The permeability to water of spruce heartwood has been measured by applying a known osmotic pressure difference across specimens in which the cell walls were water swollen and most of the void space was filled with paraffin wax. To ensure that solute molecules should not penetrate the cell wall aqu
The permeability to water of the cell wall has been measured by applying a known osmotic pressure generated by PEG 6000 across wood samples containing water-swollen cell walls. In pine the void space was filled with silicone resin with the wood at near fibre saturation point. Permeability kโข 1021 as
