title: The relationship between diffusible, extractable and conjugated (base-labile) forms of indole-3-acetic acid in isolated coleoptile tips of Zea mays L.
abstract: Isolated, 2.5-mm-long coleoptile tips of Zea mays L. cv. Anjou 210 were analyzed for diffusible and tissue-extractable indole-3-acetic acid (IAA) in comparison with the level of base-labile conjugates at various times after excision. The results indicate that base-labile conjugates of IAA do not serve as major sources of free IAA in maize coleoptile tips.
