How does gibberellin actually work
WebGibberellins are a group of hormones that help plants grow by stimulating cell division and elongation in the stem. Dwarf plant varieties have been shown to have very low levels of gibberellins. This is often due to a mutation in a gene involved in the synthesis of gibberellins. Under experimental conditions, treating these dwarf varieties with ... WebGibberellin (GA) is a plant hormone regulating key processes in plants; many of them are of Gibberellins (GAs) are a class of tetracyclic diterpenoid phytohormones that regulate many aspects of plant development, including seed germination, stem elongation, leaf expansion, pollen maturation, and the development of flowers, fruits and seeds.

Gibberellins play an important role in several developmental stages in plants, but their claim to fame is making stems longer. Gibberellins promote stem elongation between nodes on the stem.
WebGibberellic acid is a plant hormone that helps with the germination of seeds, the growth of stems and leaves, and the development of flowers. It occurs naturally in gibberellin, which is produced by fungi in the genus Gibberella.
