Uses

Gibberellic acid has the main following uses:

1.Gibberellic acid is a very potent hormone whose natural occurrence in plants controls their development. Since Gibberellic acid regulates growth, applications of very low concentrations can have a profound effect while too much will have the opposite effect. It is usually used in concentrations between 0.01-10 mg/L.
2.Gibberellic acid is a simple gibberellin, promoting growth and elongation of cells.

3.Gibberellic acid is sometimes used in laboratory and greenhouse settings to trigger germination in seeds that would otherwise remain dormant. It is also widely used in the grape-growing industry as a hormone to induce the production of larger bundles and bigger grapes, especially Thompson seedless grapes, and in the Okanagan and Creston Valley it is used in the cherry industry as a growth regulator.
