Abstract

This research was carried out to assess the effect of plant spacing over "tachi-branco"growth, production, biomass allocation and wood energetic quality. The experiment was installed in forest/savanna transition area in the North region of Roraima State, Brazil in a randomized block design and five plant spacing (2 m x 2 m; 2.5 m x 2.5 m; 3 m x 2 m; 3 m x 2.5 m; and 3 m x 3 m). After 70 months trees diametric growth, biomass production and wood energy quality were evaluate. Plant spacing influenced diametric growth, volume and individual trunk biomass, but presented no influence on wood energetic qualities. The larger spacing (3 m x 3 m) was more advantageous due to higher accumulate biomass in the trunk and less plants to be planted lowering implantation costs. However, this species is not recommend in monoculture stands for energetic purposes in the studying area due to the low productivity observed.
