Mitigation of Salinity Stress on Pomegranate (Punica granatum L. cv. Wonderful) Plant Using Salicylic Acid Foliar Spray

Salt stress significantly impacts plant morphological structure and physiological processes, resulting in decreased growth. Salicylic acid (SA) is a key signal molecule that protects plants from the negative of salinity. Under natural conditions, pomegranate generally exhibits salt-tolerant characteristics. The objective this study was to elucidate salt-tolerance level (Punica granatum L. cv. Wonderful) effect regulating strategy SA foliar spray on growth, structure, processes. levels were 0, 0.25, 0.50, 1 mM presence salinity 10, 35, 70 NaCl, respectively. Vegetative growth indices, including stem cross-sectional area, leaf total dry weight, lowered by treatments. However, applications greatly improved characteristics under salt stress. effects effectively reversed treatment at compared control other Interestingly, enhanced chlorophyll, phenolic, carbohydrate, proline contents leaves while decreasing electrolyte leakage (EL), Na, Cl levels. Moreover, treatments nutrient content increased activities peroxidase (POD) catalase (CAT), with decrease malondialdehyde (MDA) content. This suggests alleviation may be due activation antioxidant enzymatic mechanism lipid peroxidation plant.
