| | Gibberellic acid Usage And Synthesis |
| Description | 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.
| | Chemical Properties | white powder | | Uses | 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. | | Uses | Gibberellic acid is used as a plant growth hormone. It is also used to trigger germination in dormant seeds in laboratory and green house settings and to stimulate rapid stem and root growth and induce mitotic division in the leaves of some plants. It also serves in grape growing industry as a hormone to induce the production of larger bundles and bigger grape. | | Definition | ChEBI: A C19-gibberellin that is a pentacyclic diterpenoid responsible for promoting growth and elongation of cells in plants. | | General Description | White powder. | | Air & Water Reactions | Slightly water soluble . | | Reactivity Profile | Gibberellic acid is readily degraded by acids. . | | Fire Hazard | Flash point data for Gibberellic acid are not available. Gibberellic acid is probably combustible. | | Agricultural Uses | Plant growth hormone, Plant regulator: Gibberellic acids (Gibberellins) are naturally occurring plant hormones that are used as plant growth
regulators to stimulate both cell division and elongation
that affects leaves and stems. Applications of this hormone also hastens plant maturation and seed germination.
Delayed harvesting of fruits, allowing them to grow larger.
Gibberellic acids are applied to growing field crops, small
fruits, grapes, vines and tree fruit, and ornamentals, shrubs
and vines. | | Agricultural Uses | Gibberellic acid is an organic acid used as a plant growth hormone. It is formed by the fungus Gibberellafujikuroi in aerated submerged culture. | | Agricultural Uses | Gibberellin is a growth promoting substance found widely in plants. It was first isolated from the fungus Gibberella. Gibberellin increases the rate of photosynthesis and helps in the elongation of cells. It promotes the flowering and germination of plants. With a general formula of Cl9H22O6, gibberellins are also produced by Azotobacter, Azospirillum, etc. | | Trade name | ACTIVOL®; BERELEX®; BRELLIN®;

The effects are mediated by inducing degradation of the DELLA repressor protein, and probably other minor signalling pathways. | | Safety Profile | Mildly toxic by
ingestion. Questionable carcinogen with
experimental tumorigenic data. hlutation
data reported. When heated to
decomposition it emits acrid smoke and
irritating fumes. | | Purification Methods | It crystallises from EtOAc, EtOAc/pet ether, MeOH/pet ether or Me2CO/pet ether. [Cross J Chem Soc 3022 1960, Beilstein 18 III/IV 6533.] | | References | https://en.wikipedia.org/wiki/Gibberellic_acid
