Description and Uses
Gibberellic acid (GA) is a tetracyclic di-terpenoid compound. It is one of the major hormones that can be synthesized in plants and fungi. It has various kinds of physiological effects including stimulating seed germination, inducing mitotic division of the leaves, triggering transitions from meristem to shoot growth, vegetative to flowering, determining sex expression and grain development through crosstalk with many environmental signals such as light, temperature and water. In lab and greenhouse, it can be used to trigger germination of seeds which has previously remained dormant. It can also used to induce the production of larger amount and bigger grapes, boosting the grape industry. In industry, GA can be produced from Solid-state Fermentation (SSF) which can have relatively high yield.
Gibberellic Acid is a a pentacyclic diterpene acid. Gibberellic Acid is a hormone that is found in plants which promotes the growth and elongation of cells. Gibberellic acid acts as a plant growth reg ulator on account of its physiological and morphological effects in extremely low concentrations. Generally Gibberellic acid affects only the plant parts above the soil surface.
