Abstract

Effects of pruning on growth ring thickness and density were studied in young trees of Pinus taeda L. A reduction in growth ring thickness and an increase in density were found only in the first year after the most severe pruning, in which branches were removed up to 3,0 m height. Pruning had no effect on wood density in the following years. On the other hand, there was a significant increase in ring thickness after the initial reduction in the first year, suggesting the existence of a negative trophic balance in the lower branches. If properly applied, pruning can improve both growth process and wood quality of the main stem.
