Desenvolvimento quantitativo e qualitativo de tectona grandis l.f. em mato grosso

Abstract

The interest in the cultivation of teak for timber production can be demonstrated by the increase in planted area. However, studies on the development of teak are still scarce, especially in the state of Mato Grosso, where this cultivation presents a high prospect of financial return. In this study, we aimed to evaluate the quantitative and qualitative development of teak until ten years of age in the municipality of Nossa Senhora do Livramento, Mato Grosso state, Brazil. In an area divided in 73 permanent plots, we obtained the values of density, diameter at 1.3 m above the ground, total and dominant height, basal area, total volume, current annual and mean annual increments, and adjustment to regression models. We also assessed the frequency regarding the form or quality of stem and the phytosanitary status. The teak plantation studied presented quantitative development similar to or greater than those found in Asia, Africa, and South and Central Americas. The execution of thinning and pruning were the main causes of teak cultivation quality improvement.
