| 摘 要： | 为探讨不同苹果砧木的抗寒性,在低温处理条件下,比较分析了12种苹果砧木的抗寒生理指标的变化规律。结果表明:12份参试材料中山丁子的蛋白质含量、可溶性淀粉含量以及SOD活性最高;MD001的可溶性糖含量和CAT活性最高,GM310的POD活性最高,表明山丁子、MD001和GM310的抗寒性较强。进一步方差分析表明,不同砧木叶片间SOD活性、POD活性、CAT活性、可溶性糖含量以及可溶性蛋白质含量差异均达到极显著水平(P0.01),即不同砧木的抗寒性存在极显著差异。

| Abstract: | To explore the cold resistance of different apple stocks,the physiological changes for 12 varieties of apple stocks at low temperature were analyzed comparatively. The results showed that the protein content,soluble starch content and SOD activity were the highest in Shandingzi,and the soluble sugar content and CAT activity of MD001 were the highest, GM310 had the highest POD activity, which indicated that Shandingzi, MD001 and GM310 had stronger cold resistance than the others among the 12 apple stocks. Further variance analysis showed that there were extremely significant differences of the SOD activity,POD activity,CAT activity, soluble sugar content and soluble protein content between 12 stocks（P〈0.01）,which indicated that different cold resistance was among different stocks. |
