Thinning Intensity and Pruning Impacts on Eucalyptus Plantations in Brazil

Table 2

Treatment significance (fixed effect) and pairwise comparisons among significant treatments for periodic increment in total height (PI); dominant height (PI); quadratic mean diameter (PIDMQ); basal area (PIBA); volume per hectare outside bark (PI ha⁻¹); and volume per tree outside bark (PI tree⁻¹). values < 0.05 are bolded.
