The present study scrutinized the influence of foliar application methyl jasmonate on physiochemical characteristics and antioxidant enzymes two grapevine rootstocks, ‘SO4’ (high drought tolerance) ‘101-14’ (low tolerance), under conditions. seedlings were sprayed with at 100 µM 3-day intervals throughout 28-day stress period. results showed that treating both rootstocks greatly minimized adverse effects reactive oxygen species caused by drought. Specifically, substantially reduced levels malondialdehyde, hydrogen peroxide, ion leakage while increasing photosynthetic pigment levels, soluble carbohydrates, proline, protein, total phenols content. Additionally, applying improved action like superoxide dismutase, ascorbate peroxidase, catalase. This made membranes leaves more solid during Methyl treatment oxidative damage mineral element (P, K, Mg, Ca, Fe, Zn) accumulation in green treated plants as opposed to drought-untreated plants. These noticeable compared rootstocks. Based these results, grapevines may be considered a novel strategy for mitigating water scarcity production system.
