Abstract: The effects of different treatments on the survival of twigs and hard branches cuttings of Idesia polycarpa Maxim. were analyzed. The results showed that the concentration of plant growth regulators, the position of cuttings and the types of plant growth regulators were the main factors affecting hard branches cutting. The effect of plant growth regulator concentration on the survival rate of twigs cuttings was very significant. The cutting direction, cuttings location and plant growth regulator types had significant effects on the survival rate of twigs cuttings, while the other factors had no significant effects. Under completely closed condition, 200 mg/kg NAA was used to treat the twigs of Idesia polycarpa Maxim., and the survival rate of cuttings was the highest.

Key words: Idesia polycarpa Maxim., cuttings, twigs, hard branches, survival rate
