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.
GA可加强IAA对养分的动员效应，促进某些植物坐果和单性结实、延缓叶片衰老等。此外，GA也可促进细胞的分裂和分化，GA促进细胞分裂是由于缩短了G1期和S期。但GA对不定根的形成却起抑制作用，这与生长素又有所不同。
