Gibberellin A4
Application Notes
Gibberellin A4 is a C19-gibberellin produced by higher plants and the rice pathogenic fungus Gibberella fujikori. Gibberellin A4 is the dehydroxy analogy of gibberellin A3. The gibberellins have long been known as plant growth regulators. Gibberellins can stimulate rapid stem and root growth, induce mitotic division in the leaves of some plants, and increase seed germination rates.
