Factory Supply Ga3 20% 10% Tablet Berelex Gibberellic Acid Plant Growth Regulator
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 it. GA stimulates the cells of germinating seeds to produce mRNA molecules that code for hydrolytic enzymes.
Specification:
•Break seed dormancy
•Promote germination
•Increase fruit setting rate

Properties:
Gibberellic acid is a widely-used plant growth regulator, and it is one of the five main plant hormones. The product is primarily used to promote the fruition of the melons and fruit plants such as pineapple, orange and grape, and to promote the formation of Seedless fruits. Its melting point is 223-225°C. It easily dissolve in ethanol, acetone. Slightly dissolve in water (5g/L) or chloroform. GA3 is high stable in acidic solution or litmusless solution. Rapidly break down in alkali solution. Rapidly decomposed by heat.
Benefits
It is used to stimulate the nourishment growth in leafy vegetables like spinach.
It is able to break the dormancy of seeds such as potato and ginseng, and promote seed development. Gibberlin also helps to defer the decrepitude of fruits and therefore to prolong the freshness.
It is able to change the proportion of female and male flowers, and blossoming time also.
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 |
Applications
Mode of action Acts as a plant growth regulator on account of its physiological and morphological effects in extremely low concentrations. Translocated. Generally affects only the plant parts above the soil surface. Uses Has a variety of applications, e.g. to improve fruit setting of clementines and pears (especially William pears); to loosen and elongate clusters and increase berry size in grapes; to control fruit maturity by delaying development of the yellow colour in lemons; to reduce rind stain and retard rind ageing in navel oranges; to counteract the effects of cherry yellows virus diseases in sour cherries; to produce uniform seedling growth in rice; to promote elongation of winter celery crop; to induce uniform bolting and increase seed production in lettuce for seed; to break dormancy and stimulate sprouting in seed potatoes; to extend the picking season by hastening maturity in artichokes; to increase the yield in forced rhubarb; to increase the malting quality of barley; to produce brighter-coloured, firmer fruit, and to increase the size of sweet cherries; to increase yields and aid harvesting of hops; to reduce internal browning and increase yields of Italian prunes; to increase fruit set and yields of tangelos and tangerines; to improve fruit setting in blueberries; to advance flowering and increase the yield of strawberries; and also a variety of applications on ornamentals. Application rates up to 80 g/a per application, depending on desired effect.
