Gibberellins and auxins are the only hormones known that promote growth in oat (Avena sativa) stem segments, but when applied together, indoleacetic acid inhibits gibberellic acid-induced growth appreciably. This study shows that in addition to this inhibitory role, indoleacetic acid shortens the response time of the tissue to gibberellic acid.
