中文摘要：

Seeds of soybeans and mung beans were soaked into five different concentrations( 0,0. 05,0. 10,0. 20,0. 30 mg / L) of natural brassinolide( NBR)solution. According to the results,natural brassinolide treatment could improve seed germination rate and hypocotyl-radicle ratio of soybeans and mung beans and promote the growth of sprouts. To be specific,seed germination rate of soybeans reached the highest in 0. 05 mg / L natural brassinolide treatment,which was improved by 25. 0 percentage points compared with the control group,and the sprout length was improved by 4. 33 cm; 0. 30 mg / L natural brassinolide exhibited the most significant promotion effect on seed germination and sprout growth of mung beans,seed germination rate was improved by 18. 3 percentage points and sprout length was improved by 7. 29 cm; hypocotyl-radicle ratio of soybean and mung bean sprouts reached the highest( 2. 96,1. 43) in 0. 05 mg / L natural brassinolide treatment.

英文摘要：

Seeds of soybeans and mung beans were soaked into five different concentrations （0, 0.05, 0.10, 0.20, 0.30 mg/L） of natural brassinolide （ NBR ） solution. According to the results, natural brassinolide treatment could improve seed germination rate and hypocotyl-radicle ratio of soybeans and mung beans and promote the growth of sprouts. To be specific, seed germination rate of soybeans reached the highest in 0.05 mg/L natural brassinolide treatment, which was im- proved by 25.0 percentage points compared with the control group, and the sprout length was improved by 4.33 em; 0.30 mg/L natural brassinolide exhibited the most significant promotion effect on seed germination and sprout growth of mung beans, seed germination rate was improved by 18.3 percentage points and sprout length was improved by 7.29 cm; hypocotyl-radiele ratio of soybean and mung bean sprouts reached the highest （2.96, 1.43 ） in 0.05 mg/L natural brassinolide treatment.
