Abstract

A method of sampling twigs and branches of trees for moisture content, under conditions such that tension exists in the xylem, is described. Samples from branches of four species of trees obtained by cutting both ends of the sample simultaneously had significantly higher moisture contents than adjacent samples from the same branch obtained by cutting one end fifteen to thirty seconds later than the other end. It is recommended that, when twig segments are to used for moisture content samples under conditions such that tensions exist in the wood, both ends of the segment be cut simultaneously.
