"WebGibberellins are a group of hormones that help plants grow by stimulating cell division and elongation in the stem. This is often due to a mutation in a gene involved in the synthesis of gibberellins. Under experimental conditions, treating these dwarf varieties with gibberellins results in them growing to the same height as normal varieties. " - Dimple tray biology
