Abstract: The cutting propagation of three tropical species of Acacia, A. mangium,A. auriculiformis,A. crassicarpa,have been tested in the field. It shows that autumn is the best season for their vegetative propagation in Guangzhou. The cuttings of them treated with rooting power,IBD 2#,can be directly put into plastic bag filled with the mixed medium of 1/3 burning earth and 2/3 deep yellow soil. In order to control temperature,humidity and sunshine,the bed must be surrounded with plastic film and shaded by sunshade net(60 percent).61.8%, 88.8% and 68.9% of the cuttings survival rate for A.mangium,A.auriculiformis and A.crassicarpa can be raised to. For A.auriculiformis,it is easier to propagate by cutting than the others,and there is less difference of rooting by season changing.
