Effects of Selenium Ions on the Growth of Rice Seedlings

Abstract

For investigating the effect of selenium on the growth of rice seedlings, this study used different concentrations of selenium ions (0, 0.5, 5, 10 and 20 µmol/L) to treat rice seedlings hydroponically. The experimental findings demonstrated that rice seedlings could grow and develop properly in the presence of a selenium deficiency (0 mol/L). Selenium ions had a positive impact on the development of rice seedlings at low and middle selenium concentrations of 0.5 mol/L and 5 mol/L, boosting plant height, above-ground fresh and dry weights. Selenium ions had a substantial inhibitory impact on the development of rice seedlings at high selenium concentrations of 10 mol/L and 20 mol/L.
