Abstract

Spider mite invasion induces oxidative stress on bean plants and increased soluble sugars, phenole, proline and peroxidase activity, but decreased catalase activity and ascorbic acid and carotenoid concentration. Application of elicitors significantly enhanced spider mite tolerance by decreasing hydrogen peroxide, malondialdehyde, electrolyte leakage, and increasing peroxidase activity and antioxidant compounds reported previously, leading to increasing ion percentage in plant shoot. This finding suggests that elicitors might be activating antioxygenic enzymes and elevating antioxidants there by controlling free radical generation, hence preventing membrane peroxidation and denaturation of biomolecules resulting into improving plant growth.Keywords: Tetranychus urticae, Phaseolus vulgaris, salicylate, methyl jasmonate, antioxidants.
