Protease Activity By Common And Dominant Seed - Borne Fungi Of Green Gram.

Abstract

Green gram, Black gram, Pigeon pea and chickpea are common pulses in diet rich in carbohydrates, proteins and minerals. Numerous fungi affect pulses adversely causing reduction in seed content and seed health. During present study, effects of enzyme metabolites of common and dominant seed-borne fungi of test pulses on seed health of Green gram are evaluated. Total seventeen fungi recorded from all four test pulses. Out of these seventeen seed-borne fungi, six, Aspergillus flavus, A. fumigatus, A. niger, Drechslera tetramera and Rhizopus stolonifer, found to be common and dominant on all four test pulses. These common and dominant seed-borne fungi produced protease enzyme in variable quantity, which helped the fungi degrade the seeds and ultimately affected seed quality and yield.
