gibberellin

one of a range of growth regulators in plants that stimulate stem elongation but, unlike AUXINS, do not inhibit root growth. Gibberellins can be used to induce BOLTING in immature plants and to remove dwarfness in mature plants. Unlike auxins, gibberellins can move freely around the plant. Compare ANTIGIBBERELLIN.
