Water adsorption and desorption processes were examined of Yezo spruce (Picea jezoensis Carr.) heated at 100 to 800°C. Their sorption properties was characterized by the parameters of the curve regressed by a logistic function. Their parameters, especially the sorption rate parameters, changed at the temperature 250°C. The parameters of adsorption and desorption differed one another in the temperature region from 250 to 700°C. It appears that a wood sample is thermally decomposed above 250°C so that micro-pores in various size create in its substances.
