Abstract

SILVA, Gilson Fernandes da et al. Income and loss in rolling of Paricá wood in the region of Paragominas, Pará state. Ciênc. Florest. [online]. 2015, vol.25, n.2, pp.447-455. ISSN 0103-9954.  https://doi.org/10.5902/1980509818464.

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

Keywords : forest biometric; Schizolobium amazonicum; merchantable volume.
