Abstract
Under enhanced ultraviolet-B radiation(UV-B:280-320 nm),effects of calcium on biolo-gical characteristics of soybean seedlings were investigated. The results showed that calcium alleviated the inhibition of soybean seedlings on growth under UV-B stress. The decreasing degree of leaves weight for soybean seedlings treated with 15 mmol·L-1 calcium concentration was significantly lower than that of 5 and 0 mmol·L-1 calcium concentration. The height of the seedlings treated with 15 mmol·L-1 calcium was promoted under UV-B stress. The decreasing degrees of POD activity for soybean seedlings treated with 15 mmol·L-1 calcium concentration was significantly lower,whereas the increasing degrees of soluble protein content and SOD activity were higher. The experiment proved that calcium could mitigate the damage of ultraviolet-B radiation on soybean seedlings,and this effect was related to that calcium affected physiological and biological characteristics of soybean seedlings.
