| Abstract: |
| Effects of three plant growth regulators including ABT，IBA，NAA on growth and development ofSophora flavescens Ait. were studied. The seedlings were treated by different concentrations and soaking time of threeplant growth regulators. The agricultural characters of annual S. flavescens like fresh weight of aboveground andunderground parts，plant height，leaf area，diameter and length of root，small section yield，were estimated and evaluatedcomprehensively. The results showed that the effects of ABT，IBA，NAA with different concentrations and soaking time，on growth and development of S. flavescens were different. The effect of 50 mg/L ABT soaking 12 hours ranked the first，with the survival rate of S. flavescens slightly higher than that of the control，the growth of aboveground and undergroundparts was significantly promoted by 50 mg/L ABT soaking 12 hours，and the fresh weight of root increased by 113.97% insmall section yield per 0.5 m2. The treatment of 50 mg/L ABT soaking 12 hours could be used as measure for increasingproduction of S. flavescens. |
