Table 2 Mean value and standard error of aboveground, stem, foliage and branch biomass (Wab, Wstem, Wf, Wb,respectively), tree height (H), crown length (Hc), basal area weighted mean branch length (Hb), crown ratio (r) and slenderness (H/D) by age groups, and their F and p values. Significant difference (p < 0.05) from one to another is marked by the letters a, b and c. Values following each species are the sample number in each age group
