摘要: 为比较桃和李不同品种花芽生理特性与萌发率的关系,选取休眠期4个桃树品种和3个李树品种为试材,测定了花芽萌发率和与休眠期相关的含水量、可溶性糖含量、可溶性蛋白含量等生理指标。结果表明:李品种中,‘秋姬李’的各项指标含量均为最高,‘苦李’萌芽率、可溶性糖和含水量含量最低,可溶性蛋白显著低于‘秋姬李’;桃品种中,‘早黄金’萌发率最高,可溶性蛋白显著高于其他品种,‘黄金香2号’可溶性糖含量最高。各项休眠相关的生理指标隶属函数平均值为:李中,‘秋姬李’(1.000)>‘红李优系’(0.239)>‘苦李’(0.213),桃中,‘早黄金’(1.000)>‘伏里红’(0.598)>‘巨黄油’(0.270)>‘黄金香2号’(0.157),3项指标综合分析后发现其结果与萌发率指标存在较好的一致性。

Abstract: In order to compare the relationship between physiological characteristics and germination rate in flower bud of different varieties, four peach varietiesin dormant period and three plum varieties were selected, and flower bud germination rate, the period related water content, soluble sugar content, soluble protein content and other physiological indicators indicators were determined. The results showed that all indexes of Qiu Jili were the highest. The bud rate, soluble sugar and water content of Kuli were the lowest, and the soluble protein was significantly lower than Qiu Jili. Among peach varieties, Zao Huangjin germination rate was the highest, and soluble protein was significantly higher than other varieties. Soluble sugar content of Huang Jinxiang NO.2 was the highest. Mean values of membership were as follows: Qiu Jili(1.000)>Raspberry Optimal(0.239)>Kuli(0.213); Zao Huangjin(1.000)>Fu Lihong(0.598)>Ju Huangyou(0.270)>Huang Jinxiang NO.2(0.157). After comprehensive analysis of the three indexes, it was found that there was a good consistency between the physiology characteristics and the germination rate indexes.
