| This work aimed the anatomical description of Melaleuca leucadendron wooden. The study was conducted from an individual tree collecting three discs for confection of histological slides and macerated. Was used to mashing nitric-acetic method and for histology was used simple staining with 1% safranin. The wood anatomy agrees in general aspects to the typical pattern of Myrtaceae Family: flocking diffuse porosity, solitary pores, simple perforation plates, besides paratracheal axial parenchyma linear aliforme, very numerous rays and heterocellular, pits-ray vascular parenchyma-vascular and fibrous tissue composed of prominent fibrotraqueoids, very short fibers, distinct growth rings of walls marked by the end of the fibers flattened latewood. Qualitatively... |

| This study aimed to evaluate wood physical properties of Pinus patula, aged 38, from a forest stand located in Machipanda, central region of Mozambique. Determination of physical properties, such as basic specific gravity, shrinkage, and moisture content of wood in the pith-bark followed the recommendations of the Panamerican Standard - COPANT. Results showed statistically significant differences at significance level of 5%, in the radial direction for the shrinkage coefficient in the pith-bark. Radial and tangential shrinkage values were 6.06 and 8.80% in juvenile wood and 6.18 and 8.65% in adult wood, respectively, with anisotropy coefficient of 1.43 for juvenile wood and 2.44 for adult wood. Pinus patula growing in Inhamacari forest shows stable wood... |
