Abstract

Foliar applications of Promalin (BA + GA_{4 + 7}), Pro-Shear (BA), Accel (PBA) or Florel (ethephon) were evaluated for their capacity to increase cutting production of geranium stock plants. After a first harvest of cuttings, the number of terminal cuttings was increased 19% by a single application of Promalin (BA + GA_{4 + 7}) or Accel (PBA) and 93% with Florel (ethephon) application when compared to an untreated control. However, after a second harvest of cuttings following a second application of the foliar spray treatments, numbers of terminal cuttings did not differ among chemical treatments and single-node cuttings increased 60–73% with the application of Promalin (BA + GA_{4 + 7}) when compared to the control.
