| Abstract: | The effect of different Ca2+ concentration on cold-resistance of the detached leafs of citrus was studied.The result showed that the treatment of 10-20 mmol/L Ca2+ could increase the soluble sugar and protein content,enhance the activities of SOD and POD and reduce the MDA accumulation.The results indicated that Ca2+ would increase the cold resistance of citrus leaves. |
