Post-Harvest Mycoflora of Root Vegetables from Ad Darb Markets, Jizan, Saudi Arabia

This is the first study of post-harvest mycoflora of root vegetables from Ad Darb region of Jizan province. A total number of ten samples of root vegetables from the local markets of the place with post harvest spoilage fungi were collected and studied. The mycoflora was cultured on Potato Dextrose Agar plates. A qualitative and quantitative assessment of mycoflora was carried out by the fungal cultures on petri plates in triplicate and the slides were identified by microscopic and macroscopic characteristics. A total of 46 fungal isolates represented by 9 fungal genera were isolated from the samples belonging to the three classes of fungi i.e. Zygomycetes, Ascomycetes and Basidiomycetes. The post-harvest mycoflora was represented by Rhizopus, Aspergillus, Alternaria, Fusarium, Chaetomium, Penicillium, Geotrichum, Ulocladium and Ustilago. The most predominant genera were Fusarium with nine isolates followed by Alternaria with eight isolates. The information on the diverse groups of post harvest mycoflora can help in effective management and minimization of post-harvest economic losses and the risk of a number of human, plant and animal diseases.
