Abstract: | Normal, terminal inflorescences of Cordyline terminalis, a woodymonocotyledon, appeared 46 weeks after apical buds weretreated with gibberellin A3 (GA3) or GA4+7. There was no responseto GA13. Large plants, newly rooted cuttings, and seedlingsall responded, although there were clonal differences. Floweringwas induced under natural day lengths throughout the year. Untreatedcontrol plants in all experiments remained vegetative. Dracaenaspp. did not respond to the three gibberellins. |
