Benefits & Application of Gibberellin Acid

Gibberellic Acid Uses in Agriculture

  1. Promotes greater photosynthesis and plant metabolism.
  2. Larger leaves and larger roots.
  3. Increases cell growth in stems, leaves, and roots.
  4. Used to produce long, slender stems in plants grown in standard and semi-standard horticultural crops.
  5. Increase the stem length of some flower crops engaged in the flower trade.
    Improve the growth of young plants produced from cuttings, seeds, or flower stalks.
  6. Used to help plants suffering from nutrient and growth deficiencies.
  7. Improve crop resistance under environmental stresses such as low temperature, high salinity, drought and hypertonicity.
  8. Promote seed germination and break dormancy.

Use Cautions

  1. Because of the low solubility of gibberellin (GA3) in water, dissolve gibberellin (GA3) in a small amount of ethanol and then add water to reach the desired concentration.
  2. Use with alkaline substances must be avoided; it may be used with neutral or weakly acidic substances.
  3. Gibberellin (GA3) must be stored under low temperature and dry conditions. It should be used immediately after the addition of water.
  4. Gibberellin can produce good results only when water and fertilizer are supplied adequately and cannot replace fertilizer.
  5. The prepared (dissolved) gibberellin solution should not be left for too long, so as not to affect the efficacy.
  6. Gibberellic acid should not be heated, once the temperature exceeds 60 degrees, it will lose its effectiveness.
  7. Gibberellin has a strong physiological activity, and its use concentration is generally low, so you must strictly control the concentration and the amount of liquid when using it.

Seeds of lettuce, tobacco and begonia require light conditions for germination and are called light-demanding seeds.
When these light-demanding seeds are treated with gibberellin, they can also germinate in dark conditions. On the contrary, seeds that germinate in dark conditions germinate easily in light conditions after gibberellin application.

For example, ginseng is soaked in 20ppm gibberellic acid for 15 minutes, the seedlings can emerge 2 days earlier, and the germination rate is also significantly increased.

Gibberellin hormone has a certain effect on the release of dormancy. The main mechanism is that gibberellin can hinder the degradation of intercellular dormancy and release signal transduction of plasmodesmal callose, so that the signal substance can be transported to the apical meristem. Organize, thereby lifting dormancy.
