| Abstract: | Summary The boundary desorption curve of the moisture content — water potential relationship of aspen sapwood was determined at 20 °C by the tension plate and pressure membrane methods for three specimen structural orientations and four imposed water potential values. The results show that the relationship is independent of the wood structural direction considered. Also, they further demonstrate that the discrepancies observed in a previous study between the moisture content — water potential relationships obtained with specimens of different structural orientations were due to a lack of equilibrium.This research was supported by the Natural Sciences and Engineering Research Council of Canada through operating grant no.
