采用营养液培养技术 ,研究B对不同B效率油菜品种细胞壁组成的影响。结果表明 ,根系细胞壁提取率及细胞壁纤维素含量高于叶片 ,果胶含量低于叶片 ,半纤维素含量和叶片差异不大。缺B使细胞壁提取率升高 ,但对根系和叶片细胞壁组成的影响不显著。不同B效率油菜品种细胞壁组成在根系和下部叶中差异不大 ,上部叶片高效品种螯合剂可溶性果胶含量显著高于低效品种 ,碱溶性果胶含量显著低于低效品种 ;半纤维素和纤维素含量及果胶总量差异不大
The nutrient solution culture technique was used to study the influence of B on the cell wall composition of rape cultivars with different B efficiency. The results showed that the extraction rate of root cell wall and cellulose content of cell wall were higher than those of leaves, and the content of pectin was lower than that of leaves. The content of hemicellulose and leaves were not significantly different. Lack of the B cell wall extraction rate, but on the root and leaf cell wall composition is not significant. The cell wall composition of different B efficiency rape cultivars was not significantly different between the roots and the lower leaves. The content of soluble pectin in the high efficiency leaves of the upper leaves was significantly higher than that of the inefficient ones, and the content of alkali soluble pectin was significantly lower than that of the inefficient ones. The content of hemicellulose and Cellulose content and the total amount of pectin little difference
