Desempenho silvicultural de Tectona grandis L. f. em diferentes espaçamentos em Cáceres, MT

Abstract

Teak meets the main criteria for selection of tree species for timber production of rapid growth. Thus choosing the proper spacing will provide the largest volume per area and stems with desirable quality. The objective of this study was to evaluate the effect of spacing in several dendrometric variables in stands of teak in Caceres, Mato Grosso state. The following variables were assessed at the ages of 11 and 16 years: diameter at breast height (DBH), total height, basal area, total volume per tree, volume per hectare, annual average growth, and survival. It was observed that the lower the density of trees, the greater the DAP and the individual volume; and that the greater the density, the greater the basal area and the total volume per hectare. Lack of thinning negatively affected the dendrometric averages and the production of stands at different spacings.
