Abstract
Boyd (1972) reviewed the various older theories as to the origin of growth stresses in trees (Martley 1928, Koehler 1933, Münch 1938, Clarke 1939, Jacobs 1945, Wardrop 1965). He then returned to his earlier hypothesis that “the generation of stresses was caused by swelling of the cell due to changes in the cell wall during differentiation”. Watanabe (1965) also took this position and laid special emphasis on the role of the microfibril angle in the S2 wall in influencing the extension or contraction of the cell, but he noted that tension wood was an exception. Boyd (1972) proceeded to develop a mathematical-mechanical model for these anisotropic cell wall mechanisms which will be considered in the next section.
