摘　　要：With a kernel apricot cultivar Youzhu 07-3 as the test material, the effects of exogenous calcium and calcium inhibitor on the cold resistance of pistils were investigated. In the bud germination and enlargement period, exogenous calcium and calcium ion inhibitor were sprayed to the kernel apdcot trees, respectively. At the full-bloom stage, a certain number of flower branches of kernel apricot were sam- pied and subjected to low-temperature stress indoor, and the soluble sugar content, MDA content, SOD activity and POD activity in the pistils were determined. The results showed that exogenous calcium increased the soluble sugar content, reduced the MDA content and improved the SOD and POD activity in pistils, and it significantly relieved the cold damage to pistils and improved the cold resistance of pistils; while exogenous calcium ion inhibitor showed the opposite effects.用杏扁优株‘07-3’作为研究材料。在花芽萌动期和膨大期进行树体喷钙和喷钙离子抑制剂处理,采集盛花期花枝进行室内模拟低温试验,调查低温下不同处理杏扁雌蕊冻害,通过测定不同处理雌蕊的可溶性糖含量、MDA含量、SOD活性和POD活性,研究外源钙与杏扁雌蕊抗寒性间的关系。结果表明,外源钙处理提高了雌蕊可溶性糖含量,降低了雌蕊MDA含量,增强了雌蕊SOD酶活性和POD酶活性,显著降低了雌蕊的冻害,提高了其抗寒能力;外源喷钙离子抑制剂处理则相反。
