Studies on seed-borne pathogens of some nigerian melons


N V Chiejina

Abstract



Fungi associated with three cultivars of melon seeds were investigated. The mycoflora were found to be more on the unshelled than on the shelled seeds of all the three cultirars tested. A total of nine fungal genera were isolated and identified while two were unidentified. C. vulgaris was infected with all the nine genera including the two unidentified genera. Percentage incidence of infection was observed to be higher for the unshelled than with the shelled seeds for all the cultivars. The genus, Aspergillus was the most predominant, with A. niger topping the list followed by R. stolonifer and the least was A. flavus. In view of the harmful effects of aflatoxin production by Aspergillus spp caution must be exercised in the consumption of stored ‘egusi' until an adequate control measure is in place.
