočnost karantenskog štetnika s liste A1 karantenskih štetočinja, naziva Rhagoletis cingulata Loew. (Diptera: TEPHRITIDAE). Sjeverno-američka trešnjina muha – R. cingulata Loew, utvrđena je ulovom odraslih muha u lovkama tipa McPhail, uz dodatak hranidbenog atraktanta u miješanom nasadu voćnih vrsta. na lokalitetu Split. S obzirom da je vrsta R. cingulata štetnik koji napada plodove više vrsta roda Prunus, a među njima višnju – P. cerasus, trešnju – P. avium i rašeljku – P. mahaleb, postoje ozbiljne mogućnosti udomaćenja i širenja na cijelom području Dalmacije.
While monitoring the mediterranean crop pests, as a part of the national reporting and early warning system, the presence of new quarantine pests from the A1 list of the quarantine pests - Rhagoletis cingulata Loew. (Diptera: TEPHRITIDAE) was confirmed. North-American cherry fruit fly – R. cingulata Loew. was confirmed by trapping adults in McPhail trap type with food attractant, in a mixed fruit orchard, at a location of Split. Since the R.cingulata is a pest attacking fruits of several Prunus types, among them sour cherry - P.cerasus, sweet cherry – P.avium and mahaleb cherry – P.mahaleb, there are serious possibilities for its domestication and spreading on the area of Dalmatia.

Istraživanja utjecaja opterećenja rodom na generativnu aktivnost, te kakvoću plodova, obavljena su tijekom 1998-1999. godine sa sortom ‘Golden Delicious’, cijepljenom na podlozi M9. Voćke su bile posađene u proljeće 1997. godine na razmaku 3,0 x 0,8 m (4166 stabala/ha) i uzgajane kao super vreteno. Na osnovi lipanjskog otpadanja plodića u 1998. godini voćke u pokusu smo podijelili u tri skupine: s niskim (A), srednjim (B) i visokim (C) početnim rodnim potencijalom. U 1998. godini voćke u skupini A opterećene su s 5, u skupini B s 15, te u skupini C s 25 plodova na stablo. U 1999. godini unutar svake skupine bila su tri opterećenja: 40, 60 i 80 plodova/stablo (nisko, srednje i visoko opterećenje). Rezultati dobiveni tijekom dvogodišnjeg istraživanja ukazuju na značajan utjecaj opterećenja rodom na prirod i kakvoću plodova. Najbolji rezultati glede priroda i kakvoće plodova ostvareni su kod svih pokusnih skupina (A, B i C) uz umjereno opterećenje rodom. Stoga se u intenzivnom uzgoju jabuke moraju prikladno opteretiti rodom, a posebice u razdoblju ulaska u punu rodnost.
Investigations into the effect of crop load on yield and fruit quality of young apple ‘Golden Delicious’, grafted on M9 rootstock was conducted in years 1998-1999. The orchard was planted in the spring 1997, at a spacing of 3.0 x 0.8 m (4166 trees/ha) and trained to super spindle. On the basis of the rate of natural fruit drop in the second growing year, three experimental groups were established, classified as trees of low (A), medium (B) and high initial productivity (C). In that year crop load was regulated by hand thinning in group A to 5, in group B to 15 and in group C to 25 fruits/tree. In the third growing year crop load was regulated to three levels (low, medium and high) equally in all groups (40, 60 and 80 fruits/tree). The results showed significant effect of crop load on yield and fruit quality. The best results were obtained in all groups when crop load was medium. This result illustrates the importance of regulating fruit load in the intensive apple orchards, particularly during tree establishment.

The thinning response was studied on six years old trees of ‘Gala’/M.9. The treatments of single application of ethephon 200 ppm at the balloon stage, of naphthaleneacetic acid (NAA) 10 ppm or benzyladenine (BA) 100 ppm at 10 mm fruit diameter as well as the sequential treatments of ethephon followed by NAA or/and BA and tank mixed NAA + BA treatment were performed. A non significant thinning was obtained in treatments when ethephon, NAA and BA were used separately. No additional thinning occurred even in the combinations when ethephon was applied first at the balloon stage and NAA or BA applied later at 10 mm fruitlet diameter. Significant thinning response occurred only when tank mixed treatment of NAA + BA and sequential treatment of ethephon followed by tank mixture of NAA + BA were carried out. In this experiment, mean fruit weight and the share of bigger sized fruits (>70mm) increased significantly in all thinning treatments compared to the non thinned control trees.
Proučavali smo odaziv prorjeđivanja na šest godina starim stablima sorte 'Gala'/M.9. Izvedeni su postupci pojedinačnih aplikacija etefona 200 ppm u fenofazi crvene glavice, naftiloctene kiseline (NAA) 10 ppm ili benziladenina (BA) 100 ppm kada je promjer ploda iznosio 10 mm kao i uzastopni postupci etefonom nakon čega je slijedila NAA, odnosno BA ili u tanku pomiješani NAA + BA. Prorjeđivanje nije bilo signifikantno kod postupaka, u kojima su etefon, NAA i BA primijenjeni pojedinačno. Do dodatnog prorjeđivanja nije došlo ni u postupcima kada je etefon primijenjen najprije u balonskom stadiju, a NAA ili BA primijenjeni kasnije, kada je promjer plodova iznosio 10 mm. Signifikantan odaziv na prorjeđivanje dogodio se samo kada je izveden postupak s u tanku pomiješanim NAA + BA i uzastopni postupak etefonom nakon čega su slijedili u tanku pomiješani NAA + BA. U tom pokusu prosječna težina plodova i udio većih plodova (> 70 mm) signifikantno su se povećali kod svih postupaka prorjeđivanja u usporedbi s neprorjeđivanim stablima kontrole.

Istraživan je utjecaj folijarne primjene dušika, kalija i bora na razinu i dinamiku koncentracije dušika, kalija i bora u plodu masline sorte Oblica. Koncentracija dušika i kalija u plodu postupno se povećavala do razdoblja dozrijevanja, a razlike pod utjecajem folijarne primjene nisu bile statistički opravdane. Koncentracija kalija u lišću se postupno povećavala do razdoblja dozrijevanja plodova. Folijarna primjena bora odrazila se na signifikantno povećanje njegove koncentracije u plodu. Utvrđena je signifikantna korelacija između sadržaja kalija i ulja u plodu.
Influence of foliar nutrition with nitrogen, potassium and boron in comparison with untreated control trees on the level and seasonal changes of nitrogen, potassium and boron in the olive fruits cv. Oblica was observed over the growing season. The concentration of nitrogen and potassium in the fruit was gradually rising during the growing period until the time of fruit ripening, but the differences caused by foliar application of N, K and B were not significant. Foliar application of boron caused significantly higher fruit boron content. Significant positive correlation between oil and potassium content in the fruit was observed.

Tijekom 2005. i 2006. godine, prvi puta u Hrvatskoj je provedeno testiranje biljnog materijala masline na prisutnost virusa. Uzorci za testiranje su sakupljani na tradicionalnim maslinarskim područjima iz komercijalnih nasada masline, na dvadeset i pet lokaliteta. Uzorci su testirani na prisutnost osam vrsta virusa: ArMV, CMV, CLRV, OLV-1, OLV-2, OLRV, OLYaV i SLRV. Rezultati analiza provedenih primjenom RT-PCR metode, potvrdili su nazočnost virusa na oko 25 % uzoraka, a ukupno je potvrđena nazočnost četiri vrste virusa: OLYaV - Olive leaf yellowing-associated virus, CMV - Cucumber mosaic virus, OLV-2 - Olive latent virus 2 i SLRV – Strawberry latent ringspot virus.
Nazočnost virusa CMV je utvrđena na uzorcima sorata Istarska bjelica i Lastovka, SLRV na sortama Levantinka i Oblica, OLV-2 na sorti Lastovka, te OLYaV na sortama Bjelica, Istarska bjelica, Lastovka i Levantinka. Uzorci sorata Buža, Perišićeva mastrinka i Rosulja bili su negativni na nazočnost virusa.
During the years 2005 and 2006, testing of the olive plant material on the presence of olive viruses was conducted for the first time in Croatia. The samples for testing were collected from twenty five locations in commercial olive orchards, from traditional olive growing areas. All samples were teseted on the presence of eight virus types: ArMV, CMV, CLRV, OLV-1, OLV-2, OLRV, OLYaV and SLRV.
The results of analyses conducted by using the RT-PCR method, confirmed the presence of viruses in 25% of samples, and four virus types were confirmed: OLYaV - Olive leaf yellowing-associated virus, CMV - Cucumber mosaic virus, OLV-2 - Olive latent virus 2 and SLRV – Strawberry latent ringspot virus. Presence of CMV was confirmed on Istarska bjelica and Lastovka samples, SLRV was confirmed on Levantinka and Oblica samples, OLV-2 was confirmed on Lastovka samples, OLYaV was confirmed on Bjelica, Istarska bjelica, Lastovka and Levantinka samples. Samples of Buža, Perišićeva mastrinka and Rosulja cultivars were free from tested viruses.

The research has been conducted upon the cheery species called Stella, Creska, Van and Bing that were raised on the island of Cres. The quality of the fruits was analysed by the following parameters: dry matter, total acidity, total soluble solid, pH and L-ascorbic acid. The purpose of this research was to establish if there were any differences in above parameters between the explored species. The given results show that there were significant differences between the sorts. The species Stella had the largest quantity of vitamin C which amounted to 15.1 mg/100g while the sort Creska and Van had a bigger amount of the soluble solid (from 16.49 to 16.6%) and total soluble solid (from 16.0 to 16.4 °Brix). All obtained values were within satisfactory limits. We can conclude that from the aspect of cultivation and climate conditions of the island of Cres the mentioned species have good quality fruits.

Malus x domestica; internal and external fruit quality; hedonic scores
Istraživana je kakvoća plodova pet sorata jabuke, koje su zbog otpornosti na čađavu krastavost prikladne za sustav organske proizvodnje. Istraživanjima su obuhvaćene sorte Enterprise, Liberty, Nova Easygro, Sir Prize i Rewena. Kakvoća plodova utvrđena je standardnim metodama, pri čemu su kao vanjski parametric kakvoće utvrđeni: masa ploda, tvrdoća mesa ploda, sadržaj topive suhe tvari i ukupnih kiselina. Senzoričko vrednovanje, na osnovi panel testa, uključilo je: veličinu ploda, oblik i boju, tvrdoću, teksturu, sočnost, omjer šećera i kiselina, te aromu i ukupnu senzoričnu vrijednost. Nađene su značajne razlike između sorata glede senzoričnih ocjena. Ukupno gledano, istraživane sorte su, u odnosu na standardnu sortu Jonagold, postizale lošije ocjene.
Fruit quality of five scab resistant apple cultivars (Enterprise, Liberty, Nova Easygro, Sir Prize and Rewena) suitable for organic growing systems were tested. External and internal fruit quality was assessed through standard parameters (fruit weight, firmness, soluble solids, malic acid) and sensorial quality by panel tests (fruit size, shape and colour; hardness, texture, juiciness, sweet/acid taste, aroma and overall flavour). Large differences in sensory scores for particular quality attributes were found between cultivars. The hedonic scores showed significantly lower preference for tested scab resistant apple cultivars in comparison to ‘Jonagold’ as the reference cultivar

Da bi se istražila antioksidacijska aktivnost polifenola borovnice i jagode, ekstrahirane su dvije frakcije polifenola iz ovog voća. Jedna je sadržavala flavonole i fenolne kiseline, a druga antocijanine. Antioksidacijska aktivnost polifenola određena je DPPH testom, a količina polifenola HPLC metodom. Pokazalo se da se u borovnici nalaze visoke količine derivata kafeinske kiseline i kvercetina te antocijanina dok je u jagodi sadržaj polifenola manji. U obje vrste voća je doprinos antocijanina antioksidacijskoj aktivnosti veći nego doprinos flavonola i fenolnih kiselina. Antioksidacijska aktivnost antocijanina borovnice 19 puta je jača u usporedbi s antioksidacijskom aktivnošću flavonola i fenolnih kiselina borovnice. Antocijanini jagode 14 puta su jači antioksidansi nego flavonoli i fenolne kiseline jagode. Rezultati ovog rada pružaju bolji uvid u antioksidacijsko djelovanje borovnice i jagode.
In order to investigate antioxidant activity of polyphenols from blueberries and strawberries, two fractions of polyphenols were extracted from these fruits. Antioxidant activity of polyphenols was determined by DPPH test, and the polyphenols content by HPLC method. It was shown that blueberries contained high amount of caffeic acid derivatives, quercetin derivatives and anthocyanins, whereas the amount of polyphenols in strawberries was lower. In both berry species, the contribution of anthocyanins to antioxidant activity was higher than the contribution of flavonols and phenolic acids. Antioxidant activity of blueberry anthocyanins was 19 times higher than antioxidant activity of flavonols and phenolic acids in blueberries. Strawberry anthocyanins were 14 times stronger antioxidants than flavonols and phenolic acids from strawberry. The results of this study provide a better insight into antioxidant activity of blueberries and strawberries.

