观察了仁果类和核果类花芽鳞片的颜色差别、数目多少以及花芽分化的生物学进程,结果发现两类果树的花芽发育在营养生长的下半期就已经开始,在花芽分化之前或刚开始分化时,花芽分化趋势极不稳定;各品种花芽分化的时间很不一致,主要取决于树种和品种的固有特性以及外界因子的影响。 The color difference and the number of flower bud scales between pome and drupe were observed. The biological processes of flower bud differentiation were observed. The results showed that flower bud development of the two types of fruit trees began in the second half of vegetative growth. Before or at the beginning of flower bud differentiation , Flower bud differentiation trend is extremely unstable; flower bud differentiation time is very different, mainly depends on the inherent characteristics of species and varieties and the impact of external factors.
