Regulation of plant hormone on the layout of microtubule and cellulose microfibril;
植物激素对微管和纤维素微纤丝排向的调节
In this paper, the dynamic changes of lignin deposition and the connection between lignification progress and cellulose microfibrils (CMfs) structure in cell wall were analyzed on the basis of cytochemistry localization of lignin and CMfs with KMnO_4 staining, and lead citrate and uranyl acetate staining.
随着S1和S2层纤维素微纤丝(CMfs)的沉积,木质素开始沿初生壁角隅处,向胞间层其它区域和次生壁各层同时扩展,整个木质化过程并不是由胞间层依次向次生壁各层推进。

本文利用X射线衍射法和自编的软件对杉木的微纤丝角进行了测定,结果表明:微纤丝角受很强的遗传控制,在不同株间、幼龄材间及成熟材间的差异极不显著;微纤丝角受树木生长年龄的影响很大,近髓心处最高,自髓心向外迅速减小,9 a以后减小趋势缓慢,到大约15a时出现最小值,最大值与最小值相差达20多度,回归分析得到的二项式方程R2达到0。

现在人们已清楚地知道针叶材具缘纹孔的纹孔膜由塞缘和纹孔塞组成,悬挂纹孔塞的塞缘由连接到纹孔缘基部的微纤丝束形成,这些微纤丝束随意结合形成网状构造,因此纹孔膜小孔的大小、形状极不规则。
The two treatments make a big improvement on the measurement of the microfibrillar angles of softwood.
