Abstract
For years, man has been trying to find a single chemical that triggers flowering in plants. Although this single chemical has not been found, several of the gibberellins show promising results as an active florigen - such as GA5 and GA6 and possibly GA1 and GA4. Results have shown that these GAs seem to travel intact from the leaf to the shoot apex just after a single long day photoperiod. gibberellins also seem to accumulate in sufficient amounts to trigger flowering. gibberellins have also been shown to cause petiole elongation. Much research still needs to be done to draw definite conclusions about the role of gibberellins as a florigen, but much of the evidence looks promising.
