A₀, A₁, and A₂ are the control, moderate thinning, and heavy thinning regimes, respectively.
B₁, B₂, and B₃ are low pruning, medium pruning, and high pruning, respectively.
Mean marked with different superscript letters are significantly different at α = 0.05.
No significant difference at α = 0.05.
