I have posted this topic, as the earlier one sent to the Naked Scientist was misinterpreted !
I know that giberellin induces elongation of the internodes of a stem , bolting.
Also i have learnt that a flower is just a specialized part of the stem !
So what happens to the internodes of the flower when giberellin is given to it ?

If you give giberellin to a plant that is already flowering the flowers look fine, they don't seem to look much different. 

 However, there are some studies that show that giving giberellin to cut flowers (through the stem or by brushing it on them) will make them last longer.  Just looking quickly at some of these papers it looks like that really depends on the type of flower.  In one paper they show that it makes one type of rose last longer, but has no effect on another type of rose.   

I hope this answers your question this time,
Colleen
