苎麻纤维细胞壁具有6个层次,其中初生壁1层,次生壁5层。结合光学显微镜观察,发现苎麻纤维次生壁具3个不同的螺旋层次,即外层、中层和内层,内、外层纤维素微纤丝近横向排列,中层微纤丝近轴向排列;结节处纤维素微纤丝出现断裂、缺损或附加,这些是影响苎麻纤维长度、强力、光泽等品质的主要原因之一。

Ultrastructure of ramie was observed through transmission electron microscope to increase the yield and promote the quality of ramie and seek a way of scientific management of ramie. The results showed that fibre cell wall of ramie had 6 layers,1 of which formed the primary wall and 5 of which formed the secondary wall. By using optical microscope,it was observed that there were 3 different cellulose microfibil convoluting layers in the secondary wall,i.e. sexine layer,middle layer and internal layer. Cellulose microfibils appeared crosswise in the sexine and internal layer,axial arrangement i...
