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。 The whole body dissection method was used to study the differentiation and development of Lonicera japonica Thunb. flower buds. The results show that it is a type of multi-stage branch multiple times to differentiate flower buds. In the Nanjing area, from the end of February to the end of October, VI branching was differentiated; each branch in the early stage of the differentiation and development of branch pus buds can differentiate some flower buds; the speed, number and development interval of flower bud differentiation The period changes with the temperature at that time. From flower bud differentiation to flowering in 5 periods.
