Gibberellins are a set of plant hormones defined not only by function, but also by structure. All Gibberellins have 19 or 20 carbon units grouped into four or five rings, and are synthesized from Acetyl CoA. These hormones are common throughout almost every plant species and regulate growth and influence various developmental processes, such as stem elongation by cell division and elongation, germination, dormancy, flowering, sex expression, enzyme induction, leaf and fruit senescence, and other processes unique to certain plant categories. Gibberellins are produced in greater masses under colder temperatures. Gibberellin production has aided in this plant’s flowering.
