Growth data of 3 year old from introducted 5 species and 23 provenances among Casuarinaceae in Guangdong was analyzed. The result showed significant growth distinction between species, provenances in a species. Interaction between sites and species was significant. Evaluated with survival percent and I value based on height, ground diameter(or breast diameter) and crown width, there were relative adaptability for 5 species. The species included Casuarina cunninghamiana ssp. cunninghamiana and C. collina, and the provenances included CK, 13521, 15574, 13516, 15004, 13520, 15002 and 15941 were founded to be fast growing, better survival percent as well. The CK of Fujian, China was the best. So both introduction and using domestic provenances were needed
