| Abstract | ||
| Water scarcity is a significant environmental stressor that adversely affects plant development. This research examines the beneficial role of ZnO/CuO nano-composites in alleviating the adverse impacts of water scarcity on improving pea plants. The foliar spraying of ZnO/CuO nano-composite solutions (25 and 50 ppm) enhanced the growth parameters of pea plants cultivated under both optimal circumstances (100% available water) and water stress circumstances (80 and 60% water available). Plants subjected to ZnO/CuO nano-composites (50 ppm) exhibited elevated concentrations of significant osmolytes, including proline, phenol, flavonoid, and tocopherol. They preserved their photosynthetic pigments more effectively than others applied under both stress and non-stress circumstances. Moreover, the external foliar spray of ZnO/CuO nano-composites decreased the levels of OH, H2O2, O2, and lipid peroxidation in pea plants exposed to water deficiency. The treatments enhanced the results, illustrating the advantageous effects of ZnO/CuO nano-composites, at a concentration of 50 ppm in mitigating the detrimental effects of soil water deficiency stress in pea plants. | ||
