The Tectona grandis (teak) stands out for the high productivity and quality of its wood. The ideal spacing of a tree speciesis the one that maximizes the wood ratio and improves wood quality, being therefore the main point to be considered in the researchof forest management of teak. This work verified the influence of the spacing on some physical properties of 31-year old Tectonagrandis wood and the radial variability of these properties. In this study it was used the randomized blocks with 3 treatments (3 x 1,5m;3 x 2m and 3 x 2,5m) and 5 repetitions, where 15 trees with average diameter obtained in populations of Pederneiras/SP region. Ineach tree, a disc of 7cm thick in the region of the DBH (diameter at breast height) was removed and from each disc were taken samplesin different distances in the pith-to-bark radial direction (pith, central and bark). The studied properties were: specific gravity,volumetric shrinkage and basic density. According to the results, it could be concluded that the spacing of the trees influencedsignificantly only the specific gravity, where the larger spacing differed from the minor ones. An increase of the specific gravity alsooccurred in the pith to bark direction. |
