为了揭示苎麻基因型之间胶质及其组分的时空变化规律 ,促进苎麻高产优质低胶育种与栽培 ,对 2 5个苎麻品种不同季别、不同部位的原麻胶质含量及其组分的测定结果表明 ,苎麻胶质及其组分存在明显的时空差异 .不同季别的总胶质、果胶质、半纤维素的含量均以头麻最高 ,二麻次之 ,三麻最低 ;水溶物、木质素的含量大小恰好相反 .不同部位的总胶质、水溶物、果胶质、半纤维素的含量均以梢部最高 ,基部次之 ,中部最低 ;木质素的含量则以基部最高 ,中部次之 ,梢部最低 .苎麻胶质及其组分时空差异的大小又因品种而异 :苎麻总胶质以竹子麻、大庸黄壳麻、青壳麻、四川珙县圆麻、湘潭大叶白的变异较大 ,达 4.19%～ 5 .95 % ,沅江白里子青、湘苎三号等 6个品种的变异幅度较小 ,在 1.0 0 %～ 1.99%之间
In order to reveal the temporal and spatial variation of glia and its components in ramie genotypes, and to promote high-yield, high-quality and low-gluten breeding and cultivation of ramie, the effects of different seasons and parts of 25 ramie varieties on the content and components The results showed that there were obvious spatiotemporal differences between glia and its components.The content of total glia, pectin and hemicellulose in the different seasons were the highest in the first, the second and the lowest in the second, Soluble matter, lignin content of the size of the opposite.In different parts of the total glial, water-soluble, pectin, hemicellulose content are the highest tip, the base followed by the middle of the lowest; lignin content in the base The highest in the middle followed by the lowest in the shoot.The difference of space-time between the ramie gum and its components varies with the varieties: the total gum of ramie is composed of bamboo hemp, dwarf yellow hump, green shell hemp, , The variation of the big white leaves in Xiangtan was larger, reaching 4.19% -5.95%. The variation range of 6 varieties such as Yuanjiang white Liziqing and Xiangzhu 3 was relatively small, ranging from 1.0 0% to 1.99%
