Ca^(2+)对冷胁迫柑橘离体叶片的相关生理生化指标的影响

Effect of Ca^(2+) on the Correlative Physiological and Biochemical Index of Citrus Detached Leafs under Cold Stress

研究了不同浓度的外源C a2+对柑橘离体叶片抗寒性的影响。结果表明:10~20 mm o l/L C a2+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(M DA)的积累,从而提高柑橘的抗寒性。

The effect of different Ca^2＋ concentration on cold-resistance of the detached leafs of citrus was studied. The result showed that the treatment of 10-20 mmol/L Ca^2＋ could increase the soluble sugar and protein content, enhance the activities of SOD and POD and reduce the MDA accumulation. The results indicated that Ca^2＋ would increase the cold resistance of citrus leaves.
