Abscisic acid (ABA) and ethephon at optimum concentrations (0.1,1ppm) promoted rooting of preformed primordia of Morus alba L.cv.Minamisakari hardwood stem sections (cuttings). At these same optimum concentrations, ethephon stimulated the onset of new shoot elongation, rooting and defoliation, whereas ABA delayed it. At 10ppm, ABA depressed new shoot elongation and defoliation greatly and at 50ppm, inhibited bud break completely. In contrast to this, 10ppm ethephon only slightly depressed new shoot elongation but markedly stimulated defoliation.
