| 摘 要： | 为了确定叶底红的花芽分化特性,采用改良的石蜡切片法对叶底红花芽分化过程进行形态学观察。结果表明,叶底红的花芽分化过程依次从外向内发育,可分为花序原基分化期、花原基分化期、花萼原基分化期、花瓣原基分化期、雄蕊原基分化期和雌蕊原基分化期。福建漳州地区叶底红的花期从2月份持续到8月份,每轮花芽分化的时间约为30d。

| Abstract: | To study the characteristics of the flower bud differentiation of Phyllagathis fordii, an improved paraffin dissection method was adapted for amorphologic observation.The result indicated that the differentiationsinitiated from the external of a bud, starting on inflorescence primordiumfollowed by flower primordium, sepal primordium, petal primordium, stamen primordium, and finally, pistil primordium.The annual flowering season of P.fordii in Zhangzhou area lasted from February to August.It took approximately 30 days to complete one differentiation cycle. |
