Abstract

The effectiveness of GA3 in inducing floral-bud initiation in Impatiens balsamina under non-inductive photopcriods varies considerably at different parts of the year and appears to be determined by the prevailing temperature conditions. The period of floral-bud initiation is shortest in october and february and increases both with decreasing temperatures in november and with increasing temperatures in august and september. Floral buds do not initiate in March and April, during which time the temperature increases considerably subsequent to the start of experiment.
