为探明苎麻胶质含量及其组分的基因型差异 ,以及苎麻胶质含量与原麻产量、纤维支数的关系 ,以 2 5份苎麻品种为材料 ,对原麻胶质含量及其组分进行了系统分析 .结果表明 :苎麻不同基因型间胶质含量存在明显的差异 ,其变异幅度为 2 3.94%～ 37.83% ,极差达 13.89% ,变异系数为 10 .96 % .苎麻胶质各组分中 ,以半纤维素的含量 (14.0 8% )最高 ,其余依次为水溶物 (7.90 % )、果胶质 (4 .35 % )、木质素 (1.2 4% ) ,而其变异系数则以木质素最大(31.45 % ) ,其余依次为果胶质 (14.71% )、水溶物 (10 .76 % )、半纤维素 (10 .6 5 % ) .苎麻胶质总含量 (y)与其脂腊质(x1 )、水溶物 (x2 )、果胶质 (x3)、半纤维素 (x4)、木质素 (x5 )的最优回归方程为 y =0 .2 86 + 0 .946 x2 + 1.0 48x3+0 .987x4+ 1.0 43x5 .
In order to find out the difference of the genotypes of ramie gelatins and their components and the relationship between the ramie glia and the yield of raw hemp and fiber count, 25 ramie cultivars The results showed that there was a significant difference in the content of glial between different genotypes of ramie, with the range of variation ranging from 2.94% to 37.83%, the difference being 13.89% and the coefficient of variation being 10.96% Among the components, the content of hemicellulose was the highest (14.0 8%), followed by water soluble matter (7.90%), pectin (4.35%) and lignin (1.2 4%), while the coefficient of variation (31.45%), followed by pectin (14.71%), water soluble (10.76%) and hemicellulose (10.56%) .The total content The optimal regression equation for the lipids x1, x2, pectin (x3), hemicellulose (x4) and lignin (x5) was y = 0.266 + 0.946 × 2 + 1.0 48x3 +0 .987x4 + 1.0 43x5.
