Epibrassinolide (BR) was used in this study to spray wheat plant during the booting stage and filling period. It was found that when in low concentration (0.01-0.05 ppm), BR could accelerate the movement of total soluble carbohydrates in the flag leaf during the filling period; make the soluble protein content of the flag leaf consistent; increase the developing seed activity; reduce the accumulation of free ammonia (NH3) and putrescine under the stress condition; decrease the cell membrane permeability of the functional leaves in the lower parts of wheat plant. Grains per spike and thousand-grain weight were increased, infertile spikelets reduced compared to the control. The results show that BR is effective on the improvement of wheat yield.
