  • A trial of 30 Acacia mearnsii provenances,13 hm2 in area,was laid out on fivesites in four southern provinces in China. The 5-year results of the trial showed there are significant differences between provenances in growth rate,tree form and bark thickness.Average volume of single-tree of 6 superior provenances are 21%～95% higher than theoverall mean,and the content of the tannin of 6 superior provenances are 2%～7% higherthan the overall mean.No significant differences were found in interactions between sitesand provenance performances,The provenances have higher stability.Lastly,6 superior provenances are selected for per site.