Sorte jabuka Gloster, Jonagold, Idared, Melrose i Mutsu s pro-izvodnog područja sjeverozapadne Hrvatske ubrane su u tehnološkoj zriobi i skladištene u rashladnom prostoru na prosječnoj temperaturi od 2,0 oC i relativnoj vlazi zraka od 98% do užitne dospjelosti.
Plodovi jabuka namijenjeni za sušenje očišćeni su i rezani na kockice veličine 1x1x1 cm. Količina mesa u analiziranim sortama je 63,37-75,46 %, količina kožica je 9,11-12,85 %, količina sjemene lože je 10,82-20,34 % i količina neupotrebljivog dijela je 0,25-0,87 %.
Pripremljene kockice potapane su u šećerni sirup gustoće 64oBx kroz 24 sata. Sušenje kockica rađeno je u pet ponavljanja na labora-torijskoj sušari RETSCH TG 1, uz temperaturu zraka od 50 oC do 60 oC. Brzina zraka za sušenje iznosila je 2,0–3,5 m/s, a vrijeme sušenja trajalo je 140 minuta. Prosječna količina uzorka za sušenje je 250 grama. Količina vode u svježim kockicama je 85,11-86,89 % u kockicama nakon potapanja u šećerni sirup 63,96-72,03 % i u suhim kockicama 15,65-17,92 %. Prosječne krivulje brzine sušenja modelirane su polinomnom regresijom i dobivene su sljedeće jednadžbe:
Sorta Gloster y = 0,0028x2 – 0,7420x + 67,025 uz r = - 0,9988; R2 = 0,9978
gdje je: y – količina vode (%);x – vrijeme sušenja (min)
Sorta Jonagold y = 0,0044x2 – 0,9620x + 67,96 uz r = - 0,9864; R2 = 0,9731
Sorta Idared y = 0,0042x2 – 0,8850x + 60,501 uz r = - 0,9840; R2 = 0,9684
Sorta Melrose y = 0,0030x2 – 0,7864x + 69,707 uz r = - 0,9983; R2 = 0,9967
Sorta Mutsu y = 0,0031x2 – 0,7348x + 61,090 uz r = - 0,9855; R2 = 0,9714
Sorte Jonagold i Idared u postupku sušenja brže otpuštaju vodu. Indeks rehidracije suhih kockica istraživanih sorti je 2,29-2,68.
Senzoričko ocjenjivanje kakvoće osušenog proizvoda pokazalo je zadovoljavajuće ocjene za okus, miris i konzistenciju kockica kod svih sorata. Kockice sorte Gloster u senzoričkom ocjenjivanju boje nisu postigle zadovoljavajuće vrijednosti.
Apple varieties Gloster, Jonagold, Idared, Melrose and Mutsu from the production region of North-western Croatia were picked at technological maturity and cool stored at an average temperature of 2.0 oC and relative humidity of 98 % until consumable maturity.
Apple fruits intended for drying were cleaned and cut into 1x1x1 cm cubes. Analyzed varieties had 63.37-75.46 % of flesh, 9.11-12.85 % of skin, the core accounted for 10.82-20.34 % and the unusable part for 0.25-0.87 %. Prepared cubes were soaked in sugar syrup of 64oBx density for 24 hours. Cube drying was carried out in five replications in a RETSCH TG 1 laboratory dryer, at air temperature from 50 oC to 60 oC. Drying air velocity was 2.0–3.5 m/s, drying time was 140 minutes. Average drying sample size was 250 grams.
Fresh cubes contained 85.11-86.89 % of water, cubes soaked in sugar syrup 63.96-72.03 %, and dry cubes 15.65-17.92 %.
Average drying rate curves modelled by linear regression gave the following equations:
Gloster y = 0.0028x2 – 0.7420x + 67.025, with r = - 0.9988; R2 = 0.9978 where: y – water content (%); x – drying time (min)
Jonagold y = 0.0044x2 – 0.9620x + 67.96 uz r = - 0.9864; R2 = 0.9731
Idared y = 0.0042x2 – 0.8850x + 60.501 uz r = - 0.9840; R2 = 0.9684
Melrose y = 0.0030x2 – 0.7864x + 69.707 uz r = - 0.9983; R2 = 0.9967
Mutsu y = 0.0031x2 – 0.7348x + 61.090 uz r = - 0.9855; R2 = 0.9714
Jonagold and Idared varieties released water faster during the drying procedure.
The rehydration index of dry cubes of the studied varieties was 2.29-2.68. Sensory evaluation ratings of the dry product quality were satisfactory for the taste, smell and consistency of cubes of all varieties. Sensory evaluation rating for the colour of Gloster apple cubes was not satisfactory.

Boris Duralija
partenokarpija; kruška; sorte
parthenocarpy; pear; cultivars
Partenokarpija je zametanje i razvoj ploda bez oplodnje. Partenokarpijom se u nekih sorti mogu, u većem ili manjem opsegu, povećati prirodi, osobito u onim okolinskim uvjetima i godinama koje nisu povoljne za oprašivanje, odnosno oplodnju, što je značajno za voćarsku proizvodnju osobito s ekonomskog gledišta.
Članak obuhvaća formiranje partenokarpnih plodova, vrste, intenzitet i stimuliranje partenokarpije, osobine partenokarpnih plodova kruške, sklonost pojedinih sorata kruške partenokarpiji i na kraju važnost partenokarpije.
Parthenocarpy is fruit set and development without fertilization. With parthenocarpy at some varieties in major or smaller extent may increase yield, especially in environmental conditions and years which are not favourable for pollination and fertilization, what is significant for fruit production especially from economic position.
The article gives a survey of formation of parthenocarpic fruits as well as kind, intensity and stimulation of parthenocarpy, characteristic of parthenocarpy fruit of pear, affinity of individual varieties of pear to parthenocarpy and in the end meaning of parthenocarpy.

Problemi oprašivanja kruške
Difficulties in pear pollination
Marija Ševar
kruška; pčela medarica; bumbari; solitarne pčele iz roda Osmia
pear; honeybee; bumblebees; solitary bees
Pogodna svojstva tla i optimalni ekološki uvjeti nisu dostatni za uspješnu proizvodnju kruške. Ograničavajući čimbenici su: klimatski, odabir sortimenta, odabir podloge, te vrste i brojnost kukaca oprašivača. Pri podizanju nasada kruške zanemaruje se problem oprašivanja kukcima, jer vlada uvjerenje da će krušku oprašiti pčele medarice (Apis mellifera). Voćari moraju razmišljati i o uporabi drugih kukaca: bumbara (Bombus spp.) i solitarnih pčela iz roda Osmia (Osmia rufa i Osmia cornuta), jer od uspjeha oprašivanja ovisi ne samo krupnoća ploda već i prirod. U novije vrijeme svjedoci smo i primjene hormonskih pripravaka za oprašivanje voćaka.
Proper characteristics of soil and optimal ecological conditions are not enough for successful pear production. Restrictive factors are climate, sort selection, foundation selection, sort and number of pollinators. When establishing a pear plantation, people neglect the problem of insects' pollination for believe that honeybees will pollinate pears (Apis mellifeara). Fruit producers have to think of other insects usage: bumblebees (Bombus spp.) and solitary bees from Osmia genus (Osmia rufa and Osmia cornuta). Yield and size of the fruit depend on the success of pollination. Lately we witnesses of hormone preparation treatment for pollination.

Proizvodnja rogača u Hrvatskoj ima veoma dugu tradiciju ali nikada kroz povijest uzgoja nije imala mjesto koje ova kultura zaslužuje s obzirom na kakvoću i iskoristivost ploda. Posebno je zabrinjavajuća činjenica veoma slabog poznavanja domaćeg sortimenta rogača. S ciljem vrednovanja i unaprjeđenja ove kulture započeli smo projekt odabira rogača iz populacija s otoka Visa. Prema priloženoj metodologiji istraživanja odabrali smo dva fenotipa koje smo opisali s fenološkog, morfološkog, pomološkog i agronomskog aspekta. Rezultati istraživanja ukazuju na postojanje veoma velike varijabilnosti svojstava u izvornim populacijama.
Production of carub in Croatia has very long tradition, however throughout history of breeding, it did not have a place that it deserves, considering the quality and use of its fruits. The lack of knowledge of domestic assortment is especially troubling. With the goal of evaluating and furthering this culture, we started the project of carob selection from natural population of the Island of Vis. According to enclosed research methodology we selected two phenotypes, which we described from phenological, morphological, pomological and agricultural aspect. Research results show that there is a great variability in characteristics of natural populations.

U ovom istraživanju ispitivan je utjecaj tri različita sustava uzgoja, na otvorenom polju u plastičnom tunelu i u hidroponu, na kakvoću plodova sorte Elsanta. Na osnovi dobivenih rezultata možemo ustvrditi kako su svi sustavi uzgoja dali plodove zadovoljavajuće kakvoće, no ipak najbolju kakvoću na osnovi fizikalno-kemijskih parametara postigli su plodovi uzgajani u plasteniku. Najslabije rezultate postigli su plodovi uzgajani u hidroponskom sustavu uzgoja.
In this research influence of three different cultivation systems, open field, plastic tunnel and hydroponics on fruit quality of cultivar Elsanta was investigated. From the obtained data we can conclude that all cultivation systems produced fruits of satisfying quality. However, based on physical and chemical parameters fruits grown in plastic tunnels achieved the best quality. Fruits grown in hydroponics attained somewhat lower results.

Istraživani su kemijski sastav i senzorna svojstva rakija proizvedenih od šljive (Prunus domestica) kultivara Elena, Top i Felsina. Sukladno rokovima dozrijevanja tri su sorte šljive odvojeno, fermentacijom masulja bez koštica i primjenom klasičnih postupaka destilacije, u pokusu postavljenom u tri ponavljanja, prerađene u rakiju. Koncentracije metanola u rakijama ispitivanih sorti šljive bile su ispod vrijednosti, propisima maksimalno dopuštene za rakiju šljivovicu. Najvišu koncentraciju metanola imali su destilati šljive kultivara Elena. Najviše koncentracije viših alkohola, etil-acetata i acet-aldehida imali su destilati šljive sorte Felsina. U odnosu na destilate ostalih sorti destilati kultivara Felsina razlikovali su se u omjeru koncentracija pojedinih viših alkohola. Provedenom senzornom analizom najvišu je ocjenu za kakvoću dobila rakija proizvedena od šljive sorte Elena.
Chemical composition and sensory characteristics of brandies derived from plum (Prunus domestica) cultivars Elena, Top and Felsina were investigated. Three plum cultivars harvested according to the maturity period were separately crushed, fermented without stones in an assay in three replications, and distilled by classical procedure to make the brandy. The methanol content in brandy of each investigated cultivar was below maximal amounts proscribed by the law for plum brandy. The highest concentration of methanol in plum distillates of cv. Elena was determined. Distillates made from cultivar Felsina contained the highest concentrations of higher alcohols, ethyl acetate and acetaldehyde. Compared to distillates from other cultivars Felsina distillates differed in higher alcohols concentrations ratio. According to sensory analyses brandy produced from cultivar Elena was the best.

