Induction of defense enzymes in groundnut upon treatment with bioagents and botanicals

Abstract:
Groundnut is one of the most consumed food legumes of the world. Foliar diseases such as late leaf spot (Phaeoisariopsis personata Berk. and Curt.), early leaf spot (Cercospora arachidicola Hori.) and rust (Puccinia arachidis Spg.), poses major constraints in its production and productivity. Biological control offer better management opportunities than classical chemical control. Under present study, induction of defence enzymes (PAL (phenylalanine ammonia lyase), PO (peroxidase) and SOD (superoxide dismutase)) in groundnut treated with bioagents, botanicals and challenged with the foliar pathogens was studied. Highest PAL (3.161 U/mg protein) and POX (0.223 U/mg protein) activity was recorded in plants treated with sequential application of bioagents whereas, highest SOD activity was recorded in plants treated with P. fluorescens (9.492 U/mg protein). Untreated control has shown minimum defense enzyme activity. Results suggest the role of biocontrol agents in inducing higher defense enzyme activity.
