Manufacturer Supply Water Soluble Plant Growth Regulator 90%TC 20% 10% Tablet Gibberellic Acid GA3
Gibberellic acid GA3 is found naturally in virtually all plant species. It is a highly effective plant hormone, increasing size and quality of fruits, vegetables, and other crops, essential for optimum growth and development. Gibberellic acid GA3 also plays a role in the regulation of other plant processes such as flowering, seed germination, dormancy, and senescence. Gibberellic acid GA3 is used in vegetables, fruits and other crops to improve crop quality and value.

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 |
Main Application:
1. Gibberellic acid is used on agriculture:
2. GA3 can promote the cucumber and watermelon open more female flowers.
3. Promote potatoes, peas and lentils sprout by breaking dormancy.
4. Promote the celery, spinach and leaf lettuce leaves hypertrophy.
5. Increase the fruit setting ratio of the cucumber, eggplant and tomato.
6. Delay senescence and keep fresh of fruits.
Function:
1.Gibberellic acid 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.
2.Gibberellic acid has 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.
3.Gibberellic acid 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.
4.Gibberellic acid used 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.
