Gibberellins are acids that are produced in the plant plastids or the double membrane bound organelles of the cells. They were discover by a Japanese botanist in 1898 who was trying to learn about a diease that infecting plants. The disease was Gibberella fujikuroi which is gibberellins.

Gibberellins have the greatest impact on the stem growth in plants. When gibberellins are put in dwarf plants it makes the stem grow considerably. In many cases the gibberellins are able to overcome the genetic limitations of dwarf plants.
