Trichosanthes is dioecious plant. During its cultivation, cuttings propagation is able to effectively control an appropriate proportion of male and female plants. The test studied the effects of different ABT concentration (0mg/l、50 mg/l、100 mg/l and 200 mg/l), different soaking time under 100 mg/l ABT(10min、20 min、40 min and 60 min) and different cuttings length (1 node、2 nodes and 3 nodes) on cuttings rooting rates and transplant surviving rate. The results shows that:When using perlite as matrix, the optimum condition of cuttings propagation is selecting one-year branchs with 2 nodes as cuttings and soaking them with 100 mg/l ABT for 40 minutes, under which, the 100% rooting rates and 99% transplant surviving rate of cuttings were obtained and better overall economic efficiency can be achieved.
