苦荞种子中硒含量的基因型差异研究

Study on Se Content in Different Genotypes of Fagopyrum tataricum

[目的]筛选出硒含量较高的苦荞资源。[方法]以不同产地的35份苦荞资源为试材,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0.009 9~0.120 8 mg/kg,平均值为0.040 6 mg/kg;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] To select the Fagopyrum tataricum with higher Se content.[Method] Se contents in 35 Fagopyrum tataricum materials from different places of origin were detected.[Result] Se content in the 35 Fagopyrum tataricum materials ranged from 0.009 9 to 0.120 8 mg/kg with an average of 0.040 6 mg/kg;it varied from region to region,the Se content in the Fagopyrum tataricum materials from Gansu was the highest while lower in that from Nayong of Guizhou and Shaanxi.[Conclusion] The research provided theoretical support for further studying the genetic variation laws of Se content in different Fagopyrum tataricum materials.
