Steady State Growth of Avena Coleoptile Sections in High Auxin Concentrations

Abstract

The excised Avena coleoptile section constitutes a convenient system for. studying the enlargement of plant cells in response to applied auxin. A portion of the convenience lies in the fact that it has proven possible to arrange conditions such that auxin-induced extension of the section takes place at a rate which is constant with time over periods of several hours. Under these steady state conditions, the powerful methods of chemical kinetics may be applied to the analysis of the interaction of auxin with tissue (4).
