Cyclamen persicum Mill. cvs. ‘Kleine Dresdnerin’ and ‘Pastel
Gemengd’ was sprayed once with gibberellic acid when flower buds were
visible as "pin heads" and 2 weeks later in order to accelerate
flowering. Treatment with GA3 at 10-25 mg dm-3
accelerated flowering, resulted in more flowers being open at one time,
and increased plant height of both cultivars. GA3 at
50 mg dm-3 caused excessive elongation and bending of floral scapes.
Application of GA3 when flower buds are 1.2-1.8 mm long is recommended.
