| 摘 要： | 以花椰菜细胞质雄性不育系09-R9为试材，以可育材料24为对照，采用常规石蜡切片技术，对花椰菜细胞质雄性不育系的花药败育过程进行细胞学研究。结果表明：花椰菜细胞质雄性不育系的花药可以形成部分外形正常的花粉囊，但囊内物质随着花蕾的发育逐渐解体，最终这种不正常的花粉囊全部解体消失。不育系花药发育受阻于花粉母细胞形成之前，此时花粉囊内未见绒毡层，可能是其本身并未形成绒毡层。

| Abstract: | In this paper,taking cytoplasmic male sterility line 09-R9 as experimental material and fertile material 24 as the control,anther abortion processes of cytoplasmic male sterility in cauliflowers Brassica oleracea L.var.botrytis L.was studied by paraffin section.The result showed that the anther of cytoplasmic male sterility could partially form normal pollen sac,before microspore mother cell stage,the pollen development had been interrupted.Finally,the normal pollen sac were disappeared.In microspore mother... |
