Ocloo, J.K.Laing, E.2019-03-072019-03-072003http://dx.doi.org/10.4314/dai.v15i3.15642http://ugspace.ug.edu.gh/handle/123456789/28560The relative density (RD) and mechanical strength properties of the wood of four Ghanaian Celtis species have been studied. There were significant differences between the relative densities of the wood of the species. The wood of Celtis mildbraedii was significantly heavier (RD = 0.872) than those of C. adolfi-friderici (RD = 0.685), C. wightii (RD = 0.771) and C. zenkeri (RD = 0.789). Celtis adolfi-friderici was the lightest among the four species. There was good correlation between the relative density and some of the strength properties of the species. The wall thickness of the vessels and fibres, the fractional wall volume of the vessels and fibres of the wood were the major contributors to the density and strength of the wood of C. adolfi-friderici, C. mildbraedii and C. zenkeri.enCeltis speciesPropertiesVariationsArticle
