Table III
Mean values (±SE) of stem mass ratio (SMR), branch mass ratio (BMR), and leaf mass ratio (LMR) across each crown zone and for the three crown zones pooled together for control and defoliated seedlings on D27 of the experiment. LSD homogeneous groupings are identified by letters (α = 0.05).
