| Abstract: | Objective ] The aim was to study the effect of different concentration cadmium on the roots activity and grain quality of rice in cold area. Method] Pot experiment method was adopted to study roots activity of rice in various growth stages and content of cadmium, together with the quality of rice. Result] With the increase of Cd concentration, the roots activity of different growth period and the content of protein was decreased significant, but increased the Cd concentration of plant. Conclusion] The roots activity of rice and the content of protein was decreased under Cd contamination. |
