Directional shrinkage decreased identically as the male variety while the volumetric shrinkage for both varieties was not consistent. However, the female recorded much swelling at the core of its mid-portion (6,23 %) and least (4,01 %) at the crown periphery. Volumetric swelling was greatest at the core of the base (6,99 %) but at least at the periphery within the middle of the male (2,89 %). Directional swelling decreased as: Radial > Tangential > Longitudinal. Unlike moisture content, density decreased towards the crowns and radially from the peripheries to their cores. Green and dry moisture content, and density were tested with the oven-dry method while swelling and shrinkage were evaluated using the water-saturation test and oven-dry methods respectively. The moisture content, density, swelling, and shrinkage within male and female Borassus aethiopum were assessed. Physical properties are major characteristics that validate biomaterials' adaptability to commercial utilization.
