Gibberellin A4 is a plant growth hormone that regulates growth and differentiation of plant cells for elongation, germination and enzyme induction.
Biochem/physiol Actions
Gibberillic acids (GA) are important plant growth hormones that promote plant cell growth and elongation. Gebberillins promote rapid stem and root growth, induce mitotic division and initiate (break dormancy) and increase seed germination rates. The gibberellins are also involved in processes such as gravitropism, tensioning and floral display.
