| description | <p>The purposa of this work was to study the influence of fertilization on wood quality of <em>Sclerolobium</em> <em>paniculatum</em> Vogel. A homogeneous planting trial, under different levels of liming and phosphorus, was established by Embrapa-Cerrados 18 years ago in Planaltina, Distrito Federal, Brazil, tropical wood savanna region. Mechanical tests conducted were static bending, parallel compression to grain, shear strength and shrinkage. No significant differences were observed for mechanical properties or for shrinkage, which presented: ¦<em><sub>b</sub></em> = 650kg/cm<sup>2</sup>, <em>E</em> = 59.877kg/cm<sup>2</sup>, ¦<em><sub>c</sub></em> = 296kg/cm<sup>2</sup> e ¦<em><sub>n</sub></em> = 131kg/cm<sup>2</sup>. Control treatment showed highest values for shear strength and compression parallel to grain. Too many branches in all trees and also too many knots in lumber were observed. Pruning is recommended for homogeneous planting of <em>Sclerolobium paniculatum</em> to avoid knots in order to be produced wood of superior quality.</p> |
