Preharvest microbial population of Indian jujube fruits (Ziziphus mauritiana Lamk.) and their implications in postharvest pathogenesis.

A mycological survey was carried out on the fruit surface of Z. mauritiana, in Jammu and Kashmir, India, during its growth period. A total of 32 microfungi belonging to 20 genera were isolated by surface washing. Artificial inoculations with the isolated propagules were also performed in mature Z. mauritiana fruits and most of them caused rot of varying severity. However, Monodictys castaneae, Eupenicillium lapidosum, Paecilomyces fumosoroseus, Trichurus spiralis and Acremonium spp., although present on the fruit surface, were not able to cause rot, indicating lack of specific macerating enzymes necessary for postharvest pathogenesis. The most frequently isolated pathogens were Aspergillus flavus, Emericella nidulans, Aspergillus niger, Alternaria alternata, Cladosporium oxysporum, Curvularia lunata [Cochliobolus lunatus], Fusarium sporotrichioides and Penicillium chrysogenum. It is concluded that a relationship exists between preharvest fungal populations and postharvest fruit rot of Z. mauriti
