摘要: 为比较苹果和梨不同品种休眠芽的生理变化与萌芽率的关系,以‘世界1号'‘晨阳'苹果和‘津香蜜'‘秋月'‘新梨7号'梨在冬季1—2月份的休眠芽为试材,分别测定了其萌芽率、可溶性糖含量、可溶性蛋白质含量、含水量。结果表明:苹果品种中含水量、可溶性糖含量、可溶性蛋白含量与萌芽率均为‘世界1号'>‘晨阳',其中芽的含水量与萌芽率极显著相关。梨品种中含水量、可溶性糖含量与可溶性蛋白含量差异显著,平均隶属函数值最高的为‘津香蜜',其次是‘秋月',‘新梨7号'最低。但梨的各项生理指标与萌芽率不相关。

Abstract: In order to compare the relationship between physiological changes and germination rate in dormant buds of different varieties of apple and pear, their germination rate, content of soluble sugar, soluble protein and water were measured with the apple buds of ‘Shi Jie 1' ‘Chen Yang' and pear buds of ‘Jin Xiangmi' ‘Qiu Yue' and ‘Xin Li 7' from January to February in winter. The results showed that apple of ‘Shi Jie 1' was always higher than ‘Chen Yang' in the content of water, soluble sugar, soluble protein and germination rate, and the content of water in buds was significantly correlated with germination rate. There were significant differences in content of water, soluble sugar and soluble protein among the pear varieties. ‘Jin Xiangmi' was the highest according to the average membership function value, followed by ‘Qiu Yue', with ‘Xin Li 7' the lowest. However, the physiological indexes of pear were not related to germination rate.
