Identificação de Madeiras do Cerrado utilizadas para a produção de Carvão Vegetal no Sul do Tocantins

Abstract

The Cerrado biome is known as the world's richest Savanna in biodiversity, it is considered the second biggest Brazilian biome. As technology advances, the Cerrado suffers with changes in its landscapes, therefore compromising important ecological functions. In Tocantins, for example, the Cerrado is being exploited for charcoal production, and a big part of this production is clandestine, promoting deforestation and decrease of the biome. This work’s objective is to macroscopically identify tree species' wood used for this purpose and formulate an identification key, that is of great importance since it will help wood technology professionals and students or other alike areas and allow for a more precise inspection of the species that are used for charcoal production in the south of Tocantins. The wood’s organoleptics properties and macroscopic anatomical characteristics were described and measures were taken from the tangential diameters of the pores and frequency of the pores by mm2. The identified species were Callisthene major Mart. & Zucc, Machaerium brasiliense Vogel, Palicourearigida Kunth, Magonia pubescens A.St.-Hil, Xylopia aromatic (Lam.) Mart, Byrsonima pachyphylla A.Juss., Anacardium humile A. St.-Hil., Hirtella glandulosa Spreng., Andira cuyabensis Benth and Terminalia glabrescens Mart.
