Product Detail

Gibberellic Acid GA3 is a broad-spectrum plant growth regulator that can promote the growth and development of crops, make them mature earlier, increase yield and improve quality; it can quickly break the dormancy of organs such as seeds, tubers and bulbs, and promote germination; it can reduce the shedding of buds, flowers, bolls and fruits, increase the fruit-bearing rate or form seedless fruits.

The pure product is white crystals, and the industrial product is white powder. It is soluble in organic solvents such as alcohols, ketones, and esters, but hardly soluble in ether, chloroform, benzene, and water.

It forms salts with potassium and sodium ions and dissolves in water. Gibberellic acid solids are relatively stable. It will not become ineffective if stored for a long time under dry and airtight conditions, but its aqueous solution is unstable. I

Functions

1. Promote growth, early maturity, and increase production
2. Break dormancy and promote germination
3. Promote fruit growth
4. Extend storage period
5. Change the ratio of male and female flowers and increase seed yield
6. Promote stemming and flowering, and increase the breeding coefficient of improved varieties
7. Eliminate the damage caused by other hormones

How to use

Use alone: Spraying concentration 5 ~ 50mg/L; Spraying or fruit dipping treatment 50 ~ 200mg / L.

Mixed use: Mixed with auxin and cytokinin, which can promote fruit setting, fruit expansion, increase yield, and improve quality.

Gibberellic acid can be sprayed, applied to seeds, and dipped in roots.

Gibberellic acid can work better when used in conjunction with other regulators and nutrients.

Characteristics

-Endogenous hormones commonly found in plants are broad-spectrum plant growth regulators. The most prominent effect of gibberellins is to accelerate cell elongation (gibberellins can increase the content of auxin in plants, and auxin directly regulates cell elongation). It also promotes cell division and can promote cell expansion (but does not cause acidification of cell walls).
-Low water solubility, should be dissolved with a small amount of alcohol or white wine first, then diluted with water
-The number of sterile seeds of crops treated with gibberellic acid increases, so it is not suitable to apply pesticides in seed fields
-The best time to spray is before 10:00 am and after 3:00 pm. If it rains within 4 hours after spraying, spray again
-The number of sterile seeds of crops treated with gibberellic acid increases, so it is not advisable to apply pesticides in seed fields
