摘要: 采用石蜡切片方法观察桂花四季桂品种群的‘天香台阁’(Osmanthus fragrans‘Tianxiang Taige’)花芽分化的过程。研究表明,‘天香台阁’具3种不同的花芽,即普通花芽、特殊花芽、叶状花的台阁花芽。普通花芽和特殊花芽形态分化相同,分为总苞分化期、花原基分化期、顶花花被分化期、雄蕊分化期及雌蕊分化期共5个时期,历时约5个月;而叶状花的台阁花芽除了这5个时期,最后还经历台阁形成期,共历时约6个月。3种花芽雌蕊均发育异常,台阁花芽中本应着生雌蕊的部位分化为枝条。

关键词: 桂花, 花芽, 形态分化

Abstract: The paraffin method was used to study the process of floral-bud differentiation in Osmanthus fragrans‘Tianxiang Taige’. The results show that three different types of flower buds,normal flower bud,special flower bud,and leaflike proliferate-flower bud,were founded in O. fragrans ‘Tianxiang Taige’. The normal and special flower buds shared a common 5-stage morphological differentiation process that was about 6 months. The stages inclued involucrum differentiation,flower primordium differentiation,top flower perianth differentiation,stamen differentiation and pistil differentiation. The pistils degenerated in all three different types of flower buds. The proliferate-flower bud produced atrophied pistils,which were replaced by meristems that eventually differentiated into leaves and branches.

Key words: Osmanthus fragrans, floral-bud, morphological differentiation
