Abstract: Rosewood (Pterocarpus erinaceus) is highly priced for furniture, flooring and cabinetry for its rich hue and durability. Its coppiced wood augments the timber for regular supply and sustainable utilization. Fibre morphology from macerated slivers within its coppiced and non-coppiced stems and their utilization potential were assessed. Derived ratios for the fibres were also calculated. The axial positions (butt, middle, crown) affected the fibre dimensions. Fibre length was greater for coppiced trees [i.e., 1663±11, 1488±5, 1511±10μm (for sapwood) and 1498±10, 1486±9, 1394±4μm (for heartwood)] than the non-coppiced [i.e., 1240±7, 1013±5, 1137±5μm (sapwood) and 1094±8, 1002±2, 1041±9μm (heartwood)]. In all, those for sapwoods were greater than heartwoods’. Significant differences (P˂0.05) existed between fibre lengths from the coppiced (1394±4-1663±11μm) and non-coppiced trees (1002±2-1240±7μm). Fibre diameters for coppiced sapwood and heartwood were 23±1, 20±1, 22±0.8μm and 21.5±0.3, 20.7±0.5, 21.3±2μm and noncoppiced recorded 21±0.6, 20.7±0.3, 20.6±0.1μm and 21±0, 21±0.4, 21±0.8μm respectively. Their respective double wall thicknesses were 8.4±0.2, 7.2±0.2, 9.4±1μm and 8.2±0.2, 9±0.3, 9.1±0.4μm for coppiced wood, and 9.1±1, 7.8±0.1, 8.1±0.3μm and 8.5±0.3, 8±0.4, 8±1 for non-coppiced. Thus, radial stem position also influenced fibre morphology. The fibre indices [i.e., Runkel Ratio, Slenderness Ratio and Flexibility Coefficient for coppiced wood (0.6±0.06-0.85±0.06, 68±4-77±6, 56±4-64±2 respectively) and non-coppiced (0.64±0.12-0.8±0, 49±1-58±4, 57±3-62±2 respectively)] indicate the timber’s aptness for pulp and paper. Besides, the Wood Industry could exploit the fibre characteristics of coppiced wood also for engineering of fibre-based products and structural applications.
