Abstract


Production of pectic enzymes by Corynespora cassiicola (Berk. and Curt.) wei. causing leaf spot disease on blackgram was studied both in vitro and in vivo. The principal enzymes involved in disease production are Pectin methyl esterase (PME), Pectin Methyl Transeliminase (PMT), Polygalacturonase (PG). The activity of PG was more in vivo (35.31%) than in vitro (17.86%) where as the activity of PME & PMT were more in vitro than in vivo. None of the enzymes could detected in healthy tissue.
