Abstract
IT has been shown with isolated stem sections bearing a single bud that the development of this bud can be inhibited by indolyl-3-acetic acid (IAA) or other auxins, and this inhibition released by kinetin1. The concentrations of IAA needed are physiological, and the whole phenomenon appears identical with that of normal apical dominance. Nevertheless, the question remains as to whether the same release can be obtained in the intact plant, that is, under conditions of apical dominance sensu stricto.
