title: Abscisic acid as a root growth inhibitor: Physiological analyses.
abstract: Abscisic acid (ABA) moves basipetally and laterally in maize (Zea mays L.) root segments placed horizontally; its transport properties are thus similar to those of the growth-inhibiting substances produced by the root cap. The two opposite flows af ABA and of indolyl-3-acetic acid (IAA) - substances both present in the cap - may control elongation and georeaction of the root.
