Three Year Growth Performance of Acacia Crassicarpa Provenances at Serdang, Malaysia

A trial at Universiti Putra Malaysia (UPM) Serdang, Malaysia consisting of eight provenances of A. crassicarpa Cunn. ex. Benth. was measured at three years for survival, height, diameter, tree form, specific gravity, biomass of components, volume, form factor, and leaf area. One provenance was fr...
