摘要：

以不同产地的30份苦荞资源为试验材料，测定了其籽粒中的总膳食纤维、不可溶性膳食纤维及可溶性膳食纤维的含量。结果表明：30份苦荞资源的总膳食纤维含量变化的幅度为4.61%~40.95%，平均值为17.18%；不可溶性膳食纤维含量的变异幅度为3.36%~31.08%，平均值为9.65%；可溶性膳食纤维含量的变异幅度为0.92%~17.51%，平均值为7.53%。苦荞中膳食纤维含量较高，以不可溶性膳食纤维为主。不同产地的苦荞种子中总膳食纤维、不可溶性膳食纤维、可溶性膳食纤维含量存在差异。此研究结果对进一步研究膳食纤维含量在不同苦荞资源间的遗传变异规律具有重要意义。

Abstract:

Used 30 kinds of tartary buckwheat as experimental material to determine the total dietary fiber content, insoluble dietary fiber and soluble dietary fiber content. The results showed that, total dietary fiber of 30 kinds of tartary buckwheat was change between 4.61%-40.95%, with an average of 17.18%. The insoluble dietary fiber content of 30 kinds of tartary buckwheat was change between 3.36%-31.08%, with an average of 9.65%. The soluble dietary fiber content of 30 kinds of tartary buckwheat was change between 0.92%-17.51%, with an average of 7.53%. The dietary fiber content was higher, mainly with insoluble dietary fiber. There was difference among different origin of tartary buckwheat. This study had important significance for further study on the genetic and variation law of dietary fiber content between different tartary buckwheat resources.
