School of Chinese Language and Literature, Guizhou Normal University, Guiyang 550001) Abstract: The effects of exogenous hormones on the quality and yield of tartary buckwheat grains of Weiku 1 and Qianku 6 were studied. Exogenous hormones were sprayed on the whole plant at early flower stage. The results showed that different concentrations of exogenous hormones had various effects on the yield and flavonoid content of tartary buckwheat seeds. The optimum concentrations of GA3 and IAA that improved t
