Produção e avaliação da qualidade de lâminas de madeira de um híbrido de Pinus elliottii var. elliottii × Pinus caribaea var. hondurensis

Abstract

This work aimed to evaluate the utilization potential of wood from Pinus elliottii var. elliottii x Pinus caribaea var. hondurensis hybrid, seven years and 10 months of age, for veneer production. Wood density, peeling yield and the quality of the veneers produced from logs taken from two positions on the tree trunk were assessed: from the base (A logs) and subsequent (B logs). The wood presented low basic density (0.320 g/cm3) and proved to be easily processed in the rotary cutting lathe. The peeling yield (average based on logs without bark) was approximately 53%. The veneers graded in the C and C+ classes accounted for approximately 61% of the total obtained. The A logs yielded more veneers, but the veneers produced presented lower quality compared with those produced from the B logs. We concluded that the hybrid wood herein studied shows good potential for veneer production.
