Axial and Radial Variations in Wood Density and Moisture Of The Trunk of Afzelia africana Sm. ex Pers.
Journal Title: IOSR Journal of Pharmacy and Biological Sciences (IOSR-JPBS) - Year 2016, Vol 11, Issue 1
Abstract
Variations in the wood density (kg/m3 ) and moisture content (%) of the trunk of a fully grown specie of Afzelia africana were assessed along the radial and axial axes following recommended standard procedures. The average wood density of the trunk of the specie was assessed to be 697.34 ± 0.20 (Base), 690.78 ± 0.10 (Middle) and 740.15 ± 0.40 (Top) while the average moisture content was assessed to be 55.38 ± 0.40 (Base), 56.57 ± 0.20 (Middle) and 65.25 ± 0.10 (Top) along the axial axes respectively. There were no significant variations (P≤0.05) in both the wood density and percentage moisture between the base and the middle of the trunk. However, significant variations (P≤0.05) existed in the wood density and the percentage moisture content of this specie between the middle and top portions of the trunk. Consequently, both the wood density and percentage moisture of the trunk were high (i.e. > 540kg/m3 and > 30% respectively.) and increased with the height of the tree. On the other hand, the wood density decreased from the core to the outer portions of the trunk both at the the base, middle and top positions. This meant that the wood density decreased as the plant increased in girth. The reverse was the case for percentage moisture content which increased significantly (P≤0.05) with the girth of the trunk. The high wood density and high moisture revealed about this specie in this present assessment were tapped as base line for proposing the possible end uses of the trunk of this specie.
