忍冬全株花芽的分化发育

DIFFERENTIATION OF FLOWER BUDS OF A WHOLE HONEYSUCKLE PLANT

摘要: 用整体解剖法研究了忍冬Lonicera japonica Thunb.花芽的分化发育规律。结果表明,它是多级枝先后多次分化花芽的类型。在南京地区,从2月下旬到10月底分化Ⅵ级分枝;每级枝在山脓芽分化发育成分枝的前期时,都能分化一些节数的花芽;花芽分化的速度、数量和发育间隔期随当时温度而变化。从花芽分化到开花分5个时期。

Abstract: A gross anatomical study on the flower bud differentiation of a whole honeysuckle plant (Lonicera japonica Thunb.) was made throughout its growing period. The results showed that it was mutistage type of differentiation on different branches. The plant gr
