Thus, the aim of this study is to determine wood basic density and average carbon content in young <em>Tectona grandis</em> trees grown in commercial plantations in southeast Pará. Study subjects were between four and five years old. Samples, in the form of wood discs taken at 1.3 m height from soil, were separated into bark, heartwood, and sapwood, considering two types of genetic material: clones and seeds. Basic density varied, on average, from 0.46 g cm<sup>-3</sup> in sapwood to 0.49 g cm<sup>-3</sup> in heartwood, and no significant difference was observed between genetic materials. Average carbon content varied from 36% in the bark to 44% in the wood, and significant differences were found between averages of the two materials. There was no significant corre­lation between basic density and carbon content (r=0.3147). It was concluded that heartwood formation has early occurrence in teak, but there are no significant basic density differences between sapwood and heart­wood. However, there are carbon content differences between wood and bark in the ages analyzed.</p>}, number={4}, journal={Científica}, author={Sanquetta, Mateus Niroh Inoue and Sanquetta, Carlos Roberto and Mognon, Francelo and Corte, Ana Paula Dalla and Maas, Greyce Charllyne Benedet}, year={2016}, month={nov.}, pages={608–614} }
