摘　　要：３０个黑荆树国内外种源，在我国南方四省（区）５个点营造了１３ｈｍ２种源试验林，５年生时的调查材料分析结果表明：不同种源生长、发育、通直度、树皮厚度、单宁含量、抗性等性状差异显著。各试点６个入选种源的平均单株材积，比总体平均值大２１％～９５％，单宁含量比总体均值高２％～７％，种源与地点的互作不显著，说明种源表现具有较高的稳定性。根据生长量、产皮数量与质量、抗逆性及种源稳定性等指标，综合评定出６个适合在我国黑荆适生范围推广的优良种源。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 aresignificant 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 superiorprovenances are selected for per site。
