摘要 用扫描电镜对夏棉中16胚珠纤维细胞进行观察,结果显示胚珠上纤维细胞的启动分化和发育在时间和部位上有一定顺序。胚珠表皮细胞启动分化为球形突起状的纤维细胞需要2~4h,胚珠上各部位纤维的发生顺序是:先从中部开始后向两端扩展,向胚珠合点扩展较快,向珠孔端扩展较慢,近珠孔瑞纤维发生最晚。 It shows that the start,Cifferentiation and development of ovule fibre cell are diffferent in time and order by observing that of Summer 'Zhongmian' Cotton Seed No. 16 through the scanning electron-microscope. It takes the ovule cell 2 to 4 hours to be in globular shape.The order of producing fibre on the ovule is that it begins in the centre and spreads in two ends,more quickly in the joint of ovule but slowly in the ends,latest nearby the ends.
