| description | The purposa of this work was to study the influence of fertilization on wood quality of Sclerolobium
paniculatum 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: b = 650kg/cm2, E = 59.877kg/cm2, c = 296kg/cm2 e ν = 131kg/cm2. 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
Sclerolobium paniculatum to avoid knots in order to be produced wood of superior quality. |
