山桐子雌雄及两性花分化的形态学研究
A Study on Floral Organ Morphogenesis in Male,Female and Hermaphroditic Flowers of Idesia Polycarpa
[目的]对山桐子雌、雄及两性花发育过程进行外部形态和内部微观构造进行观察和分析,为丰富山桐子成花基础理论和人工调控山桐子的开花结实等提供依据。[方法]在山桐子雌、雄及两性花发育过程期间,观察并拍照记录雌、雄花芽和雌、雄以及两性花的花序和小花的外部形态变化;采用普通石蜡切片技术对雌、雄以及两性花的内部组织进行观察分析。[结果]1)山桐子 3 种不同性别的花在花器官发育初期都有雌蕊和雄蕊,三者发育初期都处于"两性花"时期,但是在"两性花"时期之后,雄…查看全部>>
[Objective]Combing with the observed inner microscopic structure and morphological characteristics of male,female and hermaphroditic flowers in Idesia Polycarpa,the different floral parts of them were analyzed,which provided theoretical basis for increases fruit number,and the mechanism of sex determination in I.Polycarpa.[Method]During the inflorescence and floret stage of the female,male and hermaphrodite flowers,the external morphology of these flowers we…查看全部>>
