The aim is to evaluate the effects of foliar applications of proline, ascorbic acid, and salicylic acid on spinach exposed to varying salinity levels.
Plants were treated with proline, ascorbic acid, and salicylic acid at regular 14-day intervals.
Different salinity levels (0.38 to 15.0 dS m−1) were applied to the irrigation water.
Physiological parameters, including growth metrics and enzyme activities, were assessed.
15 dS m−1 salinity reduced leaf area by 53.23% and stomatal conductance by 83.07%.
Proline application improved yield by 9% and chlorophyll content by 8.5%, outperforming other treatments.
Antioxidant enzyme activities increased by 24.4–66.7% with proline treatment, enhancing plant resilience under stress.
