[Objective]To provide technical support for breeding of Nanocnide lobata by screening the optimum concentration of IBA.[Method]With rooting rate,adventitious root amount,root length,lateral root number and developing index of root as indicators,the root situation of Nanocnide lobata cuttings treated with IBA at the concentration of 0,30,60 and 90 mg/L and treating time of 2,4 and 6 h were tested respectively.[Result]The results showed that the appropriate concentration and soaking time of IBA were 60 mg/L and 6 h respectively,under which the lateral root number,adventitious root number,adventitious root length and the developing index of root were 16.6,48.6,15.8 mm and 424.9 respectively.[Conclusion]The study is of great importance in instructing the breeding of Nanocnide lobata.
