Contamination of agricultural soils with heavy metals (HMs) has posed major threat to the environment as well human health. The aim this study was appraise efficiency key-antioxidant enzymes in enhancing plants' tolerance HMs (heavy metals) like copper (Cu) and Cadmium (Cd), under action methyl jasmonate (Me-JA) Cajanus cajan L. Seeds C. treated Me-JA (0, 1 nM) were discretely subjected noxious concentrations Cu Cd 1, 5 mM) raised for 12 days controlled conditions plant growth chamber biochemical analysis. In contrast Cd, triggered oxidative stress more significantly (44.54% mM increase MDA compared control) prominently thereby affecting physiological attributes. By activating antioxidant machinery, pre-treatment reduced HMs-induced stress, increased proline production, glutathione (41.95% when nM treatment) ascorbic acid content by 160.4 % aforemtioned treatments thus improving redox status. Thus, light our results put forward a firm basis positive role that might play mitigation caused due stimulating defense system leading overall improvement seedlings.
