Combined with the production practice, under the controllable conditions of producing greenhouse, The Armand pine cutting was exposed by varied exogenous hormones ( ABT 1, IBA, NAA ) which had different concentrations and treat methods(immersion and dipping), and the results showed that under the immersion treatment, the concentration with 50mg/L, 100mg/L, 200mg/L of ABT1, the survival rate of Armand pine cutting were higher than CK, which had significant effect with CK(P<0.05). under the dipping treatment, the treatment with varied ABT1, IBA and NAA, the survival rate of Armand pine cutting had nonsignificant effect, but under the dipping concentration treatment with 500mg/L, 1000mg/L, the survival rate of Armand pine cutting were high, which had significant effect with CK(P<0.05). In addition, treated by ABT1, under the 60 min immersion treatment condition, the armband pine cutting root rate was highest than other treatments, which the value were 88%, and had significant effect with CK(P<0.05).
