Best Price Plant Growth Regulator Ga3 Gibberellic Acid 90%TC

Gibberellic acid belongs to a natural plant hormone.It is a Plant Growth Regulator which may cause a variety of effects, such as the stimulation of seed germination in some cases. GA-3 naturally occurs in the seeds of many species. Presoaking seeds in GA-3 solution will cause the rapid germination of many types of highly dormant seeds, otherwise it would need cold treatment, after-ripening, aging, or other prolonged pre-treatments.Gibberellins are used in agriculture for various purposes. It is sprayed on seedless grapes to increase grape size and yield, and is used on navel oranges, lemons, blueberries, sweet and tart cherries, artichokes and other crops to decrease or increase fruit set, delay rind aging, etc. These effects are highly dependent on concentration and stage of plant growth.

Application

1. It can increase the yield of three-line hybrid rice seed production: this is a major breakthrough in hybrid rice seed production in recent years and an important technical measure.

2. It can promote seed germination. Gibberellic acid can effectively break the dormancy of seeds and tubers, promoting germination.

3. It can accelerate growth and increase yield. GA3 can effectively promote plant stem growth and increase leaf area, thereby increasing yield.

4. It can promote flowering. Gibberellic acid GA3 can replace the low temperature or light conditions required for flowering.

5. It can increase fruit yield. Spraying 10 to 30ppm GA3 during the young fruit stage on grapes, apples, pears, dates, etc. can increase the fruit setting rate.

Attentions

1. The pure gibberellic acid has low water solubility, and the 85% crystalline powder is dissolved in a small amount of alcohol (or highly alcoholic) before use, and then diluted with water to the desired concentration.

2. Gibberellic acid is prone to decomposition when exposed to alkali and is not easily decomposed in a dry state. Its aqueous solution is prone to damage and failure at temperatures above 5 ℃.

3. Cotton and other crops treated with gibberellic acid have an increase in infertile seeds, so it is not suitable to apply pesticides in the field.

4. After storage, this product should be placed in a low temperature, dry place, and special attention should be paid to preventing high temperatures.
