Abstract
This study aimed to explore the mechanism by which Zn retards Fe toxicity by analyzing the morphological, photosynthetic, and chloroplast physiological parameters of wheat seedlings treated with either single or combined Zn and Fe. Different behavior of the seedlings was observed under untreated and treated conditions. The most discriminating quantitative traits were associated with leaf area, biomass dry mass and fresh mass, net photosynthetic rate, intercellular CO2 concentration, stomatal conductance, transpiration rate of seedlings, Hill reaction, Mg2+-ATPase and Ca2+-ATPase activities, malondialdehyde and O2·- contents, and glutathione reductase, ascorbate peroxidase, peroxidase, and superoxide dismutase activities and their gene expression in the seedling chloroplast. The obtained findings suggest the important function of an appropriate Zn concentration in preventing Fe toxicity. Therefore, a thorough evaluation of the effects of Zn on Fe-stressed plant growth is beneficial for sustainable agriculture.
