title: Indoleacetic acid enhancement of the inhibition of Lemna growth caused by abscisic acid.
abstract: Indoleacetic acid substantially increased the inhibitory influence of abscisic acid on growth measured on fresh weight basis of Lemna gibba L. A similar synergistic action was obtained with indolebutyric acid while neither naphthylacetic acid nor 2,4-dichlorophenoxyacetic acid showed any synergism. The antiauxin para-chlorophenoxy-isobutyric acid did not counteract the synergistic action of IAA and ABA. The results indicate that the enhancing effect of IAA on the ABA action is not a typical auxin effect.
