摘要: 研究了不同浓度的外源Ca2+对柑橘离体叶片抗寒性的影响。结果表明:10~20 mmol/L Ca2+处理能够增加柑橘可溶性糖和可溶性蛋白质的含量,提高SOD和POD的活性,同时减少膜质过氧化物丙二醛(MDA)的积累,从而提高柑橘的抗寒性。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.
