Abstract: To improve new root quality of lignified cuttage of bougainvillea glabra, culture strong seedling, and discover suitable cuttage method, the effects of different rooting agent, dosage, substrate on rooting rate, number, weight, and survival rate of transplantation were surveyed. At the same time, air temperature and humidity were monitored. The results showed following rules. When woody branch was immersed into mixture of 100 mg/L GGR-6 and 750 mg/L IBA for 15 minutes, and cultured in sand with conditions of 25-40℃ air temperature and 97% humidity in early growth period. Average rooting number, rate and survival rate of transplantation of cuttage reached 107, 98% and 96% respectively. Rooting rate dose not related with survival rate of transplantation. As evaluation indexes of rooting effect of cuttage seedling, root number, weight extremely significantly related with survival rate of transplantation.
