Zimmermann and Hitchcock1 found 2.3.5-tri-iodobenzoic acid to be active as a 'formagen', that is, a substance affecting flowering and growth processes in the tomato. In the Avena coleoptile standard test, this compound acts as an anti-auxin2, inhibiting the action of indole-3-acetic acid. The present communication deals with the influence of 2.3.5-tri-iodobenzoic acid on the growth of root hairs, these organs being used as a test object to investigate the growth of a single cell and the growth and structure of cell walls.
