Abstract: Wood anatomical properties (e.g. pith opening and pore size) influence joint strength. However, information on specific tissues and fibre morphology and their effect on wooden furniture joint strength is scanty. The linear relationships [using the Pearson Product-Moment Correlation Coefficient (r)] between the tissue proportions and fibre characteristics of Entandrophragma cylindricum sapwood and heartwood and the strength of their mortise-tenon joints were studied. Fibre proportions had the greatest positive linear association with joint strength (heartwood: r = 0.991; sapwood: r = 0.975), while vessels and axial parenchyma proportions in the heartwood and sapwood respectively had the greatest negative relationships with joint strength (r = -0.986 and r = -0.962 respectively). Fibre diameter had the greatest positive influence on joint strength [r = 0.996 (heartwood); r = 0.994 (sapwood)] followed by fibre double-wall thickness (r = 0.990 and 0.993 respectively) and fibre length (r = 0.968 and 0.992 respectively). However, fibre lumen diameter negatively correlated with joint strength [r = -0.987 (heartwood); -0.978 (sapwood)]. Thus, wood with more fibres, which have large diameters but small lumen, could produce joints with greater strength than those with more vessels and axial parenchyma.
