Salinity has become a major environmental concern of agricultural lands, impairing crop production. The current study aimed to examine the role zinc oxide nanoparticles (ZnO NPs) in reducing oxidative stress induced by salinity and overall improvement phytochemical properties barley. A total nine different barley genotypes were first subjected salt (NaCl) hydroponic conditions determine tolerance among genotypes. genotype Annora was found as most sensitive, tolerant Awaran 02 under stress. In another study, sensitive (Annora) (Awaran 02) grown pots (100 mM). At same time, half provided with soil application ZnO NPs mg kg –1 ), other foliar sprayed L ). reduced growth both compared control plants. However, greater reduction (sensitive genotype) than (tolerant genotype). exogenous ameliorated improved biomass, photosynthesis, antioxidant enzyme activities damage caused this positive effect observed more genotype. Furthermore, effective NPs. Findings present revealed that could be promising approach alleviate levels tolerance.
