The morphological plasticity of plant roots is a key factor in their ability to tolerate wide range edaphic stresses. There are many unanswered questions relating nanotechnology and its potential uses for sustainable agriculture. main purpose this study was examine the effects salinity-induced morphogenic responses zinc oxide nanoparticles (ZnO-NPs) on root characteristics, growth, MDA content, antioxidant enzymatic activity, ion accumulation rice (Oryza sativa L.). experiment conducted hydroponic culture containing 50 mg/L ZnO-NPs different concentrations (60, 80, 100 mM) NaCl 14 days. results indicated decrease growth due exposure salinity (length, fresh, dry weight). showed that caused reduction Higher sodium (Na+) accumulation, potassium level decreased with increasing salinity. Root length, fresh weight, K+ activity were all enhanced by applying often SEM analysis revealed treatments significantly improved morphology. notable Na+ content as result, which K+/Na+ ratio rice’s system. These findings suggest O. sativa, when treated ZnO-NPs, can thrive under salt-stress conditions, opening up possibility cultivating extreme climates.
