Abstract:
Plants use a variety of physio-chemical mechanisms to defend themselves from biotic stresses induced by insect pests. An investigation was undertaken to evaluate the response of oxidative enzymes, viz., catalase, peroxidase and polyphenol oxidase in okra germplasm for resistance/susceptibility to leafhopper, Amrasca biguttula biguttula (Ishida) at All India Coordinated Research Project on Vegetable Crops, Odisha University of Agriculture and Technology and Central Horticultural Experiment Station, Bhubaneswar during kharif, 2018, summer, 2019 and kharif, 2019. Oxidative enzyme activity was estimated spectrophotometrically from leaf samples collected at peak jassid infestation period (49 – 63 days after sowing). The results indicated that the resistance germplasm BBSR-37, Pusa A-4, BBSR-36, BBSR- 57, BBSR-47 and BBSR-3 recorded higher enzymatic activities as compared to susceptible germplasm (Pusa Sawani and BBSR-53). The germplasm BBSR-4 and BBSR-09-6 were observed with moderate level of enzymatic activity. The results revealed that the enhanced activities of the enzymes may contribute to bio-protection of okra genotypes against leafhopper infestation.
