转Bt基因抗虫棉苗期生长性状及叶片解剖结构

Growth character and leaves anatomical texture of transgenic Bt pest-resistant cotton in period of seedling

结果表明,转Bt基因抗虫棉株形紧凑,叶片较小且厚,叶色浓绿,群体透光性好;叶片海绵组织的细胞形状、大小和排列方式都发生了明显变化。

The result shows that the shape of the insect-resistant cotton that a p roduct of Transgentic Bt are compact:the leaves are small and thick:the color is deep green: and the sunlight can easily get into the community.The shape, size and the way of arrangement of the cells on the sponge tissue of leaves all chang e a lot.