Optimal conditions for in vitro multiplication and rooting of cv. Willamette were investigated. High level of proliferation and multiplication after 90 days of culture on Murashige and Skoog (MS) medium with 100 mg·l-1 myo-inositol, 2 mg·l-1 thiamine-HCl, 1 mg·l-1 piridoxine-HCl, 1 mg·l-1 nicotinic acid and 30 g·l-1 sucrose and 8 g·l-1 agar was considered together with two concentrations of BA (0,2 and 2 mg·l-1). Half strength MS medium was also used. There was a significant variation of the proliferated shoots, depending on media. We got high level of rooting and we have investigated acclimatization of regenerants grown on sterile substrate in conditions of high humidity.
Istraživani su optimalni uvjeti za razmanžanje i ukorjenjivanje kultivara Willamette in vitro. Visok stupanj proliferacije i razmanžanja nakon 90 dana kulture na Murashige i Skoog (MS) mediju sa 100 mg·l-1 mio inositola, 2 mg·l-1 tijamina-HCl, 1 mg·l-1 piridoksina-HCl, 1 mg·l-1 nikotinske kiseline, 30 g·l-1 saharoze i 8 g·l-1 agara razmatran je s dvije koncentracije BA (0,2 i 2,0 mg·l-1). Primijenjen je i medij MS pola koncentracije. Značajno je bilo odstupanje proliferiranih izboja, ovisno o mediju. Dobili smo visoku razinu ukorjenjenja te smo istražili prilagodbu ponovno naraslih izboja na sterilnom supstratu u uvjetima obilne vlage.

U dvogodišnjem istraživanju uvjeta za primarne infekcije fuzikladijem Venturia inaequalis i broja zaštita od ove ekonomski važne bolesti jabuke u tri različita ekologijska uvjeta Hrvatske, ustanovljene su velike razlike u broju primarnih infekcija i broja potrebnih zaštita. Izbor staništa u podizanju voćnjaka utjeće na ekonomsku i ekološku opravdanost integrirane proizvodnje jabuke. Integrirana zaštita u integriranoj proizvodnji u ulozi je ekološke povoljnosti zbog ekološki povoljnijih sredstava za zaštitu bilja koji su dozvoljeni u ovom sustavu proizvodnje.
In the two years monitoring of primary scab infection Venturia inaequalis and the number of treatments against this major apple disease in three ecological conditions of Croatia serious differences were found in the number of primary infections and the number of treatments. The location of new orchards has important influence on economic and ecological validity of integrated apple production. Integrated plant protection in integrated production is ecologically advantageous, because of ecologically safer agrochemicals permitted in this production system.

The main grown citrus crop in Croatia is Satsuma mandarin (Citrus unshiu Marc.). The preliminary surveys have shown widespread occurrence of the most devastating citrus pathogen, Citrus tristeza virus (CTV) in Croatia. In this research four Satsuma mandarin cultivars: Chahara, Ichimaru, Kuno and Zorica Rana were biologically tested for the presence of CTV on Mexican lime (Citrus aurantifolia Swingle) bioindicator. Displayed symptoms strongly suggest the existence of mild CTV strains in four tested mandarin cultivars. Laboratory diagnostic methods (DTBIA, DAS-ELISA, IC/RT-PCR) confirmed these findings. Plants of cv. Kuno mandarin underwent sanitation treatments which consisted of thermotherapy and shoot-tip grafting (STG; micrografting) on in vitro germinated Troyer citrange [Poncirus trifoliata (L.) Raf. x Citrus sinensis (L.) Osbeck)] rootstock. Tristeza-virus was eliminated from 42% of infected ’Kuno’ mandarins (confirmed by DTBIA). Completion of the above mentioned procedures will help development and implementation of citrus certification program in Croatia which would ensure the production of high-quality citrus propagating material in both sanitary and pomological aspects.
Najčešće uzgajana i komercijalno najznačajnija vrsta agruma u Hrvatskoj je mandarina Unshiu (Citrus unshiu Marc.), ponajviše zbog njene otpornosti na niske temperature karakteristične za ovo geografsko područje. U većini područja gdje se uzgajaju agrumi, kako u svijetu, tako i u nas, česta je pojava bolesti 'tristeza', najopasnije i najrasprostranjenije virusne bolest agruma, a čiji je uzročnik Citrus tristeza virus (CTV). U ovo istraživanje bila su uključena četiri kultivara mandarine Unshiu: Chahara, Ichimaru, Kuno i Zorica Rana, koji su podvrgnuti biološkom indeksiranju na meksičkoj limeti (Mexican lime; Citrus aurantifolia Swingle), najpogodnijoj indikatorskoj vrsti za detekciju virusa tristeza. Rezultati biološkog indeksiranja ukazali su na postojanje blagih sojeva tristeza-virusa u testiranim kultivarima, što je potvrđeno i egzaktnim molekularno-biološkim metodama (DTBIA, DAS-ELISA, IC/RT-PCR). Zaraženi klonovi kultivara Kuno podvrgnuti su postupku eliminacije virusa primjenom toplinskog tretmana te cijepljenjem malenog vegetacijskog vrška plemke na bezvirusni sjemenjak podloge Troyer citrange [Poncirus trifoliata (L.) Raf. x Citrus sinensis (L.) Osbeck], prethodno uzgojen u uvjetima in vitro mikrocijepljenje). Nakon kultiviranja mikrocijepljenih biljaka i adaptacije na stakleničke uvjete, virus tristeza eliminiran je iz 42% zaraženih biljaka cv. Kuno, što je potvrđeno testom DTBIA.
Rezultati ovog istraživanja trebali bi potaknuti izradu certifikacijskog programa za agrume, ali i za druge voćne vrste, koji bi omogućili proizvodnju visoko kvalitetnog sadnog materijala, kako u zdravstvenom, tako i u pomološkom pogledu.

In conditions of Ulcinjsko polje, during the period 1987-1991, growth intensity of one-year old olive shoots and fruit growth in Picholine variety were investigated. Related to that, the dynamics of mineral nutrition (N, P, K, Ca and Mg) was followed in leaves and fruits in the period from middle of July to the middle of October. Results showed that nutrient status during vegetation period was within optimal values for olive. Decreasing dynamics during vegetative period was in N (from 2.22% to 1.67%). Slight increasing dynamic was showed in K (1.15% to 1.32%), Ca (0.91% to 1.22%) and Mg (0.17% to 0.21%), while P had a relatively stable content in olive leaves (0.19%). Nutrient status in the fruit showed different tendencies. Decreasing dynamics showed N (0.81 to 0.59%), Ca (260 to 229 ppm) and Mg (228 to 191 ppm). Slight increment showed P (0.13 do 015%) and K (1.44 do 1.51 %).

Systematic overview of plant structure on different localities had shown rich populations of wild fig trees and existence of morphological differences between trees. On the basis of comparing and taking into account basic characteristics such as growth habit, characteristics of leaves and blooms, certain trees as potential types of wild fig that can be found in Herzegovina have been differentiated.
During the years of research (2001, 2002, 2003), phenological observation of blooming on separated trees of wild fig was ben done. Time of blooming was monitored, i.e. maturation of selected types of wild fig. Description of wild fig types included description of growth, leaves and inflorescence (number of inflorescences, number of gall flowers, presence of female flowers, number of male flowers, time for pollen maturation, and time, rate and duration of Blastophaga’s exit and presence of parasitic insects) with the use of standardized description lists for fig.
Sustavnim pregledom biljnih sastojina na različitim lokalitetima uočene su bogate populacije stabala divlje smokve i postojanje morfoloških različitosti između stabala. Temeljem međusobnih usporedbi i vodeći računa o osnovnim svojstvima kao što je habitus, svojstva listova i cvatova izdvojena su određena stabla kao potencijalni tipovi divlje smokve koji se mogu pronaći i rastu na području Hercegovine. Tijekom godina istraživanja (2001., 2002. i 2003.) obavljeno je fenološko zapažanje cvatnje izdvojenih stabala divlje smokve. Praćeno je vrijeme cvatnje, odnosno dozrijevanje odabranih tipova divlje smokve. Opis tipova divlje smokve obuhvatila je opis rasta, lista i cvata (broj cvati, broj šiškastih cvjetova, prisutnost ženskih cvjetova, broj muških cvjetova, vrijeme zriobe polena zatim vrijeme, stupanj i trajanje izlaska osice Blastophaga te prisutnost parazitskih insekata) pri čemu su se koristile standardizirane deskripcijske liste za smokvu.

The study was conducted on the cultivars Regina, Karina, Creska and Stella cultivated in continental and Mediterranean regions of Croatia. The cultivars Regina and Karina were cultivated at the scientific and experimental station Jazbina, while Creska and Stella were cultivated on the island of Cres. Sugar quantity (glucose, fructose and sucrose) was determined by using enzyme technique. The purpose of this study was to examine whether there were differences in the quantity of certain sugars, between studied species and at defferent sites, depending on the climate. The obtained results demonstrate that there are significant differences between the studied species. E.g. cultivar Stella had the highest amount of fructose (7.73%), while the highest amount of glucose was found in Regina (7.62%) and Creska (7.00%). The quantity of sucrose was low in all investigated cultivars. The lowest amount was determined in the cultivar Regina 0.003 %, and the highest in the cultivar Creska 0.183 %. In the cultivar Karina, sucrose was not determined in the sample.
Based on obtained results we can conclude that in climatic conditions of the Mediterranean and continental Croatia, investigated cultivars have a satisfactory quantity of sugars.
Provedeno je istraživanje na sortama Regina, Karina, Creska i Stella uzgojenim na području mediteranske i kontinentalne Hrvatske. Sorte Regina i Karina uzgojene su na lokalitetu znanstveno - nastavnog poligona Jazbina, a Creska i Stella na lokalitetu otoka Cresa. Enzimatskom metodom određena je količina šećera (glukoza, fruktoza i saharoza). Cilj ovog istraživanja bio je ustanoviti postoje li razlike u količini pojedinih šećera između istraživanih sorti i na različitim lokalitetima ovisno o klimatskim faktorima. Dobiveni rezultati pokazuju da postoje signifikantne razlike između istraživanog sortimenta. Istraživane sorte su se malo razlikovale u količini šećera s obzirom na klimu. U svim istraženim sortama bila je najveća količina glukoze, koja se kretala od 6,28 % (Stella) do 7,62 % (Regina), osim kod sorte Stella, gdje je fruktoza bila veća od glukoze i iznosila je 7,73 %. Količina saharoze u svim sortama bila je mala. Iznosila je najmanje kod sorte Regina 0,003 %, odnosno najviše kod sorte Creska 0,183 %. Kod sorte Karina saharoza nije detektirana u uzorku. S obzirom na dobivene rezultate može se zaključiti da u uzgojnim i klimatskim uvjetima mediteranske i kontinentalne Hrvatske navedene sorte imaju zadovoljavajuću količinu šećera.

