Abstract

Accumulation of zinc in seeds of winter wheat plants grown at four different levels of zinc (Zn) in soil ranging from 0 to 810 kg/ha of added Zn and remobilization of Zn from seeds to seedlings leaves were examined. Lipid peroxidation, soluble protein content and activity of enzymes of antioxidant defense were also studied in seedling leaves. The accumulation of Zn in seeds and its remobilization from seeds into primary leaves was proportional to Zn supply. Inducible effect of Zn was found on activity of most enzymes of antioxidative defense (superoxid dismutase, catalase and peroxidase). Activity of glutathione peroxidase was decreased. Although Zn is essential micronutrient for plants and could act as an antioxidant at lower doses, at high applied concentrations act as a prooxidant evoking oxidative stress.
