Exogenous Application of Proline and Salicylic Acid can Mitigate the Injurious Impacts of Drought Stress on Barley Plants Associated with Physiological and Histological Characters

Barley is a very important crop worldwide and has good impact in preserving food security. The impacts of 10 mM proline and 0.5 mM salicylic acid were evaluated on water stressed barley plants (<i>Hordeum vulgare</i> L. Giza126). Salicylic acid and proline treatments led to increased ste...

Nevertheless, lipid peroxidation, electrolyte leakage (EL), superoxide (O<sub>2</sub><sup>·−</sup>), and hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) significantly decreased in treated barley plants with proline and salicylic acid in both growing seasons as compared with drought treatment only, which caused significant decrease in stem length, plant dry weights, chlorophyll concentration, activity of antioxidant enzymes, as well as biological and grain yield. These results demonstrated the importance of salicylic acid and proline as tolerance inducers of drought stress in barley plants.https://www.mdpi.com/2071-1050/12/5/1736barleydroughtenzymes activityelectrolyte leakagescanning electron microscope