Chokeberry and elderberry fruits are rich sources of polyphenols, the compounds with significant antiradical and chelating properties. They are studied intensively because of beneficial effects on human health. In this study, three fractions enriched with different classes of polyphenols were isolated from chokeberry and elderberry to study their antiradical activity by DPPH test. The first fraction contained flavonols and phenolic acids, the second anthocyanins, and third proanthocyanidins. The polyphenol content was determined by reversed-phase high performance liquid chromatography. Anthocyanins were found to be the main polyphenolic components of these berries with the highest portion in total antiradical activity, followed by proanthocyanidins and phenolic acids and flavonols. Furthermore, proanthocyanidins were found to be more effective in free DPPH• radical scavenging than flavonols, phenolic acids and anthocyanins. A biphasic reaction was observed in reaction between DPPH• radicals and polyphenols, at “fast” and “slow” scavenging rate. All classes of polyphenols showed strong antiradical activity in the first fast period, while in the slow period antiradical activity of polyphenols decreased. This kind of biphasic reaction could be important in biological activity of chokeberry and elderberry. This study is a contribution to a better understanding of antiradical activity of polyphenols from chokeberry and elderberry.
Plodovi aronije i bazge bogat su izvor polifenola, spojeva sa značajnim antiradikalnim osobinama i osobinama stvaranja helata. Istražuju se intenzivno zbog pozitivnog utjecaja na ljudsko zdravlje. U ovom istraživanju izolirane su tri frakcije iz aronije i bazge obogaćene različitim skupinama polifenola da bi se istražila njihova antiradikalna aktivnost pomoću DPPH testa. Prva frakcija sadržavala je flavonole i fenolne kiseline, druga antocijanine, a treća proantocijanidine. Količina polifenola određena je reverzno-faznom tekućinskom kromatografijom visoke djelotvornosti. Pronađeno je da su antocijanini glavne polifenolne komponente ovog voća s najvećim udjelom u ukupnoj antiradikalnoj aktivnosti, a slijede ih proantocijanidini te fenolne kiseline i flavonoli. Pokazalo se također da su proantocijanidini efektivniji u hvatanju slobodnih DPPH• radikala od flavonola, fenolnih kiselina i antocijanidina. Opažena je bifazna reakcija u reakciji između DPPH• radikala i polifenola sa „brzim” i „sporim” razdobljem hvatanja. Sve skupine polifenola pokazale su snažnu antiradikalnu aktivnost za vrijeme prvog brzog perioda, dok je antiradikalna aktivnost opadala za vrijeme sporog razdoblja. Ovakva bifazna reakcija mogla bi biti važna u biološkom djelovanju aronije i bazge. Ovo istraživanje predstavlja doprinos boljem razumijevanju antiradikalne aktivnosti polifenola iz plodova aronije i bazge.

Krunoslav Dugalić
Malus x domestica; internal and external fruit quality; hedonic scores
Malus x domestica; vanjska i unutrašnja kakvoća ploda; senzoričke ocjene
Fruit quality of five scab resistant apple cultivars (Enterprise, Liberty, Nova Easygro, Sir Prize and Rewena) suitable for organic growing systems were tested. External and internal fruit quality was assessed through standard parameters (fruit weight, firmness, soluble solids, malic acid) and sensorial quality by panel tests (fruit size, shape and colour; hardness, texture, juiciness, sweet/acid taste, aroma and overall flavour). Large differences in sensory scores for particular quality attributes were found between cultivars. The hedonic scores showed significantly lower preference for tested scab resistant apple cultivars in comparison to ‘Jonagold’ as the reference cultivar.
Istraživana je kakvoća plodova pet sorata jabuke, koje su zbog otpornosti na čađavu krastavost prikladne za sustav organske proizvodnje. Istraživanjima su obuhvaćene sorte Enterprise, Liberty, Nova Easygro, Sir Prize i Rewena. Kakvoća plodova utvrđena je standardnim metodama, pri čemu su kao vanjski parametric kakvoće utvrđeni: masa ploda, tvrdoća mesa ploda, sadržaj topive suhe tvari i ukupnih kiselina. Senzoričko vrednovanje, na osnovi panel testa, uključilo je: veličinu ploda, oblik i boju, tvrdoću, teksturu, sočnost, omjer šećera i kiselina, te aromu i ukupnu senzoričnu vrijednost. Nađene su značajne razlike između sorata glede senzoričnih ocjena. Ukupno gledano, istraživane sorte su, u odnosu na standardnu sortu Jonagold, postizale lošije ocjene.

mandarina unshiu; toplinski predtretman; gubitak na težini, kakvoća ploda
'Owari' Satsuma mandarin; hot water dipping pre-treatment; fruit weight loss; mandarin fruit quality
Istraživan je utjecaj toplinskih predtretmana potapanjem plodova u toplu vodu na 48°C (HWD 48) i 52°C (HWD 52) te kontrole (izostanak predtretmana) na kakvoću plodova mandarine (Citrus unshiu Marc., cv. Owari) nakon 8 tjedana skladištenja na temperaturi od 1 oC. Dobiveni rezultati upućuju da je kod plodova tretiranih toplom vodom došlo do manjeg gubitka na težini u odnosu na kontrolu, a utvrđen je signifikantan utjecaj predtretmana na kakvoću plodova. Boljim predtretmanom se pokazao HWD 48 čijom su se primjenom postigli najmaji gubitci plodova na težini, a zadržala zadovoljavajuća kakvoća.
Influence of hot water dipping pre-treatments at 48°C (HWD 48) and 52°C (HWD 52) on Satsuma mandarin fruits (Citrus unshiu Marc., cv. Owari) quality was studied. Measurements of fruit weight loss and basic chemical parameters of fruit quality were carried out after 8 weeks of storage at 1°C temperature. Obtained results indicate that fruits treated by hot water dips underwent a smaller weight loss than those not treated – the control fruits. Besides, a significant impact of applied pre-treatments on fruit quality was found. It was demonstrated that better pre-treatment was HWD 48 by whose utilization mandarin fruits underwent the smallest weight loss and at the same time maintained satisfactory quality.

U radu su iznesene pomološke i kemijske osobine lokalnih sorata trešnje koje se tradicionalno uzgajaju na području Dalmacije u usporedbi sa introduciranim sortama Bigarreau Burlat, Garnet, Isabella, Stella i Ferrovia. Istraživanje je provedeno prema deskriptorima za trešnju. Na temelju rezultata istraživanja za područje Kaštela izdvajamo: Gomiličku, Stonsku, Ranu Stonsku i Tugarku, a na području Poljica Tugarku kao vrlo kvalitetne i zanimljive sorte za intenzivniju proizvodnju svježeg ploda. Osim navedenih i ostale tradicionalno uzgajane sorte potrebno je prikupiti u svrhu očuvanja vrijednog genetskog materijala.
Pomological and chemical characteristics of local sweet cherry cultivars traditionally grown in Dalmatia are presented in this paper and compared to introduced cultivars: “Bigarreau Burlat”, “Garnet”, “Isabella”, “Stella” and “Ferrovia”. The research was done using descriptors for cherry. Based on our study in Kastel area we selected: “Gomilička”, “Stonska”, “Rana Stonska” and “Tugarka” and in Poljica area the cultivar “Tugarka” as high quality and interesting cultivars for intensive production of fresh fruit. Besides the mentioned, others cultivars need to be collected for conservation of valuable genetic material.

Cilj istraživanja bio je ispitati mogućnost upotrebe metoda procesiranja i analiziranja slike za ranu prognozu uroda jabuka sorti Golden Delicious, Jonagold i Idared, cijepljenih na podlozi M9 u pedoklimatskim uvjetima Međimurja. Kod analize slike najbolje prognoze u prosjeku su dobivene u srednje kasne sorte Idared (-734
kg/ha), a najslabije kod sorte Golden Delicious (-4.700 kg/ha), dok je kod sorte Jonagold urod u prosjeku precijenjen za 3.266 kg/ha. U buduća istraživanja potrebno je uključiti i ostale sorte iz asortimana te prilagoditi krivulje rasta lokalnim pedoklimatskim uvjetima.
The possibility of digital imaging and image processing for early forecasting of the apple yield was researched in the varieties Golden Delicious, Jonagold and Idared grafted on M9 in nine orchards of the Međimurje county (Croatia). Each variety was tested on three locations, whereby the highest accuracy was achieved with Idared (-734 kg/ha), followed by Jonagold (+3.266 kg/ha) and Golden Delicious (-4.700 kg/ha). The future experiments will involve new locally adopted growing curves and other apple varieties growing on locally.

Produzioni e Biodiversità nella moderna Olivicoltura
Proizvodnja i bioraznolikost u modernom maslinarstvu
Production and biodiversity in modern olive growing

Đ. Žužić
U EU je shvaćena bit konvencije iz Ria de Janeira da se na bioraznolikosti moraju temeljiti poljoprivredne politike. Ruralna politika EU predviđa uostalom čitav niz agroambijentalnih mjera koje nagrađuju poljoprivredna poduzeća koja prakticiraju akcije održivog ambijentalnog razvoja. Situacije koje su smatrane kao prijetnje okolišu jesu, pretjerano iskorištavanje resursa, nestanak bioraznolikosti i napuštanje tala što može prouzročiti gubitak obrađenog sloja, stolječima obrađivanog od strane čovjeka koji je dao ruralnom ambijentu dignitet habitata i pejzaža. Maslinarstvo, svojstveni element mediteranskog pejzaža predstavlja u tom smislu primjer kulture zaštite i sveopćeg održavanja. Usmjerena politika održivosti mora odgovarati ekonomskom, socijalnom i ekološkom problemu, osim favoriziranja usmjerene proizvodnje u interesu potrošača. Maslinarstvo ne implicira nužnost povratku tradicionalnom načinu obrađivanja kao kod slučaja biološke proizvodnje kada se mora voditi računa o fitosanitarnom i prirodnom načinu proizvodnje kako bi izbjegli korištenje pesticida.Ponovni pokušaji razvoja maslinarstva ne mogu se oslanjati na dotada korišteni biljni materijal. Treba analizirati fleksibilnost genotipa ne bi li slučajno provocirali eventualnu biološku katastrofu, što se već desilo kod ostalih voćnih vrsta nekontroliranom upotrebom sorata od jednog do drugog područja potpuno različitih osobina. Time je sortama oduzeta odlučujuća uloga svojstvene proizvodnje. Događaji koji naslućuju privredno oživljavanje modernog maslinarstva i u onim zemljama gdje nema tradicionalne proizvodnje, razni međunarodni pokušaji usmjereni prema zaštiti bioraznolikosti sačinjavaju idealni instrument za promociju novih modela za održivu proizvodnju.
The UN have grasped the idea of the Convention in Rio de Janeiro to make biodiversity the keystone of agricultural policy.Plans in the rural policy in the UN include a series of agroenvironmental measures to reward agricultural firms practising sustainable environmental development.
The situations considered damaging for the environment are overexplotation of resources,disappearance of biodiversity and abandonment of soils which may cause loss of the layer that has been cultivated by man for centuries giving the rural environment dignity of habitat and landscape.
Olive growing,a characteristic element of Mediterranean landscape is an example of protection and general survival.The targeted policy of sustainability must meet the economic,social and ecological problems besides favouring targeted production in the interest of consumers.
Olive growing respecting the environment does not mean returning to traditional cultivation as in the case of biological production when phytosanitary and natural methods of production must be considered in order to avoid the use of pesticides.
Repeated attempts to develop olive growing cannot rely on the plant material used so far.Genotype flexibility should be analyzed not to provoke a biological disaster which has already happened with other fruit varieties by unconrolled use of varieties in areas of quite different characteristics.Thus the varieties have been deprived of their important role in production. The events indicative of economic revival of modern olive growing in the countries where olives have not been traditionally grown,various international attempts directed at protection of biodiversity are an ideal instrument of sustainable production.

