苎麻雄性不育系与保持系花药发育的比较观察

Development of anthers in a male sterile line of ramie(Beohmeria nivea(L.)Gaud.)and its maintainer line

    摘要
  • 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 and pistil,and the abortion showed primordia of stamen was abnormal or degenerative.We should further study the real cause of abortion in MS line GS14-1 next work.
