芥蓝种质资源的营养品质分析

Physiological quality analysis on different cultivars of Chinese Kale

对56个不同芥蓝品种营养成分进行了分析和评价,测定了不同品种芥蓝的可溶性固形物(TSS)、还原糖、Vc、蛋白质、粗纤维含量。结果表明:56个不同芥蓝材料的5个营养指标的标准差分别为0.89、0.47、16.32、0.46、0.33,其变异系数分别为14.83、35.28、15.83、21.43、29.64,说明其还原糖含量的差异最大,TSS含量差异最小,为进一步的种质资源利用提供参考依据。

This study focuses on analyzing and evaluating 56 germplasm of Chinese Kale from the content of soluble solids, reducing sugar, Vc, protein, crude fiber. The result shows that the standard deviations of nutritional analysis are 0.89, 0.47, 16.32, 0.46, 0.33 respectively, and the coefficient of variation are 14.83, 35.28, 15.83, 21.43, 29.64 respectively. This indicates that the biggest difference is the Vc content, the difference of soluble solid content is minimal. This study build a good foundation on breeding a single quality trait.
