ABSTRACT Accumulation of endogenous indole-3-acetic acid (IAA) in soybean hypocotyl explants was found during adventitious root formation in naphthaleneacetic acid (NAA) and indole-3-butyric acid (IBA) treatments. The auxin-induced root formation was accompanied by increasing levels of putrescine. We suggest that the exogenously applied auxin (IBA and NAA) may act on polyamine synthase and IAA oxidase activity.
