| 摘 要： | 为研究苎麻雄性不育的早期表现和细胞学特征,采用常规石蜡切片,在显微镜下观察苎麻雄性不育系GS14-1及保持系GS13-X1的雄蕊发育过程.发现保持系GS13-X1的花药发育正常,形成正常的花粉粒;不育系GS14-1的雄性败育发生在较早阶段,多在雄花被形成后雌雄蕊原基分化期或花药形成初期发生败育,表现为雄蕊原基畸形或退化.但其败育的真正原因尚不清楚,有待进一步研究.

| Abstract: | To study male sterility(MS) and cytological features of ramie(Boehmeria nivea(L.) Gaud.),we observed process of stamen development in ramie MS line GS14-1 and its maintainer line GS13-X1,using Leica microscope to observe conventional paraffin section in this experiment.The results showed that the maintainer line GS13-X1 developed normally and produced normal microspores and pollen grains.The MS line GS14-1 presented in an earlier stage,mostly occurred in the period of primordial differentiation of stamen an... |
