摘要
[Objective] This study aimed to finding out the difference in glucose content of tartary buckwheat seeds from different origins.[Method] Taking 35 kinds of tartary buckwheat from different origins as the test materials,the glucose content of seeds had been determined.[Result] The variation range of glucose content in 35 kinds of tartary buckwheat was from 0.055 6% to 0.840 2% with an average of 0.321 7%.There was a difference in glucose content of tartary buckwheat from different origins.The seeds T324 from Weining in Guizhou had the highest glucose content,while the seeds T398 also from Weining in Guizhou had the lowest glucose content.[Conclusion] This study provides a reference for the genetic variation law of glucose content in different tartary buckwheat resources.
[目的]明确不同产地苦荞种子中葡萄糖含量的差异。[方法]以不同产地的35份苦荞资源为试材,测定了其籽粒的葡萄糖含量。[结果]35份苦荞资源的葡萄糖含量变化幅度为0.0556%～0.8402%,平均值为0.3217%;不同产地苦荞的葡萄糖含量存在差异,以贵州威宁的苦荞种子T324中葡萄糖含量最高,原产贵州威宁苦荞种子T398最低。[结论]为明确葡萄糖含量在不同苦荞资源间的遗传变异规律提供了参考。
