Abstract
Wood rays of beech trees were isolated with the aid of a new kind of millin g technique, and their strength was directly measured using microtensile te sting. The unexpectedly high tensile strength of approximately 75 MPa in dr y conditions leads to the supposition that, besides the known physiological functions of substance storage and conduction, the ray parenchyma also mak es a contribution to the biomechanics of living trees which has been previo usly underestimated.
