Effects of stages of architectural development (ASD 1 to 3) on leaf traits for T. melinonii (white) and D. guianensis (black). Values are least square means (± Standard error) adjusted at a common relative daily photon flux (DPFrel=26.1 %). Significant differences were tested with the multiple comparisons post-hoc test of Tukey (P < 0.05) and indicated by different letters (a, b, c for T. melinonii and a′, b′c′ for D. guianensis).
