Trunk injection of paclobutrazol (Clipper) significantly increased the bud crop on 7-year-old Eucalyptus globulus (Labill.) seed orchard trees, within one year of application. This is the first reported stimulation of reproduction to occur, with eucalypts, in the season of application. Ethephon (Ethrel), daminozide (Alar) and daminozide combined with ethephon, had no significant effect on bud production. Paclobutrazol combined with ethephon produced similar effects to the paclobutrazol treatment.
