| Abstract: | The effect of Ca~(2+) on cold resistance of Trifolium was studied. The results showed that Ca~(2+) could retard the degradation of chlorophyll in Trifolium leaves under cold stress and increase the contents of soluble sugar, proline and vitamin C; Ca~(2+) could also maintain the stability of plasmalemma and decrease the accumulation of O~~ 2 and MDA; keep high activity of SOD and POD. |
| |
| Keywords: | Ca~(2+) Trifolium cold stress plasmalemma permeability |
