Mean tree height (a) and basal area (b) of Acacia mangium and Eucalyptus grandis in the monospecific stands (100A and 100E, respectively) and the mixed stand (50E:50A–Acacia/50E:50A–Eucalyptus). Vertical bars indicate standard deviations between blocks (n = 3). No statistical differences were found between blocks (P ≥ 0.3). For a given date, different letters indicate differences between treatments (p < 0.05)