Le Acque Reflue dei Frantoi Oleari: Smaltimento o Valorizzazione?
Vegetativne vode od prerade maslina: zbrinjavanje ili valorizacija
Vegetation waters from olive oil refineries: taking care of /disposing and evaluation/
F. Federici
M. Petruccioli
Odgovor na postavljeno pitanje da li se vegetativne vode od prerade maslina moraju zbrinjavati ili valorizirati vjerojatno je očekivan. U današnje vrijeme se velike količine vegetativnih voda izravno izlijevaju na poljoprivredne površine ne vodeći računa o
mogućem zagađivanju tla. Rezultati provedeni od strane naše znanstvene ekipe kao i u drugim državama, pokazuju jasno da vegetativna voda može biti podvrgnuta agroindustrijskoj obradi u valoriziranju kroz razne biotehnološke, odnosno kemijske
procese. Ne smiju se zaboraviti, odnosno podcjenjivati razne zapreke i poteškoće koje bi se pojavile u eventualnom procesu, primjera radi visoke varijabilnosti kemijskog sastava vegetativnih voda kao i potreba brižljivog uskladištenja. Zato, valorizacija kroz
kemijske odnosno biotehnološke procese može biti predviđena i aplicirana sa uspjehom za ograničene količine vegetativnih voda i tamo gdje dodana vrijednost opravdava investiciju.
The answer to the initial question whether vegetation waters from oil processing should be taken care of disposed of or evaluated is probably expected. Owing to large amounts of vegetation waters which can highly pollute the environment and a possibility that they can be spread over agricultural land the latter is
today widely used without an alternative. The results obtained by our team as well as experts in other countries show that vegetation waters residues can be agriculturally processed and evaluated in various biotechnological or chemical processes Various obstacles and difficulties that may occur in processing due to high variability of chemical composition of vegetation waters as well as the need for careful storing must not be forgotten or underestimated. Therefore, valorization through chemical or biotechnological processes can be planned and successfully applied in limited amounts of vegetation waters where additional expenses justify the investment

Istraživani su rast i rodnost stabala šljive uzgajane na teškom tlu u razdoblju od tri godine nakon sadnje (2005-2007). Eksperimentom su bile obuhvaćene sorte šljive Topfirst, Topfive, Topstar plus, Topgigant plus, Top 2000, Tophit plus, JoJo i Haganta cijepljene na podlozi WaxWa, sađene na razmaku 4,0 x 2,5 m (1000 stabala/ha).
Vegetativni rast, izražen površinom poprečnog presjeka debla u velikoj mjeri je ovisio o sorti i bio je manji u sorata Topgigant, Top 2000 i Haganta, veći u sorti Topfirst i Topfive, te još veći u sorte Topstar, a najveći u sorte Tophit. Prema vremenu dozrijevanja i kakvoći plodova posebnu su vrijednost očitovale sorte Topfirst, Topfive i Jojo. Podloga WaxWa se pokazala prikladnom za intenzivan uzgoj šljive u gustom sklopu.
An investigation into the growth and cropping of plum trees, which were cultivated on heavy soil, was conducted for three years after planting (2005-2007). The experiment included plum cultivars Topfirst, Topfive, Topstar plus, Topgigant plus, Top 2000,
Tophit plus, JoJo and Haganta, grafted on rootstock WaxWa, and planted at the distance 4.0 x 2.5 m (1000 trees/ha). Tree vigour expressed as trunk cross-sectional area of Topgigant, Top 2000 and Haganta was lower than of Topfirst and Topfive, whereas tree
vigour of Topstar was higher and of Tophit was the highest. In our growing conditions, among cultivars in the trial, Topfirst, Topfive and Jojo showed good properties in view of ripening time, yield and fruit quality. Rootstock WaxWA looks as promising for modern, intensive plum growing at high density.

Malus domestica; Fuji; prirod; stanište; položaj ploda u krošnji; kakvoća ploda
Malus x domestica; sv.Fuji; yield; orchard site; fruit distribution within canopy; fruit quality
Istraživan je utjecaj uvjeta staništa i položaja plodova u krošnji na prirod, vanjske (veličina ploda, obojenost kožice ploda) i unutrašnje parametre kakvoće (sadržaj topive suhe tvari, sadržaj kiselina, tvrdoća mesa, škrobni indeks). U pokusu je bila sorta Fuji,
cijepljena na podlozi M9, posađena 1998. godine na razmaku 3,0 x 0,8 m, a uzgojni oblik je bio vrlo vitko vreteno. Pokus je postavljen na nagnmutom terenu i na zaravni. U proljeće 2003. godine krošnje su pomoću oznake (bojom) podijeljene na gornju i donju polovinu. Rezultati istraživanja pokazali su značajan utjecaj staništa i položaja plodova u krošnji na vanjske i unutrašnje parametre kakvoće plodova. Na lošijem položaju (zaravan) postignut je manji prirod i manji udio plodova prve klase. Na obadvije lokacije dobiveni su plodovi bolje kakvoće u gornjem dijelu krošnje.
Canopies of 'Fuji' apple trees, grafted on M.9 rootstock, planted in 1998 on two orchard sites at 3.0 x 0.8 m and trained as super spindles, were subdivided in the spring of 2003 into upper and lower part. In each part the number of fruits, yield per tree, external (fruit size classes, fruit colouring) and internal (soluble solids content, titratable acid content, flesh firmness, starch degradation pattern) fruit quality attributes were determined. The orchard site parameters affected yield and fruit quality in different ways. The less suitable orchard site caused lower yield per tree and lower portion of 1st
class fruits. The favourable orchard site produced higher yield and higher portion of 1st class fruits. In the lower part of the canopy at both orchard sites, fruits were of a good size but poorly coloured. Fruits of the best quality were obtained from the top part of the
tree.

Istraživani su optimalni rokovi berbe za sorte Cripps Pink, Granny Smith i Fuji tijekom dvije godine u ekološkim uvjetima ušća rijeke Neretve. Plodovi su ubrani u nasadu jabuka u tri roka berbe, u vegetacijskoj godini 2006. i 2007., s razmakom od sedam dana između rokova. Pomoću standardnih metoda za određivanje optimalnog roka berbe jabuka u laboratoriju su provedene sljedeće analize: određivanje mase plodova, tvrdoće, topljive suhe tvari, ukupnih kiselina, proveden je škrobni test i utvrđen indeks dozrelosti.
Analizom dobivenih rezultata te usporedbom rezultata s relevantnom znanstvenom literaturom za istraživano područje utvrđeni su optimalni rokovi berbe za pojedine sorte. Za sortu Cripps Pink optimalni rok berbe bio je treći, (214 dana od pune cvatnje do
berbe), za sortu Granny Smith razdoblje oko drugog roka (201 dan od pune cvatnje do berbe), te za sortu Fuji drugi rok berbe (201 dan od pune cvatnje do berbe).
Researches were done to determine the optimum harvest time for apple cultivars: Cripps Pink, Granny Smith and Fuji, located in the Neretva river delta. There were three terms of getting samples with 7 days between each of them. Using some standard methods to determine optimum harvest time for apple yields, a few
laboratory analyses were done, such as: determination of firmness, soluble solids content, starch test, total acids and F/RS
After comparing our results with those from the literature were established for optimum harvest terms: for Cripps Pink it was the third (214 days after full bloom ), for Granny Smith the second (201 days after full bloom) and for Fuji it was the second (201 days after full bloom) term of harvesting.

Rasprostranjenost roda Vaccinium u Hrvatskoj
Distribution of the genus Vaccinium in Croatia

Vaccinium; flora; natural populations; genetic variability, Croatia
Rod Vaccinium obuhvaća relativno velik broj vrsta no u Hrvatskoj su nativne samo tri svojte (V. myrtillus L., V. vitis-idaea L. i V. uliginosum L.), dok je V. corymbosum L. ‘pridošlica’ koja svoju
nazočnost u flori Hrvatske zahvaljuje uvozu sadnog materijala i početku kultiviranja borovnice. U Hrvatskoj je svakako najraširenija vrsta V. myrtillus (borovnica) od koje se sakupljaju bobice koje se kao sezonsko šumsko voće još uvijek može naći na našim tržnicama. U narodu, prije relativno nepoznata V. vitis-idaea (brusnica) posljednjih godina postala je zanimljiva zbog pripisivanih joj povoljnih učinaka na zdravlje i velike propagande farmaceutske industrije. Kao što je to slučaj s mnogim drugim samoniklim vrstama voća na području Hrvatske, tako se ni u slučaju roda Vaccinium nije provodilo sustavno istraživanje rasprostranjenosti vrsta, ali se iz velikog broja pojedinačnih navoda i opažanja ipak može sastaviti prilično dobra slika njihove rasprostranjenosti. Isto tako, kod nas se nije provodio nikakav rad na oplemenjivanju i uvođenju u kulturu naših autohtonih vrsta. Zato je potrebno nastaviti istraživanjima rasprostranjenosti te istovremeno početi stvarati kolekcije jedinki s pozitivnim svojstvima da se olakša daljnji istraživački rad i oplemenjivanje.
The genus Vaccinium comprises a relatively large number of species, but in Croatia only three taxa are native (V. myrtillus L., V. vitis-idaea L. and V. uliginosum L.); the species V. corymbosum L. is a ‘newcomer’ in the Croatian flora thanks to imported plant material and to the beginning of blueberry cultivation. The most expanded species in Croatia is certainly V. myrtillus (blueberry) whose berries are gathered seasonally as wild fruits. This fruits can still be found on local fruit and vegetable markets. Unlike the previously mentioned species, V. vitis-idaea (cranberry) was rather unknown. In the few
past years, it has become interesting owing to its beneficial effects to human health, and the large advertising campaign undertaken by pharmaceutical industry. Systematically the research on the genus Vaccinium species distribution has not been carried out, and so is the case with many others wild growing fruit species in Croatia. However, because of a number of individual citations and observations, it is possible to get a quite good idea of their distribution. There have been no breeding programs or introduction of our native Vaccinium species to production which is the reason why further research on
their distribution is required. At the same time, collections of live native plant specimens with superior traits should be established to facilitate further research and breeding.

U radu se analiziraju proizvodni kapaciteti i proizvodnja sadnog materijala masline u RH, zakonodavni okvir i mjere potpore ovoj proizvodnji te tehnološki aspekt proizvodnje sadnog materijala masline u kontekstu izazova pred kojima se nalazi hrvatsko maslinarstvo i maslinarsko rasadničarstvo kao njegov sastavni dio u procesu pristupanja Europskoj uniji. U Hrvatskoj postoji 18 matičnih nasada masline i djeluje 20 registriranih poslovnih subjekata koji proizvode sadnice masline. U matičnim nasadima umatičeno je 3705
stabala od 26 sorti masline. Proizvodnja sadnica masline od 2000. do 2006. godine bilježi neprekidan porast te je u 2006. godini proizvedeno 575.881 sadnica maslina od 22 sorte, a u svim godinama
proizvedeno je najviše sadnica sorte Oblice. U okviru raspoloživih proizvođačkih kapaciteta postoji potencijal za dodatno povećanje domaće proizvodnje. Metoda orošavanja danas je dominantna metoda proizvodnje sadnog materijala masline u svijetu i Hrvatskoj. Metodom orošavanja u Hrvatskoj se proizvodi 90% od ukupnog broja sadnica masline, a domaći proizvođači primjenjuju je u skladu s tehnološkim standardima.
In this article production capacity and production of nursery olive trees in Croatia are analysed . Legal directives as well as measures of support for this production are also analysed. In the Republic of Croatia there are 18 orchards of olive mother trees and twenty
nurseries. The orchards of olive mother plants include 26 cultivars and 3705 olive trees. Nursery production in the period between 2000 and 2006 rose and in the year 2006 achieved 575881 nursery trees (22 cultivars), and the predominant cultivar was Oblica.
There are potentials for production increase. Mist propagation is today a dominant method of nursery olive tree production in
Croatia and in the world. In Croatia the production of nursery olive plants by this method is about 90% of total production.

