Function Description Gibberellic Acid/GA3/Gibberellin A3 belong to a natural plant hormone. 

 

It can stimulate plant stem elongation by stimulating cell division and elongation. 

 

It can break seed dormancy, promote germination, and increase fruit setting rate,  or cause parthenocarpic (seedless) fruit by stimulating stems of a plant higher and leaves bigger. 

 

Then, it has been proved from production practice for many years that the application of gibberellins has significant effect on raising the yield of rice, wheat, corn, vegetable, fruit, etc.
Applications Reduce the fruit falling off.

 

To prolong the shelf life and keep fresh of fruits.

 

To promote growth of the vegetative  plants.

 

To promote spouting of seed and breaking dormancy.

 

To promote fruit set and the formation of seedless fruits.

Description:
Gibberellic acid (also called Gibberellin A3, GA, and GA3) is a hormone found in plants and fungi. Gibberellic acid chemical formula is C19H22O6. When purified, Gibberellic acid is a white to pale-yellow solid. Gibberellic acid is a kind of efficient plant growth regulator, promote crop growth, early mature, improve quality and increase production.
Gibberellic acid can be used for rice, wheat and barley, cotton, fruit, vegetables and other crops, promote its growth, sprout, blossom and bear fruit.
Plants in their normal state produce low amounts of GA3. It is possible to produce the hormone industrially by using microorganisms. Nowadays, it is produced by submerse fermentation, but this process presented low yield with high production costs and hence higher sale value. One alternative process to reduce costs of the GA3 production is Solid-State Fermentation (SSF) that allows the use of agro-industrial residues.
Gibberellic acid is a simple gibberellin, a pentacyclic diterpene acid promoting growth and elongation of cells. It affects decomposition of plants and helps plants grow if used in small amounts, but eventually plants develop tolerance to needed. GA stimulates the cells of germinating seeds to produce mRNA molecules that code for hydrolytic enzymes.
Gibberellic acid is a very potent hormone whose natural occurrence in plants controls their development. Since GA 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 and 10 mg/L.
