Induction of defence related biochemical responses by different treatments (elicitors, bioagents, antibiotics and chemicals) in citrus against Xanthomonas axonopodis pv. citri

Abstract

The glasshouse and laboratory experiments were conducted to evaluate the enzymatic activity of the antioxident enzymes viz; Phenylalanine ammonia lyase (PAL), Catalase (CAT) and Peroxidase (PO) against X. axonopodis pv. citri for different treatments at, Department of Plant Pathology, College of Agriculture, G.B.P.U.A. &T., Pantnagar. Experiment was laid out in Completely Randomized Design (CRD) in glass house comprising ten treatment combinations replicated thrice, where the pretreatment of citrus plants with Pant bioagent 2, Pant bioagent 3, L-methionine, GABA and Salicylic acid induced the levels of plant defense and thus induced disease resistance against X. axonopodispv.citri. These compounds can be used as effective alternative compounds to copper bactericides for the management of citrus canker.