Morphological and physical characteristics of three hazelnut (Corylus avellana L.) varieties (‘Istrska dolgoplodna leska’, ‘Tonda gentile delle langhe’ and ‘Fertile de coutard’) were examined in the trial to determine the parameters of the machine for mechanical crushing of hazelnuts. Three morphological characteristics (height, diameter and mass) and three physical characteristics (force, shell deformation and energy impact for shell crushing) were measured on the laboratory device. The maximum force (367.04 N) for crushing hazelnut shells by the diameter was measured with ‘Istrska dolgoplodna leska’, while for crushing by the height the maximum force was determined with the ‘Fertile de coutard’ variety (526.15 N). The biggest shell deformation in crushing by the height (1.00 mm) as well as by the diameter (1.11 mm) was measured with ‘Istrska dolgoplodna leska’. The most energy for crushing the shell by the nut height was required by ‘Fertile de coutard’ (0.24 J), while for crushing the shell by the diameter 0.22 J the most energy was spent by ‘Istrska dolgoplodna leska’. According to the morphological and mechanical characteristics of the shell, the ‘Istrska dolgoplodna leska’ variety was suggested to be the most suitable for mechanical crushing.
U pokusu usporedbe morfoloških i fizikalnih svojstava ploda lijeske (Corylus avellana L.) uključene su sorte: 'Istrska dolgoplodna leska', 'Tonda gentile delle langhe' i 'Fertile de coutard'. Pomoću izmjerenih morfoloških osobina: veličina ploda po promjeru i visini te masa ploda; i fizikalnih količina: sila, deformacija ploda i potrebna energija za lom ljuske ploda analizirana je mogućnost strojnog lomljenja ljuske. Maksimalna sila (367,04 N) za lomljenje lješnjaka po promjeru izmjerena je kod sorte 'Istrska dolgoplodna leska', a za lomljenje po visini kod sorte 'Fertile de coutard' (526,15 N). Najveća deformacija kod lomljenja lješnjaka izmjerena je po visini (1,00 mm) i promjeru (1,11 mm) kod sorte 'Istrska dolgoplodna leska'. Najveći utrošak energije za lomljenje lješnjaka po visini potreban je kod sorte 'Fertile de coutard' (0,24 J), a za lomljenje ljuske po promjeru lješnjaka kod sorte 'Istrska dolgoplodna leska' (0,22 J). Na temelju morfoloških i fizikalnih svojstava za strojno lomljenje najpovoljnija je sorta 'Istrska dolgoplodna leska'.

Ekologija Ravnih kotara za uzgoj kinesko - japanskih sorti šljiva
The ecology of Ravni kotari for growing Chinese - Japanese plum cultivars
Anđelko Vrsaljko
Ravni kotari sa svojim ekološkim karakteristikama, odnosno tlima, klimom i reljefom na osojnim padinama zadovoljavaju potrebe ekoloških čimbenika za uzgoj japansko – kineskih šljiva. Istraživanja fenologije cvatnje u pokusnim nasadima pokazuju da se fenologija cvatnje dijelom poklapa s cvatnjom ranijih sorata bresaka i nektaarina, odnosno općenito da je 3 do 4 dana ranija. Tako se cvatnja gospodarski najvrjednijih sorata, kao Black Gold i Black Diamond poklapa s cvatnjom breskve Mycrest (polovica ožujka). Ove sorte su zanimljive utoliko više što dospijevaju u srpnju u jeku turističke sezone, kada je velika potražnja za tim voćem. Širenje kinesko - japanskih sorata nije u većoj mjeri zaživjelo, što možemo pripisati problemima agronomskog i patološkog tipa. Osim poznatih poteškoća prilagodbe ovih sorata klimatskom podneblju Ravnih kotara, tu su i pojave nekih endemskih patogena kao Xanthomonas spp., što kompromitira rodnost i kakvoću plodova, te leptonekroza koja uzrokuje propadanje i uginuće stabala nakon par godina učestalog pojavljivanja, što nije slučaj kod europskih sorata. Nažalost, malo je sorata iz ove grupe i to uglavnom sorte za svježu potrošnju, koje se mogu preporučiti za širi uzgoj. Daljnjim istraživanjima bioloških i gospodarskih svojstava ovih sorata, biologije patogena, introdukcijom novijih sorata, te prikladne agrotehnike i adekvatne zaštite, moći ćemo potaći širenje provjerenih sorata na području Ravnih kotara i cijelom priobalju.
Ravni kotari with its ecological characteristics, respectively climate and relief on the shady slopes satisfy the needs of the ecological factors for growing Chinese - Japanese plums. The researches of the blossoming phenology in the experimental orchards, show that the blossoming phenology partially correspond to the blossoming of earlier types of peaches and nectarines, respectively 3 to 4 days earlier. That is why the blossoming of the economically most valuable types, like Black Gold and Black Diamond corresponds to the blossoming of the peach Mycrest (middle of March). These cultivars are interesting because they mature in July, at the height of the touristic season, when there is a great demand for this fruit. The spreading of Chinese - Japanese cultivars has not been significant, which can be attributed to problems of agronomic and pathological types. Excepting the known difficulties of adaptation of these species to the climate of Ravni kotari, there are the endemic pathogens like Xanthomonas spp. which compromises the fruit fertility and quality, and leptonecrosis which causes the decline and the death of the trees after several years of frequent appeareance, and this is not the case of the European cultivars. Unfortunately, there are few sorts from this group, mostly specie for fresh comsumption recommendable for expanded cultivation. With further reseraches on biological and economic characteristics of these cultivars, the biology of pathogens together with the introduction of new cultivars, the adequate agrotecnics and protection, will be able to stimulate the expansion of verified cultivars in Ravni kotari and the entire coastal area.

Production systems in southern Europe: huelva (Spain
Sustavi proizvodnje u južnoj Europi: Huelva (Španjolska)

Strawberry; Raspberry; Blueberry; Huelva (Spain)
jagoda; malina; borovnica; Helva (Španjolska)
The strawberry is one of the most important crops in the Province of Huelva, south western Spain. More than 90% of the national production is harvested in this area, which means over 35% of the total production of the EU. During the 2007-2008 season, the acreage used for that crop was estimated at over 6.000 ha, and the production of 240.000 tons. The most widely used strawberry cultivar was ‘Camarosa’ (70%) followed by ‘Candonga’ (12%), with lower yields but better fruit quality, ‘Festival’ (12%), ‘Ventana’ (2%) and other minor varieties like ‘Chiflón’, ‘Aguedilla’ and ‘Coral’. The raspberry crop acreage for the 2007-2008 season has been estimated at around 1.330ha, increasing over 2.5% compared to the previous season. Most plants used to set the crop are multiplied in low elevation nurseries within the same area of the production fields, and only a small amount of plants come from high elevation nurseries in the north of Spain. The most common cultivar used is ‘Glen-Lyon’, with more than 90% of the acreage under the crop. The development of the blueberry crop in Huelva has also been important for the area during the last five years. Currently, more than 750 ha are used for the crop, but only 26 ha are in ecological production, and 90% of this acreage, is located in the village Almonte. 95% of the blueberry production is exported to Germany, United Kingdom, Belgium, the Netherlands and Switzerland. Early-season yield cultivars like ‘Misty’, ‘Sharpblue’ and ‘O`neal’ are widely used (70%) but also mid-season yield cultivars, like ‘Star’, can be found in the area. The export marketing season starts in February and lasts until June, but market picks are usually found in April, May and June. Each cultivar presents a different harvest season which period can take more than 45 days.
Jagoda je jedan od najvažnijih usjeva u pokrajini Huelva, jugozapadna Španjolska. Više od 90% nacionalne proizvodnje dobiva se na tom području, što znači preko 36% ukupne proizvodnje EU. U sezoni 2997-2008. površina namijenjena tom usjevu procijenjena je na preko 6,000 ha a proizvodnja na 240.000 tona. Najviše upotrebljavan kultivar jagode bio je Camarosa (70%), a slijedili su Candonga (12%) manjih prinosa ali bolje kakvoće voća, zatim Festival (12%) Ventana (2%) te druge manje varijante kao Chiflon i Coral. Površina malina za 2007-2008 procijenjena je na oko 1.330 ha s povećanjem preko 2.5% u usporedbi s prethodnom sezonom.Većina biljaka za nasade se razmnaža u rasadnicima niskog rasta unutar područja proizvodnih nasada i samo malen broj biljaka dolazi iz rasadnika biljaka visokog rasta na sjeveru Španjolske. Najčešći kultivar je Glen-Lyon s više od 90% površina. Razvoj nasada borovnice u Helvi također je važan za to područje zadnjih pet godina.Trenutačno više od 750 ha pokriva ova kultura ali samo 26 ha je pod ekološkom proizvodnjom a 90% te površine nalazi se u selu Almonte. U Njemačku, Ujedinjeno Kraljevstvo, Belgiju, Nizozemsku i Švicarsku izvozi se 95% proizvodnje borovnica. Rani kultivari kao Misty, Sharpblue i O Neal naširoko se upogrebljavaju (70%) ali isto tako i kultivari koji dozrijevaju sredinom sezone kao Star mogu se naći u ovom području. Sezona izvoza počinje u veljači i traje do lipnja,ali branje za trgovinu obično se odvija u travnju, svibnju i lipnju.Svaki kultivar ima drugačiju sezonu branja a to razdoblje može trajati 45 dana. )

Strawberry Production Systems in France
Jagoda, proizvodni sustavi u Francuskoj
J-P BOSC
France; production systems; strawberry
Francuska; proizvodni sustavi; jagoda
Strawberry has been a traditional culture in France for nearly three centuries. National production greatly decreased over the past fifteen years: from 82,000 T between 1990 and 1995, to 46,900 T in 2007. In the last five years, the surface regularly decreased from 3,780 ha in 2002 to 3,265 ha in 2007. The import/export balance shows a high deficit: more than 110,000 T are imported yearly, mainly from Spain and Morocco. Nearly all the production goes to the fresh consumption; only a very small percentage (1,300 T in 2007) is processed. Half the French production is sold between the end of April and early June, but the general picking period starts mid-February and ends in the first week of November. Four main areas totalise ¾ of the national production: South-West (39% in 2007), South-East (14%), Rhône-Alps (14%), and Loire Valley (11%). French national production is nowadays focused on quality and high prices, mostly based on French Junebearing cultivars (‘Gariguette’, ‘Darselect’), with a minor everbearer production during summer (‘Mara des Bois’, Charlotte’). Within thirty years, production systems moved from dominant open field system to dominant high tunnel systems, and to a lesser extent glasshouses (high tunnel glasshouses: 62% of the total surface in 2007). Open field and small tunnels are strongly decreasing each year, while high tunnels are increasing. Substrate culture in high tunnels and glasshouse is now estimated at about 400 ha, and is still increasing. The substrate culture enables the growers to produce “ten months a year”, while combining cultivars, type of plants and heating. New challenges for national production are pest and disease control, and labour costs. French production systems clearly evolve to more technical crop management, with tasty cultivars, to differentiate from cheaper imported strawberries.
Jagoda je tradicionalna kultura u Francuskoj već skoro tri stoljeća. Nacionalna proizvodnja se uvelike smanjila zadnjih petnaest godina: od 82,000 t 1990. do 1995. na 46,000 t 2007. Zadnjih pet godina površine su se smanjile od 3,780 ha 2002. na 3.265 ha 2007. Uvozno/izvozna bilanca pokazuje veliki deficit: više od 110,000 t se uvozi godišnje, uglavnom iz Španjolske i Maroka. Gotovo sva proizvodnja ide u svježu potrošnju;samo vrlo malen postotak (1,300 t u 2007.) se prerađuje.Polovica francuske proizvodnje prodaje se između konca travnja i početka lipnja, ukupno razdoblje branja počinje sredinom veljače i završava u prvom tjednu studenog. Četiri glavna područja čine 3/4 nacionalne proizvodnje: jugozapad (39% 2007'), jugoistok (14%) Rona-Alpe (11%) i Dolina Loire (11%). Francuska nacionalna proizvodnja je danas usmjerena na kakvoću i visoke cijene, većinom temeljena na francuskim kultivarima koji dozrijevaju u lipnju (Gariguette, Darselect), s manjom proizvodnjom jagoda koje stalno rode za vrijeme ljeta (Mara des Bois, Charlotte). U trideset godina proizvodnja se pomaknula iz dominantnog sustava otvorenog polja na dominantan sustav visokog tunela, te u manjoj mjeri staklenike (staklenici visoki tuneli: 62% ukupne površine 2007.). Otvorena polja i mali tuneli veoma se smanjuju svake godine, dok visoki tuneli rastu.Kultura supstrata u visokim tunelima i staklenicima sada se procjenjuje na oko 400 ha i još uvijek raste. Kultura supstrata omogućuje uzgajačima proizvodnju deset mjeseci u godini. Istovremeno kombinirajući kultivare, vrstu biljaka i grijanje. Novi izazovi u nacionalnoj proizvodnji su suzbijanje nametnika i bolesi, te troškovi rada. Francuski sustavi proizvodnje očito se razvijaju prema više tehničkom ujpravljanju usjevima, s ukusnim kultivarima za razliku od jeftinijih uvoznih jagoda.

