对海岛棉40个品种(系)的纤维水溶性总糖量、水溶性糖组分、微观结构参数和纤维比强度的分析测试表明:从整体看,零式果枝类型海岛棉纤维总糖量、晶区取向参数均优于长果枝类型;纤维总糖量、晶区取向参数具有中段优势的空间分布特点;葡萄糖+纤维二糖对晶区取向参数少(?)、φ有较显著的正向作用;纤维总糖量通过三个晶区取向参数对纤维比强度有大的负向间接作用,从而抵削了它对纤维比强度的正向直接作用,使其总作用呈负效应;Len、(?)角、纤维总糖量是影响海岛棉纤维比强度的重要性状指标.这对指导海岛棉高强育种和调控纤维发育以提高纤维比强度有重大意义.
The analysis of water-soluble total sugar content, water-soluble sugar content, microstructure parameters and fiber specific strength of 40 varieties (lines) of island cotton showed that the total sugar content, The orientation parameter of crystal zone is better than that of the long branch. The fiber total sugar content and orientation parameter of the crystal zone have the spatial distribution characteristics of the mid-range advantage. The orientation parameters of glucose + cellobiose on the crystal orientation zone are less (?), Φ is more significant positive The total sugar content of fiber through the three crystal orientation parameters of the fiber has a strong negative indirect effect on the strength, thus offset its fiber strength and direct effect on the direct effect of its total negative effect; Len, (?) Angle, the total sugar content of fiber is an important trait index that affects the specific strength of island cotton fiber, which is of great significance to guide the high-density breeding of island cotton and regulate the fiber development to improve the fiber specific strength.
