Causal fungi of post-harvest diseases of fruits and vegetables

記事区分：原著Post-harvest diseases of domestic and imported fruits and vegetables were surveyed once a week at Kyoto municipal central market and at small stores in Osaka and Kobe cities from May to November, 1990. Preliminary identification was done by the naked eye and with help of magnifier. After isolation of fungi on potato-dextrose agar medium, the spores formed by the isolates were compared with illustrations and descriptions in books on classification. Of the 63 isolates most had already been found on citrus fruit, stone fruits, pome fruits, berries, root vegetables, and fruit vegetables by other researchers. New findings were of Geotrichum sp. on Japanese apricot, Pestalotia sp. on plum, Aspergillus niger on apple, Manilla fructigena on Chinese quince, Trichothecium roseum on grape, Geotrichum candidum on carrot, Penicillium sp. on Chinese yam, Alternaria alternata on Japanese pepper, Alt. alternate, Fusarium sp., and Pen. sp. on malabar spinach, Pen. spp. on spinach, Alt. alternata, Cladosporium sp., Pen. italicum, and Pen. digitatum on maize, and Alt. sp. and Fus. sp. on globe artichoke. Fruit and leaf vegetables often had Pen. spp. (12 isolates), Fus. spp. (12 isolates) and Alt. spp. (11 isolates), but Mon. spp., Rhizopus spp. and Asp. spp. were recognized on fruits only, and Cladosp. spp. and Geot. spp. were found on both fruit and root vegetables. Some isolates of the former 3 genera have not yet been identified to the level of species. These fungi are important organisms in the study of post-harvest diseases, because the most likely produce mycotoxin that cause serious problems in animal and human health
