Root growth and gravireaction: endogenous hormone balance

Part of the Developments in Plant and Soil Sciences book series (DPSS, volume 4)

Abstract

The role originally ascribed to indolyl-3-acetic acid (IAA) in the classical hypothesis first proposed by Cholodny [1] and Went [17] has been filled — for root growth and gravireaction — by abscisic acid (ABA) which could be considered [4, 18] as one of the endogenous growth inhibitors [16] produced (at least for maize roots) by the cap cells and moving in the basipetal direction [4–8; 19, 20].
