Seasonal Water Content and Distribution in Eastern White Pine
1969
Linzon, S. N.
Studies over a 30-month period revealed the presence of a seasonal rhythm in water content in the sapwood and in wet and dry portions of the heartwood of eastern white pine, Pinus strobus L. The data, indicated an increase in water content in late autumn and early winter, a drying out in late winter, a slight increase in the spring, fluctuations during the summer strongly influenced by weather, and a slight decrease in early autumn prior to the increase at the end of the year. The newest parts of the crown were the wettest in the tree. Outer rings in the sapwood of the crown were wetter than those in the bole and butt. Wet heartwood possessed as high a water content as sapwood, whereas dry heartwood contained the lowest water content of all the parts of the tree examined.
