Evaluation of Salicylic Acid Effects on Growth, Biochemical, Yield, and Anatomical Characteristics of Eggplant (Solanum melongena L.) Plants under Salt Stress Conditions

Salt stress is a major issue in agriculture and crop production that influences global food security. Mitigation options to address salt through agronomic practices can help manage this issue. Experiments were performed two summer seasons an experimental farm test the impact of three salinity levels (S): 300 (control), 1000, 2000, 3000 ppm, salicylic acid (SA) levels, including 1.0 1.50 mM, their interaction on growth yield eggplant (Solanum melongena L.) hybrid Suma. The results showed increasing S up ppm reduced plant fruit physical characteristics, as well leaf chemical especially total chlorophyll, carotenoids, relative water, nitrogen, phosphorus, potassium contents, which led reduction per plant. However, insignificant effect was observed control level 1000 saline water area, length, chlorophyll content, phosphorus In contrast, sugars, proline electrolyte leakage, TSS (total soluble solids), ascorbic contents improved with concentration compared control. tested parameters significantly higher due SA foliar spray mM besides photosynthetic pigments leaves enhanced by using mM. Using alleviated adverse plants until reflecting increase yield. anatomical structure revealed positive variations mature blades both stressed SA-treated plants. Based these results, use at may lessen negative impacts eggplant, increases overall