jagoda; malina; kupina; sustavi proizvodnje
The most important small fruit crop is that of strawberry and all others (raspberries, blackberries, currants, blueberries) are considered minor crops. The strawberry production/year accounts for 25 000 tons and all others produce up to 1000 tones. The main system in strawberry culture is raised beds in walks in tolls (4 rows/toll), for ‘off season’ production and the most important strawberry variety is ‘Camarosa’. Raspberry and blackberry plants are mostly trained in hedgerow systems. The most important raspberry varieties are: ‘Autumn Bilss’, Heritage, ‘Meeker’ and ‘Glen Lion’. Regarding blackberries the most important varieties are: ‘Silvan’, ‘Kotata’, ‘Choctaw’, ‘Comanche’, ‘Cherokee’, ‘Black Satin’, ‘Hull Thornless’, ‘Thornless Evergreen’, ‘Chester’ and the hybrid ‘Tayberry’. Most of the planting material is imported. Recently there is increasing interest in blueberry production due to potentially health benefit effects.
Najvažnija kultura sitnog voća je jagoda a sve druge (malina, kupina, ribiz borovnica) smatraju se manje važnim kulturama. Proizvodnja jagoda/godina iznosi 25.000 tona a sve ostalo iznosi do 1000 tona.Glavni sustav uzgoja jagoda su podignute gredice između staza, za proizvodnju "izvan sezone" a najvažniji kultivar je Camarosa. Biljke malina i kupina većinom se uzgajaju u sustavu živice. Najvažniji varijeteti maline su Autumn Bliss, Heritage, Meeker i Glen Lion. Najvažniji varijeteti kupina su Silvan, Lotata, Choctaw, Comanche, Cherokee, Black Satin, Hull Thornless, Thornless Evergreen, Chester, te hibrid Tayberry. Većina sadnog materijala se uvozi.U zadnje vrijeme poraslo je zanimanje za proizvodnju kupina zahvaljujući mogućem povoljnom djelovanju na zdravlje.

Turkey is one of the most significant countries in the world from the point of view of both fruit genetic resources and amount of fruit production. Around 100 fruit species, including almost all the deciduous fruit species, most of the subtropical and some tropical fruit are grown in Turkey. Among fruits, berry fruits including grapes share 25% of total fruit production of the country. The most important berry fruits in terms of amount of production in Turkey after grape are strawberry (average 200.000 tons production annually) and followed by mulberry (70.000 tons), raspberry and blackberry (30.000 tons) and blueberry (5000 tons).
Mulberries are cultivated throughout Turkey but they are more common in Northeast, Southeast and Central Anatolia between 0 to 1500 m above sea level. The country is represented by four mulberry species, namely Morus alba, Morus nigra, Morus rubra and Morus laevigata. Mulberry trees are grown only for fruit production in Turkey compared to the other main mulberry production countries such as India, China etc. which use mulberry trees for leaf yield in sericulture. The interest in growing mulberries is increasing year by year in Turkey. The Black Sea Region of Turkey, northeastern part of Anatolia, is one of the main germplasm centers of several Vacciniums and Ericaceous plant species. Caucasian whortleberry (Vaccinium arctostaphylos), bilberry (Vaccinium myrtillus) and lingonberry (Vaccinium vitis-idea) have been naturally grown in the forests and plateaus over the centuries. However commercial blueberry production by using northern high bush blueberries started in the 2000s in the country.
Turska je jedna od najznačajnijih zemalja na svijetu sa stajališta genetskih izvora voća i proizvodnje voća. U Turskoj se uzgaja oko 100 vrsta voća uključujući gotovo sve bjelogorične vrste, te većinu suptropskog i nešto tropskog voća. Među voćem, bobičasto voće, uključujući grožđe, iznosi 25% ukupne proizvodnje voća u zemlji. Najvažnije bobičasto voće u smislu količine proizvodnje iza grožđa su jagode (prosječna godišnja proizvodnja 200,000 tona). Dud se uzgaja po čitavoj Turskoj ali je češći na sjeveroistoku, jugoistoku i središnjoj Anadoliji između 0 i 1500 m iznad razine mora. Zemlju predstavljaju četiri vrste duda: Morus alba, Morus nigra, Morus rubra i Morus laevigata. U Turskoj se dudovo drveće uzgaja samo radi proizvodnje voća u usporedbi sa zemljama-glavnim proizvođačima duda kao što su Indija, Kina itd. koje upotrebljavaju drveće duda za lišće radi proizvodnje svile. Interes za uzgoj duda u Turskoj raste iz godine u godinu. Područje Crnog mora,sjeveroistočni dio Anadolije, jedno je od glavnih centara germplazme nekoliko vrsta Vacciniums i Vericaceous biljaka. Kavkaska borovnica (Vaccinium arctostaphylos), borovnice (Vaccinium myrtillus i Vaccinium vitis-idea) prirodno rastu u šumama i na visoravni već stoljećima. Međutim, komercijalni uzgoj borovnice primjenom visoke grmolike sjeverne borovnice započeo je 2000. godine ovog stoljeća.

Višegodišnjim istraživanjima biljno-hranidbenog kapaciteta tla metodom folijarne dijagnoze u plantaži jabuka Borinci na antropogenom eutričnom smeđem tlu na karbonatnom lesu u semiaridnom području istočne Slavonije utvrđene su genetske,
odnosno sortne specifičnosti, mineralne ishrane. Istraživanja su obavljena u plantaži Borinci kraj Vinkovaca na 5 do 11 godina starim stablima sorata: Golden Delicious, Gloster, Melrous, Idared, Red Boskoop, Jonagold i Jonathan, cijepljenim na podlozi M9. Jabuke su dostatno opskrbljene dušikom i kalijem, a optimalno fosforom,kalcijem i magnezijem. Veće variranje utvrđeno je u koncentraciji dušika i kalija. Genetske, odnosno sortne specifičnosti odrazile su utjecaj na koncentraciju dušika, kalija i kalcija, dok je razina fosfora i magnezija uglavnom podjednaka u lišću svih istraživanih sorti. Najveću koncentraciju dušika sadrži lišće sorte Gloster, a najmanju sorte Golden Deliciou. Signifikantna je razlika između ove dvije sorte i u njihovu odnosu na ostale sorte. Podjednaku koncentraciju dušika sadrži lišće skupine sorti Melrous, Jonagold i Jonathan, kao i u skupine sorti Idared i Melrous. Utvrđena je signifikantna razlika između dvije skupine sorti. Veću koncentraciju kalija ima lišće sorte Melrous od ostalih sorti. Razlika je signifikantna. Manju koncentraciju kalija sadrži lišće sorti Gloster,
Idared i Jonathan od sorti Golden Delicious i Jonagold. Razlika je statistički opravdana. Signifikantno nižu koncentraciju kalcija sadrži lišće sorte Melrous od ostalih soreti. Signifikantno veću koncentraciju kalcija sadrži lišće sorata Golden Delicious, Gloster, i Idared od sorata Jonagold i Jonathan.
Investigations of the plant feeding capacity of the soil using foliar diagnosis method on apple plantation on antropogenous brown soil on calcareous loess were carried out over the period of six years in the eastern Croatia for determination of genetic, i.e. cultivar features of mineral nutrition. The investigations were carried out on the
plantation of the Borinci near Vinkovci on 5 to 11 year old trees in the cultivars: Golden Delicious, Gloster, Melrous, Idared, Red Boskoop, Jonagold and Jonathan grafted on rootstock M9. Apples are sufficiently supplied with nitrogen and potassium, and optimal supply of phosphorus, calcium and magnesium. Greater variations were
determined in concentrations of nitrogen and potassium. Genetic and variety specificity has reflected its influence to concentration of nitrogen, potassium and calcium while levels of phosphorus and magnesium are rather equal in leafs of investigated cultivars.
The level of nitrogen was the highest in the leaves of cv. Gloster and the lowest in cv. Golden Delicious. There is a significant difference between these two cultivars and in their relation to other cultivars.
Equal concentrations of nitrogen are determined in leafs of cultivars Melrous, Jonagold and Jonathan, as well as in cultivars Idared and Melrous. Significant difference is determined between two groups of cultivars. The concentration of potassium was higher in leafs of cultivar Melrous than in leafs of other cultivars. The difference is significant. The concentration of potassium was lower in leafs of cultivars Gloster, Idared and Jonathan than in leafs of cultivars Golden Delicious and Jonagold. The difference is statistically justified. Significantly lower concentration of potassium was found in leafs of cultivars Gloster, Idared and Jonathan than in cultivars Golden
Delicious and Jinagold. The difference is statistically justified. Leafs of cultivar Melrous have significantly lower concentration of calcium than other cultivars. Significantly higher concentration of calcium was found in leafs of cultivars Golden Delicious, Gloster and Idared than in cultivars Jonagold and Jonathan.

The influence of hot steam vaporization of the walnut (Juglans regia L.) cultivar 'Franquette' on the required force for deformation (breaking) and the energy required to fracture the shell with the centrifugal breaking machine was studied under the laboratory conditions. The maximum force (248.04 N) was used for breaking nuts, which were vaporized for 5 minutes and 171.35 N for 15 minutes vaporized samples of nuts. The shortest deformation (1.3 mm) was measured for breaking 0 minute vaporized nuts, and the maximum deformation (4.15 mm) for 15 minutes vaporization samples. The largest percent of the whole kernels (74.62 %), was measured on 15 minutes vaporized nuts and the lowest on 0 minutes vaporized sample (28.47 %).
U pokusu usporedbe morfoloških i fizikalnih svojstava ploda oraha (Juglans regia L.) sorte 'Franquette' proučavan je utjecaj parenja vručom parom na potrebnu silu za deformaciju (lomljenje) ploda te potrebnu energiju za lom ljuske ploda pomoću centrifugalnog stroja za lomljenja. Maksimalna sila (248,04 N) za lomljenje oraha
izmjerena je kod 5 minuta parenih uzoraka, a najmanja kod 15 minuta parenja (171,35 N). Najmanja deformacija (1,3 mm) izmjerena je kod lomljenja suhih oraha, a najveća kod 15 minuta parenih (4,15 mm). Najveći dio celih jezgri (74,62 %), dobiven je kod
lomljenja 15 minuta parenih oraha a najmanji kod 0 minuta parenja (28,47 %.).

Maslinarstvo u Istri ima višestoljetnu tradiciju. Mnogi arheološki nalazi upućuju na zaključak da su se masline uzgajale u Istri i prije dolaska Rimljana. Agroekološki uvjeti u Istri predstavljaju rubno sjeveroistočno područje rasprostranjenosti masline, i kao takav predstavlja specifičan areal uzgoja tipičnih sorti maslina. U Istri ima oko tridesetak sorata maslina, a donešene su ovamo u više navrata,
neke prije nekoliko tisuća godina, a druge pred nekoliko stotina godina. U našem je istraživanju bilo uključeno 20 uzoraka stabala masline istarske sorte Rosinjola na nekoliko lokacija na području Rovinja. Na osnovi istraživanja upotrebom morfoloških metoda identifikacije opisane su morfološke karakteristike listova, plodova
i endokarpa po metodologiji za primarnu karakterizaciju sorata masline prema IOC-u.
Olive growing in Istria has a several century long tradition. Many archeological findings refer to conclusion that the olives were cultivated on Istrian territory before the arrival of Romans.
Agroecological conditions in Istria represent the northeast edge distribution of olive, and like this it represents a specific cultivation areal of typical olive's varieties. In Istria there are about thirty olive's varieties which have been brought here in more occasions, some several thousand years ago, others several hundred years ago.
Our survey included 20 samples of olive's tree of Istrian variety Rosinjola on several locations on the territory of Rovinj. Based on research which included the use of morphological methods of identification there are described the morphological characteristics of leaves, fruits and stones according to Methodology for Primary
Characterisation of Olive Varieties in accordance with International Olive Council (IOC).

