通过对栗芽的观察研究,明确了栗树新梢上的叶、芽、花序均在芽内奠基;雄花序主要在芽形成的当年的6—8月分化;混合花序在冬季休眠后至萌芽前分化,混合花序是由冬前雏梢分化期分化的雏梢叶腋间的芽原基发育而成;混合花序的分化是芽已经在上年分化有雄花序的基础上进行的;不同的修剪方法对花芽的分化有不同的作用,休眠期对弱枝疏剪,有促进完全混合芽形成的作用;对外围延长枝的短截及完全混合芽的形成有不利的影响;栗的许多生长结果特性均受芽发育特性的影响。
Through the observation and study of the chestnut buds, it was clear that the leaves, buds and inflorescences of the chestnut shoots were all laid in the buds. The male inflorescences were mainly differentiated from June to August of the current year. The mixed inflorescences differed after dormancy in winter to budding , The mixed inflorescence is developed by bud primordia between axillary axons of young shoots differentiated in winter; the buds of mixed inflorescences are already budded on the basis of the male inflorescences differentiated in the previous year; different pruning methods Differentiation of flower buds had different effects. During dormancy, sparse shearing of weak branches promoted the formation of completely mixed shoots, and had an adverse effect on the formation of short stings and complete mixed buds of peripherally prolonged branches. Many of the growth characteristics of chestnut Affected by shoot developmental characteristics.
