General description
Gibberellic acid is an endogenous plant growth regulator
Application
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.
Gibberellin A3 (G1025, G7645) and A4 (G7276) may be used as supplements to plant growth media such as Murashige and Skoog media. The specific actions of A3 and A4 or combinations of Gebberellins should be determined in specific plant applications.
Biochem/physiol Actions
Phytohormone that controls important aspects of plant growth: germination, elongation, and flowering. The effects are mediated by inducing degradation of the DELLA repressor protein, and probably other minor signalling pathways.1
