Foliar Application of Zinc Oxide Nanoparticles to Mitigate Drought -Induced Oxidation Stress in Wheat

Background: Global agricultural production is seriously threatened by water scarcity and drought-induced oxidative stress, especially for crops that are sensitive to water, like wheat. Materials and Methods: The goal of this study is to determine whether applying zinc oxide nanoparticles (ZnO-NPs) that have been green-synthesized topically can help wheat suffer less from oxidative stress brought on by drought. The study focuses on wheat's physiological and biochemical characteristics under varied water conditions, including as growth, antioxidant defense mechanisms, and oxidative damage. Results: In the investigation, ZnO-NPs were employed at four distinct concentrations. The results emphasis the potential of ZnO-NP foliar sprays for enhancing wheat's resistance to drought stress by showing their beneficial impacts on wheat growth, chlorophyll content, increased shoot, root weight and antioxidant enzyme activities. Conclusion: This creative strategy conserves resources in areas with limited water supplies while increasing agricultural yield in an eco-friendly manner.
