摘要: 金边瑞香花芽由顶芽发育而成,花芽分化包括花序分化和小花分化两个过程,分为未分化、
开始分化、花序原基分化、小花原基分化、花瓣分化、雄蕊分化和雌蕊分化7个时期,分化的顺序是向心的;分化的临界期为5月中旬,分化时期长达7个月,花芽分化既持续又表现出两个分化高峰,还受温度等因素的影响。

Abstract: Flower bud of Daphne odora var. narginata Mak. turns from terminal bud. Its diferentiation includes two processes of diferentiation of inflorescence and of floret, can be divided into seven developmental stages:undiferentiation, different beginning, differentiation of inflorescence, floret, petal, stamen and pistil. The flower bud differentiation begins on May middle and requires 6—7 months. Flower bud differentiation is individual and may be dirided two rapid times. The bud diferentiafton is affected by temperature et al.

Key words: Daphne odora var. narginata Mak., Flower bud diffierentiation