Pomološka svojstva sorata šipka uzgajanih na području zapadne Hercegovine
Pomological properties of pomegranate cultivars growing on the area of west Herzegovina
Ivan Marinović
Dijana Vego
Na području zapadne Hercegovine obilaskom lokaliteta izdvojeno je sedam sorata šipka: Karaderviš, Majdeški sitnozrni, Slatki barski, Glavaš, Šerbetaš, Paštrun, Konjski zub. Opisana su slijedeća svojstva: vrijeme zrelosti plodova, procjena rodnosti, prosječna težina plodova, oblik plodova, izraženost rebara, boja kore, debljina kore te ispunjenost ploda zrnjem kao jedno od najvažnijih pomoloških svojstava. Nadalje je zabilježena boja, veličina, sočnost zrnja i okus soka. Istraživane sorte se posebice razlikuju u vremenu dozrijevanja, težini ploda, randmanu zrnja, okusu soka i
rasprostranjenosti. Ove razlike su posljedica genetskog potencijala sorte, ali i različitih uvjeta uzgoja.
Seven cultivars are separated by rounding of region on the area of west Herzegovina: Karaderviš, Majdeški sitnozrni, Slatki barski, Glavaš, Šerbetaš, Paštrun, Konjski zub. Following properties are described: time of fruit maturity, estimate of fruitset, the average fruit weight, occurrence of the ribs, bark-color, thick of the bark, than
fruit filling by grains as one of the most important pomological property. Further was recorded the color, size, succulence of the grains and juice-taste. Investigated cultivars are different especially in time of ripening, fruit weight, gains yield, juice-taste and their
spreading. These differences are result of the genetic potential of cultivar, as well as different growing conditions.

REFORM OF THE EU COMMON MARKET ORGANISATION FOR FRUIT AND VEGETABLES
Jasna Čačić
Dražen Čačić
Jasenka Gajdoš Kljusurić
European Union; common market organisation; fruit and vegetables; legislation; Croatia
A new Common Market Organisation (CMO) for fruit and vegetables is in place from 1 January 2008. First debate about reform was lunched in 2004 by European Commission and its publication about simplification of the Fruit and Vegetable Common Market Organisation. The last extensive reform in 1996 introduced modifications like a plan for the progressive reduction of support for short-term market intervention and the strengthening of structural aid to improve competitiveness in order to help producers to
develop their capacity and to adapt to market demand. The most important reasons for the new reform of CMO for fruit and vegetables are imbalance in the supply and distributions chain, limited influence of the producers’ organisations, coherence with
rural development aid and the questions of standards. The objective of this paper is to explore the regulatory framework of the European
Common market organisation for fruit and vegetables, reasons and aims of the reform and to compare the Croatian legislation regarding fruit and vegetables sector with the EU CMO for fruit and vegetables.
The qualitative research strategy which emphasizes words rather than quantification in the collection and analysis of data and has an inductive approach to the relationship between theory and research is used to make conclusions in this paper. The conclusions
about the objectives are made by studying the reference literature related to the topic of the EU Fruit and Vegetables Common market organisation, assumptions derived from the research and professional knowledge related to the topic.

'Tugarka' je najzastupljenija sorta trešnje u mediteranskom dijelu Hrvatske. Jedan od uzroka njene neredovite rodnosti je loš uspjeh oprašivanja s inkompatibilnim sortama prisutnim u nasadima. Analizirana je uspješnost zametanja plodova nakon
samooprašivanja, stranooprašivanja i slobodnog oprašivanja sorte Tugarka, te su izdvojeni njeni najbolji oprašivači. U ulozi oprašivača, u istraživanje su uključene sorte Lambert compact, Bing spur, Van compact i višnja maraska 'Poljička', koje su istovremeno cvjetale sa glavnom istraživanom sortom. Uspjeh klijavosti polena
analiziran je metodom viseće kapi u 12% otopini saharoze pri temperaturi od 22ºC. Klijavost polena sorti oprašivača zabilježena je u rasponu od 35% ('Van compact') do 41.04% ('Bing spur'). Zbog izostanka zametanja plodova nakon samooprašivanja 'Tugarka' je opisana kao autoinkompatibilna sorta. Značajno najveći uspjeh zametanja plodova kod sorte Tugarka zabilježen je nakon oprašivanja sa sortom Lambert compact (22.5%), a najmanji nakon oprašivanja sa višnjom maraskom 'Poljička' (14.2%).
'Tugarka' is most presented cultivar grown in orchards of Mediterranean part of Croatia. Inadequate pollination caused irregular yield of that valuable cultivar. The aim of this study was to determinate the success of self-pollination, cross-pollination and
free-pollination of 'Tugarka', and to define its best pollenizer(s). Cultivars used as pollen donors, 'Lambert compact', 'Bing spur', 'Van compact', and sour cherry marasca 'Poljička', were selected according to their simultaneous flowering period with 'Tugarka'. Pollen germination of tested cultivars was determined in 12% sucrose
solution at 22ºC using hanging drop technique. Controlled pollinations with pollen of each pollenizer were carried out during the full bloom. Fruit set following selfpollination, cross-pollination and free-pollination was analysed just before the harvest. Pollen germination rates varied from 35% ('Van compact') to 41.04% ('Bing spur'). Absence of fruit set following self-pollination described 'Tugarka' as self-incompatible
cultivar. Significantly the best fruit set of 'Tugarka' was recorded after the pollination with 'Lambert compact' (22.5%), and the lowest following pollination with sour cherry 'Poljička' (14.2%).

Bactrocera oleae is the most importanat olive pest in Montenegro. The infestation is located only on the fruit and results in significant damage and for this reason, induces the neccessity for its control. Various control methods and applications of chemical substances are directed towards suppression of adults and have preventive character, therefore monitoring of abundance and flight dynamics is of high importance. Trials were set in olive plantation of Centre for subtropical cultures in Bar, on native variety Žutica, in three years period (the year of 2005, 2006 and 2007). Flight dynamics was monitored by chromotropic and pheromone traps of Dacotrap type,
during the period from July to the end of October in all years of monitoring. Traps were monitored once a week and the flight dynamics of fly is showen through the average abundance of females and males on chromotropic and pheromone traps. In the region of Bar, which is the biggest olive area in Montenegro seaside, olive fly
developes several generations during one year. Generations interleave with each other and therefore the fly is present in plantations, with different appearance intensity, from begining of July untill the middle of December, and in some years the flight lasts even
longer, so the presence of adults is also detected in January. The maximum abundance, reffering to the most intensive flight is during September and October. Chromotropic traps hold out a more precise evaluation of population abundance present in the plantation, while pheromone traps are very important in infestation forecast and
appropriate treatment timing determination.
Bactrocera oleae je najznačajniji štetnik masline u Crnoj Gori. Napada isključivo plod i pričinjava značajne štete, zbog čega se nameće potreba njenog suzbijanja. Različite metode suzbijanja i upotreba kemijskih sredstava usmjereni su na suzbijanje
imaga i imaju preventivni karakter, te je praćenje brojnosti i dinamike leta od izuzetnog značaja. Istraživanja su izvedena u zasadu masline Centra za suptropske kulture u Baru, na
autohtonoj sorti žutica, u trogodišnjem periodu (2004, 2005 i 2006. godine). Dinamika leta muhe masline praćena je pomoću hromotropskih i feromonskih lovki tipa Dacotrap, u periodu od srpnja do kraja listopada u svim godinama posmatranja. Pregled lovki
vršen je jednom tjedno, a dinamika leta muhe izražena je preko prosječnog broja ženki i mužjaka na hromotropskim i feromonskim lovkama. Na području Bara, koje je i najveće maslinarsko područje na crnogorskom primorju, muha masline razvije više generacija u tijekom godine. Generacije se međusobno preklapaju pa je muha u zasadima, sa različitim intenzitetom pojave, prisutna od početka srpnja do polovice prosinca, a pojedinih godina let traje i duže, pa se prisustvo imaga detektuje i u siječnju. Najveća brojnost, odnosno najintenzivniji let je tokom rujna i listopada. Hromotropske lovke nude precizniju procjenu brojnosti populacije prisutne u zasadu, dok su feromonske lovke veoma značajne za prognozu infestacije i
određivanje pravog momenta za tretiranje.

Analizirane su pomološke (širina i visina ploda, masa ploda i zrna, masa 100 zrna, randman zrna, sadržaj soka, debljina kore, visina i promjer čaške) i kemijske osobine ploda (suha tvar, ukupna kiselost, pH, sadržaj K+ i
NO3 - iona, ukupni i reducirajući šećeri) te boja zrna. Dobiveni rezultati pokazali su značajne razlike između istraživanih sorata. Sorta Glavaš ima veću masu ploda i zrna, veći sadržaj ukupnih kiselina, viši pH i veći sadržaj K+. Prema kemijskom sastavu obadvije sorte pripadaju skupini kiselih sorata te su pogodne za proizvodnju sokova.
The research has been conducted upon the authochthonous pomegranate species called Glavaš and Paštrun that were grown in West Hercegovina. The quality of the fruit was analysed by the pomological parameters (fruit width and lenght, fruit weight and
aril weight, 100 aril weight, randman of arils, juice content, peel thickness, calyx lenght and diameter) and chemical analyses (total soluble solids, titrable acidity, pH, K+ and NO3 - content) and
fruit skin colour. The given resultsshow that there were significant
differences between the cultivars. The 'Glavaš' fruits had the highest fruit weight, aril weight, titrable acidity, pH and K+ .The results imply that pomegranate cultivars Glavaš and Paštrun have sour taste and they are suitable for juice production.

Model točke pokrića je koristan analitički instrument za utvrđivanje ekonomskih učinaka koji pomaže u planiranju i donošenju poslovnih odluka u procesu upravljanja maslinarskom proizvodnjom. Ovaj model se koristi kao analitički instrument koji daje određene smjernice za kratkoročno poslovno odlučivanje. Cilj rada bio je primijeniti cjelokupnu analizu točke pokrića i pokazati odnose između troškova, prihoda i financijskog rezultata pri različitim razinama proizvodnje maslina te utvrditi razinu proizvodnje kod koje su pokriveni ukupni troškovi uz determiniranu prodajnu cijenu.
Na temelju tehnoloških i ekonomskih polazišta izrađena je modelna kalkulacija pokrića varijabilnih troškova maslinarske proizvodnje. Modelnom kalkulacijom utvrđeni troškovi i prihodi predstavljali su podlogu za analizu točke pokrića i izračunavanje relevantnih ekonomskih veličina i pokazatelja. Pri količini proizvodnje od
386 kg maslinovog ulja ostvaruje se ukupni prihod u iznosu od 17.391,59 kn koji pokriva ukupne troškove, što znači da je potrebno ostvariti 28,9% ukupne količine proizvodnje za izlazak iz zone gubitka. Pozitivan financijski rezultat i vrijednosti ekonomskih pokazatelja proizvodnosti rada, ekonomičnosti i rentabilnosti proizvodnje u analitičkom modelu pokazuju da je konvencionalna proizvodnja maslina u punoj rodnosti efikasna pod pretpostavkom postizanja očekivanog priroda ploda, randmana ulja i njegove uspješne prodaje.
The break-even model is an useful analytical instrument for determination of economic effects, which facilitates planning and business decision-making in the process of olive production management. This model is used as an analytical instrument
that provides specific guidance for short-term business decision-making. The paper aim was to apply the whole break-even analysis, show the relations between costs, revenues, and financial result at various olive production levels, and determine the production
level where total costs are covered with the determined selling price. Gross margin calculation model of olive production has been created on the basis of technological and economic starting points. Costs and revenues determined by model calculation were the basis for the break-even analysis and the calculation of relevant economic values and indicators. At the production of 386 kg of olive oil, the total
revenue of 17,391.59 HRK covers the total cost, which means that 28.9% total production should be realised so as to come out of loss. The positive financial result and the values of economic indicators of labour productivity, cost-effectiveness and profitability of production in the analytical model show that the conventional production
of olives in full fertility is effective under the assumption of realisation of the expected yield, the average yield of olive oil and the successful sales.
