Protective effects of cerium oxide nanoparticles in grapevine (Vitis vinifera L.) cv. Flame Seedless under salt stress conditions

High levels of soil salinity can cause substantial decline in growth and productivity crops worldwide, thus representing a major threat to global agriculture. In recent years, engineered nanoparticles (NPs) have been deemed as promising alternative combating abiotic stress factors, such salinity. this context, the present study was designed explore potential cerium oxide (CeO2NPs) alleviating salt grapevine (Vitis vinifera L. cv. Flame Seedless) cuttings. Specifically, interaction between CeO2 NPs (25, 50 100 mg L−1) (25 75 mM NaCl) evaluated by assaying an array agronomic, physiological, analytical biochemical parameters. Treatments with NPs, general, alleviated adverse impacts (75 significantly improving relevant agronomic traits grapevine. ameliorated chlorophyll damage under high Furthermore, presence attenuated salinity-induced damages indicated lower proline, MDA EL; however, H2O2 content not stress. Additionally, caused increases enzymatic activities GP, APX SOD, compared control plants. Similar conditions, all concentrations triggered activity, while highest concentration increased GP activity. However, did modify SOD Considering mineral nutrient profile, Na Cl well Na/K ratio, it decreased K, P Ca contents. Nevertheless, lead significant alterations Na, K salt-stressed Taken together, current findings suggest that could be employed salt-stress agents
