| Abstract: | By applying optimal saturation D design,the effects of ultrasonic waves and gibberellie acid on germination of Rheum tanguticum were investigated.The results showed that ultrasonic waves and gibberellic acid could increase germination rate and ultrasonic waves was the main factor.The optimized combination of the two factors was ultrasonic waves between 21.6 and 43.1 min and gibberellic acid concentration between 38.2 and 58.9mg/kg. |
