| 摘 要： | 通过荔枝胚珠发育观察发现，胚珠发育特点同花蕾外部开矿及不同花类型密切相关，提出了荔 枝不同类型花歧化发育的假设模式：胚珠在孢子母细胞时败育，严重萎缩，导致雄花的形成；若胚珠在功能大孢子出现前后败育，则在胚珠形成椭圆的、内含皱折的空腔，决定雄能花的形成；若胚珠能通过２核胚囊期，则建成雌蕊结构完整的雌能花。

| Abstract: | The close relationship among the distinctions of ovule development,the types of litchi flower bud and flower types was observed.The hypothesis of different types of flower development is advanced:If the ovule aborts at the stage of megaspore mother call,the ovule will atrophy seriously and male flower will form.If the ovule aborts before or after the stage of functional megaspore,an elliptical sac with rugosity from in the nucellus,and functional male flower will from.Past the stage of two nucleus embryo sac,pistil will develop completely,and functional female flower will form. |
