Abstract

The relationships between growth characteristics and wood quality has always been of interest to forest growers as well as wood processors, especially in fast-growing species. This study was conducted to examine the correlation between growth indexes and some wood properties in Acacia mangium including air-dry density (AD), modulus of rupture (MOR), modulus of elasticity (MOE), and compressive strength (CS). The results of the present study showed that diameter at breast height had a high positive significant correlation (r = 0.99; P < 0.001) with stem volume. In contrast, no significant relationship was found between tree height and stem volume. Weak cofficients of corrleration and no statistic significance (P > 0.05) were found between growth indexes with AD, MOR, MOE, and CS. The results suggests that Acacia mangium trees with faster gowth characteristics do not always produce wood of lower quality.
