Abstract

The aim of this study was to assess the influence of application of mycorrhizal fungal inoculum on the Portugieser wine chemical composition. The experiment was conducted in fall 2016. in 3 locations in the area of ZOI Plešivica, with the „Mykoflor” vaccine of Bio-budućnost d.o.o company application. The vaccine was applied to 100 vines of Portugieser variety, with the same number of untreated vines as a control. Chemical composition analysis of wine, as well sensory evaluation was carried out after the harvest in 2018. The results obtained demonstrated the positive impact of mycorrhiza on the wine chemical composition as an increase in total acidity, individual organic acids, wine ash, as well as decrease in pH value. Mycorrhiza also had a positive effect on the wine polyphenolic composition and sensory evaluation.

Abstract

Cilj ovog istraživanja bio je utvrditi kako primjena živog mikoriznog cjepiva na korijen vinove loze utječe na kemijski sastav vina ´Portugizac´. Pokus je postavljen u jesen 2016. godine na 3 lokacije na području podregije Plešivica, kada je provedena i aplikacija cjepiva naziva „Mykoflor“ tvrtke Bio-budućnost d.o.o. Cjepivo je aplicirano na 100 trsova sorte ´Portugizac´, pri čemu je isti broj netretiranih trsova poslužio kao kontrola. Analiza kemijskog sastava, kao i senzorno ocjenjivanje vina provedeni su nakon berbe 2018. godine. Rezultati su pokazali pozitivan utjecaj mikorize na kemijski sastav vina u vidu povećanja koncentracije ukupne kiselosti, pojedinačnih organskih kiselina, pepela te smanjenja pH vrijednosti vina. Aplikacija mikoriznog cjepiva pozitivno je utjecala i na polifenolni sastav te na senzornu ocjenu vina.
