巴旦杏花芽形态分化自 7月上中旬始到 9月底结束 ,小短果枝花芽分化时间早于其它各类果枝 ;同一时间 ,花芽分化率表现为小短果枝 >短果枝 >中果枝 >长果枝。短果枝不同部位花芽分化程度及分化率表现为上部 >中部 >下部。生长健壮的徒长枝和发育枝上也有花芽形成。不同枝上花芽的类型、分布、成花率、座果率均有较大差异 ,成花率以小短果枝和短果枝最高 ,为 83.6%和84 %。座果率以短果枝最高 ( 2 7.8% )。各类枝的不同枝势对其上花芽分化进程、分化率有极大影响
The albino flower bud morphological differentiation began from the middle of July to the end of September, and the differentiation of the small short fruit buds was earlier than that of other fruit branches. At the same time, the rate of flower bud differentiation was short short fruit branch> short fruit branch> middle fruit branch> long fruit branch. The differentiation degree and differentiation rate of flower buds in different parts of short fruit branches showed upper part> middle part> lower part. Growth of robust leggy branches and development of branches also have flower buds. Flower buds on different branches of the type, distribution, flowering rate, fruit set rates are quite different, flowering rate to the short short branches and short branches, the highest, 83.6% and 84%. The fruit rate was the highest with short fruit branches (2 7.8%). Different branches of various branches on its flower bud differentiation process, the differentiation rate has a tremendous impact
