Abstract
Gibberellic acid /GA3/, 6-benzylaminopurine /BA/ and 
-naphthaleneacetic acid /NAA/ were injected into 5°C bulbs at the time of planting at 15°C. Ethephon was sprayed on the plants at the onset of flowering.
GA3 reduced forcing-time, increased the number of bulblets, but decreased their size.
BA and NAA did not affect forcing-time, number and size of bulblets.
A lower number of bulblets from BA-treated bulbs formed flower buds.
Flower buds were not induced in bulblets from ethephon-treated plants.
