This study focused on the use of evapotranspiration as a means of drying wood. This principle is based on the fact that tree species with outstanding sprouting capacities are able to leaf after being felled and are physiologically active until they have enough water. The course of wood drying (the stems and branches) was examined in relation to their subsequent foliage creation and ongoing evapotranspiration, and how those factors related to other factors (temperature and precipitation). As for stems, the drying process proved to be more effective in samples with buds and less effective in samples without buds. As for branches, the samples with buds had a slightly higher weight in the long-term average, but during the sprouting season their drying was more efficient. These findings may help achieve more efficient handling of the timber from fast-growing species in relation to their processing and storage.
