Abstract
The fruit of the sweet chestnut (Castanea sativa Mill.) is most often used for the production of forest reproductive material for afforestation and reforestation, and as a food product. It is easily perishable and difficult to store without significant loss of viability.The aim of the study was to determine the qualitative properties and health status of sweet chestnut fruits and the detection of fungal and insect species before and during storage. The fruits were collected in the Forest Administration Požega in October 2007. The qualitative properties of the fruits according to ISTA Rules were analyzed. The germination was 40% and viability was 35%. The fruits were stored in PE bags in the refrigerator at a temperature of 3 to 5° C. After five months of storage, the health status of the fruits was analyzed. The analysis revealed a high percentage of infected fruits (60%) The fungi were determined by classical morphological analysis using macro and micro methods and molecular method. Eight species of pathogenic fungi and two species of insects were detected: Alternaria alternata (Fr.) Kisler, Aspergillus flavus Link., Aspergillus niger Tiegh, Ciboria batschiana (Zopf) Buchw., Penicillium spp., Phomopsis castanea (Saccichodide) Höhn, Tr. Pers., Trichothecium roseum Link., and Curculio elephas Gill., and Cydia splendana Hb.
