| 摘 要： | 日本矮紫薇花芽由中上部侧枝和主枝顶芽发育而成,花芽分化从4月末开始至5月末结束,历时30d,包括花序分化和小花分化两个过程,分为形态分化前、开始分化期、花序原基分化期、花蕾分化期、小花花萼分化期、花瓣分化期、雄蕊分化期、雌蕊分化期8个时期,花序和小花分化的顺序分别是离心和向心的.花芽分化与春梢生长有一定的相关性. |

| Abstract: | Flower bud of Lagerstroemia indica cv. turns from middle or topper bud of auxiliary shoot and terminal bud and the flower bud differentiation process lasted about 30d from late April to late May. The paraffin cut was used to observe the developing process of the flower bud differentiation. The results showed its differentiation includes two proces- ses of differentiation of inflorescence and of floret. The process can be divided into 8 phases, vegetative, initial, inflorescence primordium, single flower primodium, sepal, petal, stamen and pistil differentiation phase. The differentiation of inflorescence and single flower is outward and centripetal respectively. And there is some relative between the flower bud differentiation and the growth of shoots. |
