Abstract

Bi-weekly samples of wood were taken from two species of conifers and three species of dicots from September to April. From the samples water content and solute content of each tree were determined. From soil samples taken beneath each tree the soil moisture was determined. The water content in the dicots was high in winter and low in the fall and spring, and in the conifers it was high in the fall and decreased through the winter to low values in the spring. Soil water influenced the water content of the trees only in minor details. The solute content of the conifers was low compared with the dicots. High solute content in the dicots occurred in February after rising during the fall and winter. Tree trunks apparently did not fill with water because of the increased solute since increases in water content preceded increases in solute content.
