PRODUCTIVITY AND QUALITY OF THE Tachigali vulgaris WOOD FOR ENERGETIC PURPOSES

KEY WORDS:

BIG AREA: Ciências Agrárias

SUMMARY:

The tree species tachi-branco (Tachigali vulgaris L.G. Silva & H.C. Lima) has great potential for plantations for energy purposes. However, information about the ideal spacing for its planting is, as well as the ideal time for cutting, considering the greater production of biomass still incipient. This study aims to evaluate the average annual increment of biomass and the variations between growth rings of the basic density of Tachi-Branco wood cultivated in the Amazon in different spacings for bioenergetic purposes. The study was carried out in an experimental area of approximately 6 ha, at the company Jari Celulose SA, located in Pará. 2.5; 3.0 x 3.0; 3.0 x 3.5; and 3.0 x 4.0 m). The apparent density per growth ring was determined using digital x-ray equipment on the disc removed from the DAP. The basic density of trees was determined in different vertical positions. The forest inventory was conducted at 8 and 9 years of age of the tree. The conversion of the apparent density of the growth rings to basic density will be carried out using Pearson's correlation. Then, the annual increment of biomass of the species will be obtained by relating volume (inventory) and basic density data. The radial growth and apparent density curves will be superimposed, allowing the aggregation of information on wood quality and biomass production for energy purposes. It is hoped that this research will make it possible to detect the year in which the white tachi wood grown in different spacings has the highest possible basic density and the maximum increase in biomass.
