Abstract: A laboratory experiment was conducted to assess the induced resistance in brinjal (CO-2) with the exogenous application of cis-Jasmone (CJ) and Salicylic acid (SA). Accumulation of antioxidant enzymes such as Peroxidase (POD), Polyphenol oxidase (PPO), Super oxide dismutase (SOD) and Catalase (CAT) upon infestation by brinjal shoot and fruit borer, Leucinodes orbonalis was taken as measure of induced resistance in the plants. Eight treatments were set up with two replications in each and one brinjal plant of 60 day old is tested. cis-Jasmone and Salicylic acid of 1mM concentration were used in the treatments. The activity of the antioxidant enzymes were recorded at 4, 24, 48, and 72 hours after the infestation. The induction of enzyme activities varied among the treatments and across the time interval. The treatment with infestation followed by CJ application showed greater level of enzyme activity from rest of the treatments and the second of such treatment was pre treatment with CJ followed by infestation. Thus, the result suggest that CJ induces greater level of resistance components in the plants against borer insect such as L. orbonalis and hence provide greater opportunity for exploiting plant defense against herbivores.
