Crescimento de Tectona grandis (Teca) em sistema silvicultural de talhadia composta em Minas Gerais

Abstract

The unstoppable search for wood for both energetic and noble use (saw timber) has found in exotic species, such as eucalyptus, pinus and teak, an alternative to supply this increasing demand. The reforestation industries have obtained great success with investments on those species, since they present desirable economic return, high quality products which provide the required objectives and are an alternative for minimizing the advancements on our natural forests. Teak is a species of great height, with harvesting cycle of 25 years in Brazil and presents wood as its main product, widely used in boat coating. Currently, several studies on teak have been conducted with the aim to supply the frequent doubts about its behavior and growth dynamic, as much as silviculture techniques and practices that should be used in order to reach successful planting of this species. Teak is characterized as a heliophilous species, which does not tolerate shadow. However, it presents great capacity of stump sprouting. In this context, the general objectives of this work are to evaluate the capacity of stump sprouting under compound coppice process and the interaction between thinning x spacing on the growth dynamic of this species in the northwest region of Minas Gerais.
