Effect of Ecological Environment on Flavonoids Content of Tartary Buckwheat

摘要

In this paper, flavonoids content of tartary buckwheat cultured in different ecological environments was determined. The results showed that flavonoids content increased then declined in the whole growth period and its maximum was observed in the flowering and seed-setting stage. Among all the trial locations, the highest flavonoids content of tartary buckwheat was observed in Zhaojue with an average of 4.60%, followed by that in Ganzi, and the lowest flavonoids content was observed in Zhangbei with an average of 3.24%. In general, the flavonoids content of tartary buckwheat cultured in the southern part of China was higher than that cultured in the northern of China.
