Abstract
Aim: To evaluate the role of exogenously applied Methyl jasmonate (MeJA) and zinc concentrations on up-regulation of antioxidant defense machinery in salt-stressed chickpea plants. Methodology: A poly-house experiment framework of a Completely Randomized Design with three replicates by seed hardening in chickpea genotype BG-362 with 10 and 15 μM MeJA of combined with Zn under induced salinity stress. Results: Salinity induced membrane degradation in chickpea plants whereas seed hardening through MeJA (10 μM and 15 μM) in combination with micronutrient (Zn @ 15 mg kg-1 soil) reversed the pattern of membrane degradation in salinity stressed plants. Exogenously applied MeJA with Zn under induced salinity stress significantly up-regulated the antioxidant defense enzymes with noticeable values. Interpretation: Seed-hardening of MeJA and basal application of Zn is useful in alleviating the adverse effects of salinity stress in chickpea genotype BG-362 in salinity affected areas of U.P.
