OLIVEIRA, Elisabeth de et al. Anatonical structure and charcoal quality of Mimosa tenuiflora (Willd.) Poir. Wood. Rev. Árvore [online]. 2006, vol.30, n.2, pp.311-318. ISSN 0100-6762.

The objective of this work was to determine anatomical characteristics, and dimensions of fibers, vessels and parenchyma and ray cells of Mimosa tenuiflora (Willd.) Poir wood. Fibers wall fraction, the percentage of fibers, vessels and ray and parenchyma cells, as well as density and charcoal production and properties were determined. The wood of Mimosa teniflora presents predominantly solitary, geminated and multiple porous in radial groups; porous distributed in uniform diffuse porosity; axial parenchyma paratracheal vasicentric, confluent vasicentric, aliform and confluent aliform; multiseriate, biseiat rays and, less frequently, uniseriate ones; very short fibers with thick walls. Charcoal yield was 39.68% with a 0.51g/cm3 density, 71.79% carbon content and 6886cal/g calorific value.

Keywords : Mimosa tenuiflora; wood quality; anatomical characteristics; charcoal properties.
