Resumen
Basic information about growth rate and response to silvicultural treatments on potential native species are bottlenecks
for the wide use of these species for forest production. In this context, the objective of this work was to evaluate
the silvicultural performance of four native species as a function of pruning intensity. The experimental design
was completely randomized with ten replications and one plant per plot, in a 4 x 4 factorial scheme, four forest
species, and four pruning intensities. At 30 and 42 months, height (H) and diameter at breast height (DBH) were
evaluated, then the current annual increment (CAI) was calculated, as well as the mean annual increment (MAI) at
42 months. Guazuma ulmifolia showed higher growth in height and DBH compared to other species at both ages.
The pruning resulted in a reduction of MAI in 0.15 cm. year-1 in DBH for every 25% of pruning intensity.
