Chemical Properties
White crystalline powder, odorless. Del-
iquescent, sol in water, alc, acetone. A salt of gib-
berellic acid.
Uses
Promote and control development of malt in
grain.
Uses
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
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. Auxins influence the biosynthesis and signaling of GA. GA is involved in auxin-mediated primary root elongation by modulating auxin signaling and transport.
Safety Profile
When heated to
decomposition it emits acrid smoke and
irritating fumes.
