Common giberellin is found in
Dear Student
You question is not clear and seems to be incomplete. I guess there should be some more detail. Here, is some detail about the topic.
There are more than 70 gibberellins isolated, some of them are GA1, GA2, GA3 and so on. GA3 Gibberellic acid is the most widely studied plant growth regulators.
E. Kurosawa identified gibbereilins present in a fungal pathogen Gibberella fujikuroi. It is isolated from infected rice seedlings when treated with sterile filtrates of fungus.
Gibberellins are diterpenoid acids which are synthesized in plastids and modified in the endoplasmic reticulum and cytosol until they reach their biologically-active form. It is found in growing plant tissues like shoots, young leaves and flowers.
Regards
