Drought stress affects the growth and quality of tea leaves. In this study, the effect of foliar spraying of different concentrations of methyl jasmonate (0, 0.1, and 0.2 mM) combined with salicylic acid (0, 0.1, and 0.2 mM) on increasing plant resistance to drought stress was investigated at the Iranian Tea Research Institute. Effect of drought stress in randomized blocks with 3 replications and three levels: 1- Complete irrigation 2- Irrigation interruption for 6 days with foliar spraying at two-day intervals for treatments T1 (0mj and 0SA), T2 (0.1 mM mj and 0 SA), T3 (0.2 mM mj and 0 SA), T4 (0 mj and 0.1mMSA), T5 (0.1mM mj and 0.1mMSA), T6 (0.2 Mm mj and 0.1 mMSA), T7 (0 mj and 0.2 mMSA), T8 (0.1mM mj and 0.2 mMSA), T9 (0.2Mm mj and 0.2mMSA) 3- Irrigation interruption for 12 days with foliar spraying for treatments. As a result of foliar spraying, an increase in catalase and SOD enzymes, total sugar and protein content, total carotenoid and chlorophyll, proline content, proline-5-carboxylate synthetase gene expression and catalase gene (CAT) were observed, which were significant at the P
