不同原产地苦荞种子中可溶性糖含量的比较

Comparison of Soluble Sugar Content in the Seeds of Tartary Buckwheat from Different Habitats

[目的]研究不同原产地苦荞种子中可溶性糖的含量差异。[方法]以不同原产地的35份苦荞样品为试验材料．采用比色法测定了其籽粒的可溶性糖含量。[结果]不同原产地的35份苦荞样品中的可溶性糖含量变化范围为7．23％～9．96％，平均值为8．17％；其中以贵州威宁产苦荞种子T374中可溶性糖含量最高，达9．96％；贵州威宁产种子苦荞T330中可溶性糖含量最低，为7．23％。[结论]该研究为苦荞植物资源的种植栽培和质量控制提供了科学依据。

[Objective] To investigate the variation of soluble sugar content in the seeds of Tartary Buckwheat from different habitats.[Method] 35 kinds of buckwheat were as experimental materials,and the soluble sugar content of the seeds in which were determined by colorimetric method.[Result] The variation range of soluble sugar content in different kinds of buckwheat was from 7.23 to 9.96% with the average of 8.17%.The T374 seed from Weining of Guizhou had the highest content of soluble sugar（9.96%）,while the T330 seed from Weining was the lowest one in soluble sugar contet（7.23%）.[Conclusion]The study provides scientific basis for the cultivation and quality control of Tartary Buckwheat.
