为了明确不同苦荞资源间黄酮含量的差异,以不同产地的35份苦荞资源为试验材料,在同一栽培条件下,测定了各苦荞籽粒的黄酮含量.结果表明:35份苦荞资源的黄酮含量为2.19％～4.02％,平均为3.12％；不同产地苦荞的黄酮含量存在差异,以贵州六盘水的苦荞种子中黄酮含量最高,为3.79％,原产陕西的苦荞黄酮含量最低,为2.90％.产地间总体表现为四川＞贵州＞云南＞甘肃＞陕西.研究结果基本明确了黄酮含量在不同苦荞资源间的变化规律.%Thirty-five kinds of tartary buckwheat from different areas were used as experimental material and the flavonoid content of their seeds was determined and compared under the same cultivation conditions. The result showed that the flavonoid content of 35 kinds of tartary buckwheat ranged from 2. 19% to 4. 02% with an average of 3. 12%. There was difference among tartary buckwheat from different areas. The seeds from Liupanshui of Guizhou had the highest content of flavonoid, while the seeds from Shaanxi had the lowest content of flavonoid, which was 2. 90% respectively. The order of flavonoid content was Sichuan>Guizhou>Yunnan>Gansu> Shaanxi. The study clarified the genetic variation law of flavonoid content among different tartary buckwheat resources.
