摘　　要：黑荆树是一种生长快、用途广的树种。树皮是优质栲胶原料;木材可做矿柱和家具等;根具根瘤,可以固氮,改良土壤。中国在50年代初开始引种,目前主要种植在亚热带的中南部地区,跨经度20°、纬度10°,其垂直分布差为1500m。分布区内气候和土壤差异很大,因此,各种植区只有选择合适的种源进行造林,才能获得理想的产量。Design and conditions of the sites for the provenance trials of the black wattle (Acacia mearnsii) have been described. Variations of characters relevant to seedlings in the nursery stage and the young trees of one and a half year old were analyzed. The results were as follows:Ⅰ. There were significant differences between different provenances in height, diameter growth and biomass at nursery stage.Ⅱ. For young trees, the significant difference lies in increment of diameter and tree height.Ⅲ. Among six Chinese provenances, five ones started flowering, but no Australian provenance tested was found flowering at the same time.Ⅳ. Provenances 14725, 15087, 15088, 14397, 14771, C24, C20 and C21 appeared the best. No. C6 from Ganzhou was performing badly.Ⅴ. All provenances tested did not differ significantly for die-back incidence.
