Abstract: To investigate the effect of different concentrations and times on the rooting capacity of Parthenocissus thomsoni cuttings, they were treated by 100 mol/L, 300 mol/L, 500 mol/L IAA for 1 h or 2 h for measuring the rooting percentage of callus and cortex, the increment of root growth, the length of root, the amount of roots and survival rate of cutting. The results showed that the rooting rates of cutting treated by different concentration IAA for different time were higher than the control group, and  P. thomsoni cuttings treated by  300 mol/L IAA for 1 h was the best treatment. In this condition, the survival rate of cutting was the highest and plant growth was the best. These results were available for reference as rooting of P. Thomsoni treated by indoleacetic acid.
