Role of enzymes in resistance against fruit rot of chilli caused by Colletotrichum capsici (Syd.) Butler and Bisby

Type: article
Abstract: The activity of three enzymes namely peroxidase, poly phenol oxidase and catalase was observed in uninoculated and inoculated chilli fruits with Colletotrichum capsaici and it is observed that activity of all the three enzymes were increased at higher rates in response to inoculation of C. capsici and it was found that activity was less in susceptible genotypes than that of resistant genotypes. The peroxidase activity in resistant genotypes of uninoculated fruits ranged between 0.16 (Tiwan-13) to 0.26 (DCA-129) activity/min/g with mean of 0.21 activity/min/g. The peroxidase activity in resistant genotypes ranged between 0.16 to 0.26 activity/min/g whereas in susceptible genotypes it was ranges from 0.18 to 0.30 activity/min/g. The catalase activity in resistant genotypes of uninoculated fruits and ranged from 0.19 (DCA-193-1) to 0.31 (DCA-123,170-2) activity/min/g with mean of 0.25 activity/min/g.
