Thermo Scientific™ Gibberellic Acid (GA₃) is a highly purified plant hormone (≥90%) widely used in plant tissue culture, greenhouse propagation, and agricultural research. It functions as a potent growth regulator that stimulates cell elongation, germination, flowering, and root development, mimicking natural gibberellins found in plants.
GA₃ is often employed to break seed dormancy, accelerate stem elongation, and enhance reproductive development, making it an essential tool in both basic plant science and commercial plant production. It is compatible with Murashige and Skoog (MS) media and other basal media formulations.
Key Features
- ≥90% purity by HPLC and titration
- Promotes stem elongation, root and shoot growth, seed germination, and floral development
- Breaks dormancy in seeds and buds
- Soluble in water and ethanol
- Supplied as a white to cream to pale brown powder
- Suitable for supplementation into plant tissue culture media
- Backed by Thermo Scientific quality and documentation
Applications
- Plant tissue culture (e.g., shoot proliferation, somatic embryogenesis)
- Seed germination enhancement in research and horticulture
- Breaking bud dormancy in grapevines, pome fruits, and ornamentals
- Crop development studies in cereals and horticultural plants
- Supplementation into MS media or custom growth media
