In order to promote the industrialization development of Ixora coccinea,Ixora coccinea ‘Apricot Gold'was used as the object to contrast the effect of different concentration of ABT1 treatments on the cutting propagation(dividing into 5 concentrations 250~1 250 mg·L~(-1)).The results showed that in the five experimental adopted treatments,the best concentration of ABT 1 for cuttings was 1 250 mg·L~(-1) with the rooting rate of 93.75%,the leaf growth rate was better than other treatments and control,and root length,root number and chlorophyll content were significantly higher than those of control.The leaf length was 3.92 cm,root length was 6.08 cm,and root number was 11.8 strips measuring at 32 days after the cutting.
