Longitudinal and Transverse Variation in the Physical Properties of Wood Red Tauari Gerson Kleber de Almeida Cruz Nabor da Silveira Pio Setsuo Iwakiri 10.6084/m9.figshare.8987291.v1 https://scielo.figshare.com/articles/dataset/Longitudinal_and_Transverse_Variation_in_the_Physical_Properties_of_Wood_Red_Tauari/8987291 <div><p>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.</p></div> 2019-07-24 03:00:15 basic density shrinkage fiber
