Abstract
IT is widely believed that the increase in cell wall synthesis which occurs when growth of plant cells is promoted by auxin is neither a direct consequence of hormone action nor a causal factor in cell enlargement, but is induced indirectly by the occurrence of cell enlargement1. A principal reason for this view is that if elongation is inhibited osmotically by mannitol, wall synthesis becomes reduced2, and promotion of wall synthesis by auxin does not occur3.
