Factory Supply Ga3 10% Tablet 90% TC Gibberellic Acid Application of GA3 in Crops
Gibberellic Acid GA3, Acid Gibberellic (also called Gibberellin A3, GA, and GA3) is a hormone found in plants and fungi. Its chemical formula is C19H22O6. When purified, it is a white to pale-yellow solid.
Plants in their normal state produce low amounts of GA3. It is possible to produce the hormone industrially 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 GA3, Acid Gibberellic 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 it[citation needed. GA stimulates the cells of germinating seeds to produce mRNA molecules that code for hydrolytic enzymes.
Gibberellic Acid GA3, Acid Gibberellic 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.
Function:
1. Gibberellic Acid GA3, Acid Gibberellic can stimulate plant stem elongation by stimulating cell division and elongation.
2. And 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.
3. Then, it has been proved from production practice for many years that the application of gibberellins has signification effect in raising the yield of rice, wheat, corn, vegetable, fruit, etc.
When used for hybrid rice seed growing, gibberellic acid can adjust blossoming period and promote the spike growing of the parents. This will in turn increase the valid spike counts and grain counts with obviously increased burliness rate.
| PLANT | DOSAGE(PPM) | APPLICATION | EFFECT |
| lettuce | 10-25 | spraying 2-3 times when it has 13-14 leafs | increase production |
| celery | 20 |
spraying 2 times to all parts of the plant during 15-30 days before harvest
|
make the plant higher, increase the amount of leaf |
| spinage | 10-20 | spraying to the face of leafs when it has 5-6 true leafs | make the leaf bigger, obviously increase production |
| ax vegetable | 10-20 | spraying to the face of leafs about 10 days before harvest | accelerate growth of the plant, bigger the leafs, increase production |
| tomato | 50 | drop at the tail of flowers when the plant has 70% flower | few shatter, more fructification, early ripeness |
| cucumber | 50 | spraying to young cuke when young cuke grow to 3 inchs | bigger the fruit, early reapness |
| leek | 10-30 | spraying 3-5 times during 2-3 days after reap | elongate and bigger the area of the leafs, increasse production |
| cabbage | 10-20 | spraying to the face of leafs at 10 days before harvest | accelerate growth of the plant, bigger the area of the leafs, increase production |
| capsicum | 10-20 | spraying to the flower at the beginning of florescence to blooming | increase production |
| Chinese watermelon | 20-30 | spraying to little melon, once time every 6 days, total 2-3 times | accelerate growth and increase production |
| kidney bean | 30-40 | spraying to the flower at florescence | increase production |
