摘要
[目的]筛选出硒含量较高的苦荞资源。[方法]以不同产地的35份苦荞资源为试验材料,测定了其籽粒中的硒含量。[结果]35份苦荞资源的硒含量变化幅度为0.0099-0.1208mg/g,平均值为0.0406mg/g;不同产地苦荞的硒含量存在差异,以甘肃地区较高,贵州纳雍和陕西较低。[结论]为进一步研究硒含量在不同苦荞资源间的遗传变异规律提供了理论依据。
[Objective]The aim was to screening the tartary buckwheat resources with higher Se content.[Method]35 accessions of tartary buckwheat resources were used as experimental materials,and the Se content of seeds were determined.[Result]The Se content of 35 kinds of tartary buckwheat will change in a range of 0.009 9 to 0.120 8 mg/g with an average of 0.040 6 mg/g.There was difference among tartary buckwheat from different origins.The seeds from Gansu had the highest content of Se,while the seeds from Nayong in Guizhou and Shaanxi had a lowest content of Se.[Conclusion]The study had important significance for further study on the genetic and variation law of Se content between different tartary buckwheat resources.
