摘要
用凯氏定氮和分光光度法分别对9个四倍体及其对应的二倍体苦荞品系种子蛋白质含量和黄酮含量进行了比较研究。结果表明:四倍体苦荞种子蛋白质含量平均为17.21%(变化范围为15.1%～19.4%),极显著高于二倍体种子蛋白质含量(平均为13.97%,变化范围为12.9%～15.9%);四倍体苦荞种子黄酮含量平均为3.64%(变化范围为3.12%～4.57%),极显著高于二倍体种子黄酮含量(平均为2.77%,变化范围为2.42%～2.98%)。相关分析显示,二倍体与四倍体苦荞之间黄酮含量和蛋白含量均无显著相关性。
The seed protein content and seed flavonoid content between 9 diploid tartary buckwheat accessionsand their tetraploid lines were studied comparatively by means of kjeldahl determination and spectrophotometry. The results showed that tetraploid tartary buckwheat had the average protein content of 17.21% with the range of 15.1% -19.4% ,significantly higher than their diploid parents 13.97% with the range of 12.9% - 15.9%. Meanwhile, the tetraploid tartary buckwheat had the average flavonoid content of 3.64% with the range of 3. 12% -4.57%, also significantly higher than their diploid parents （2.77%） with the range of 2.42% - 2. 98%. The correlation analysis showed that there was no siginificant relationship of flavonoid content and protein content between diploid and tetraDloid tartary buckwheat
