摘要
Powdery mildew infection induced synthesis of beta-1,3 glucanase in both resistant and susceptible lines of pea. Increase was most conspicuous and drastic in resistant as compared to susceptible genotypes. Maximum beta-1,3 glucanase activity was recorded 6-8 days after spore inoculation. Enzyme activity triggered 10-15 days before visible symptoms were observed. At later stages of crop growth a drop in beta-1,3 glucanase activity was recorded which might be one of the possible reasons for reduction in resistance even in resistant genotypes during this period.
