520 _a ABSTRACT The objective of this work was to study the fiber length variation, retractability and basic density, in the core-bark direction and along the heig of the red tauari wood (Cariniana micrantha Ducke). The stem was evaluated in the discs, from core to bark, corresponding to 0%, 25%, 50%, 75% and 100%. At the commercial height of the tree the evaluation was carried out in the Base, DBH, 50%, 75% and 100%. Three trees were collected and 5 discs of 12 cm of thickness were taken from each tree the heights: Base, DAP, 50%, 75% and 100%. Results indicated that the fiber length increases in the radial direction core-bark and decreases in the longitudinal direction, from base to top. The analysis of the basic density varied in the core-bark direction, with tendency to increase from the position of 50% (heartwood), then decreasing in the sapwood region. Total volumetric and linear contractions decreased in the core-bark direction. Keywords: basic density, shrinkage, fiber.
