| 中文摘要: |
| 采用形态解剖和石蜡切片法，对雄蕊雌化辣椒花和果实发育过程进行观察。形态学观察结果表明，雌化
花芽较正常花芽肥大，雌化雄蕊可结实但非常小，位于正常辣椒果实果柄处。另外有部分雄蕊雌化和雄蕊全部雌化
两种突变体。显微切片结果显示，雌化雄蕊原基呈扁平叶状突起，后期发育成类似心皮的叶状体，边缘靠合或缝合形
成类似边缘胎座的子房。雄蕊在雌化过程中，形态上表现不同程度雌化，并且表现出一系列的中间过渡类型。另外雌
化“子房”内有“胚珠”,并且雌化雄蕊的“胚珠”与正常子房中的胚珠相似。 |
| 英文摘要: |
| The development process of flower and fruit of feminization stamens of Capsicum annuum L. were
conducted by the morphological and anatomical method and common plant paraffin section method. The morphological
observation showed that, feminization bud was bigger than normal bud. Feminization stamens could fruit but the fruits were
very small, and the small fruits were located at normal peduncle of pepper. It also found two mutants of some stamens
feminization and all stamens feminization. According to the results of microscopic section, we knew that feminization
stamen primordium presented leafy protrusions as flat, later developed into similar carpel thallus, forming the marginal
placentation by edges conniventting or stitching together. In the process of feminization, stamens showed different levels of
feminization, and showed a series of intermediate transition types. The other feminisation ovary冶with ovule and
feminization stamens of the ovule were similar to those of normal ovary of the ovule. |
