Gibberellic acid Usage And Synthesis
  • DescriptionGibberellic 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.

  • UsesGibberellic 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.
  • DefinitionChEBI: A C19-gibberellin that is a pentacyclic diterpenoid responsible for promoting growth and elongation of cells in plants.
  • General DescriptionWhite powder.
  • Air & Water ReactionsSlightly water soluble .
  • Reactivity ProfileGibberellic acid is readily degraded by acids. .
  • Fire HazardFlash point data for Gibberellic acid are not available. Gibberellic acid is probably combustible.
  • Agricultural UsesPlant 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 UsesGibberellic acid is an organic acid used as a plant growth hormone. It is formed by the fungus Gibberellafujikuroi in aerated submerged culture.
  • Agricultural UsesGibberellin 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.
