Abstract: 1) Sub-optimal concentrations of indole-3-acetic acid (IAA) added to the optimal concentration of 1:4-dihydronaphthoic acid-1 (1:4-H2-NcA) increased the elongation of etiolated pea stem sections, and the optimal concentration of IAA added to it did not cause the supra-optimal depression effect. The same was true when IAA was added to naphthaleneacetic acid (NAA).2) Sub-optimal concentrations of NAA added to the optimal concentration of 1:4-H2-NcA did not increase the elongation, and high concentrations of NAA added to it caused the depression effect.3) 3-Chloro- and 4-chlorophenoxy-isobutyric acids were antagonistic to IAA but not to 1:4-H2-NcA and NAA.4) All results are consistent with the assumption that 1:4-H2-NcA and NAA act on the same reaction site, but that IAA acts on a different site.
