It is a plant growth regulating hormone that promotes plant cell growth and elongation. They promote rapid stem and root growth, induce mitotic division and initiate (break dormancy) and increase seed germination rates. They 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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
