摘要
[Objective] The aim was to determine the difference in sucrose content of different tartary buckwheat sources,so as to screen low-sucrose buckwheat materials.[Method] The sucrose contents of 35 tartary buckwheat materials from different regions were measured.[Result] The sucrose content of the 35 tartary buckwheat materials varied from 0.007 7% to 0.208 9% with an average of 0.051 8%.There was some difference among the tartary buckwheat materials from different regions.The seeds from Hezhang in Guizhou had higher sucrose content,while the seeds from Nayong in Guizhou had lower sucrose content.[Conclusion] The content of sucrose was significantly low in tartary buckwheat,which could be popularized as a kind of low-sugar crop.
[目的]明确不同苦荞资源间蔗糖含量的差异,筛选出低蔗糖含量的苦荞材料。[方法]测定了以不同产地的35份苦荞籽粒中的蔗糖含量。[结果]35份苦荞资源的蔗糖含量变化幅度为0.0077%-0.2089%,平均值为0.0518%;不同产地苦荞的蔗糖含量存在差异,以贵州赫章地区较高,贵州纳雍地区较低。[结论]苦荞中蔗糖含量较低,可作为低糖粮食作物进行推广利用。
