Abstract
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.
