摘要: 应用石蜡切片技术对大田生长的天然有色棉(陆地棉)纤维的早期分化发育进行了研究。有色棉胚珠表皮细胞分化、突起时与普通白色棉一样,具有明显的形态学变化。但是,有色棉纤维突起的时间较白色棉迟,早期纤维细胞的伸长相对较慢,开花当天及开花后一天有色棉F/E值显著低于白色棉。

关键词: 有色棉, 纤维分化

Abstract: The study is conducted by applying paraffin. The results show that there are some distinct morphological changes in the differentiation of ovule epidermal cells in nature-colored cotton. But the differentiation time of ovule epidermal cells and early elongation of fiber cells and the F/E value of flowering day or the next day in nature-colored cotton are slower or lower than the control(Chuan 56).

Key words: nature-colored cotton, fiber differentiation
