The Uses of GIBBERELLIC ACID POTASSIUM SALT

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.
