ABSTRACTThe aim of this study was to evaluate the performance of laminate wood paricá (Schizolobium amazonicumHuber ex. Ducke) in commercial plantations in the region of Paragominas, Pará state. Using 180 sampletrees aged five, six and seven years,originating from plantations and grown in 4 x 4 m spacing, the averageincome was evaluated, taking into account income by age and diameter class. Losses were also evaluatedthroughout the lamination process. The results show an average yield of 50.31% in the activity, which isconsistent with species ofPinusandEucalyptus. Trees that were older and larger in diameter showed higheryield and therefore lower losses due to defects and the remainder roller.
