Effects of Different Hormone Treatments on Cutting Propagation in Homalium hainanense
[ Objective] The aim was to study appropriate hormone and concentration for cutting propagation in Homalium hainanense, to pro-vide scientific method and basis for cultivation. [ Method] With ephemeral H. hainanense as test material, setting up 4 hormones( IAA, IBA, NAA, ABT strong rooting powder) and 5 concentrations(50, 100, 200, 500, 1 000 mg/L), effects of different exogenous hormones and suit-able concentration on cutting propagation in H. hainanense were studied. [ Result] 500 mg/L IAA and 200 mg/L IBA was top 2 optimal treat-ments, the average survival rate was 83. 33% and 80. 0% respectively. In aspect of promoting branches growth, 500 mg/L IAA treatment group was better than other test groups with average lateral bud number 28. 33 and pplant height 49. 78 cm. [ Conclusion] 500 mg/L IAA could be used for cutting propagation in H. hainanense.
