Hydroponically studies were conducted in rice seedlings (Oryza sativa L., cv. Tarom Hashemi) under different Zn levels. The nutrient solution treatments were prepared of three 4 zinc levels (0.5, 5,50 and 100 µM ZnSO4). Zn decreased Zn-TF, increased Zn accumulation in roots. Addition of Zn from 0.5 to 5 µM in nutrient solution increased shoot length, plant dry weight, superoxide dismutase (SOD) and decreased ascorbate peroxidase (APX) and guaiacol peroxidase (GPX) while addition of Zn from 5 to 100 µM had the reverse effects. https://biomedpharmajournal.org/vol5no2/effect-of-zinc-zn-on-some-physiological-characteristics-of-rice-seedling/ Zinc Accumulation Growth Oryza sativa Antioxidant enzymes
