Plant Growth Regulator Gibberellin Gibberellic Acid Ga3 Ga4 AG7 90%Tc 10%Tb 20%Sp

Gibberellic Acid is important hormones that naturally exist in plants. They significantly promote plant growth and development. Gibberellic Acid is synthesized in various parts of the plant, including seeds, young shoots, leaves, flowers, fruits, and roots. It produced in the roots move upward, while those generated in the apex move downward. Its transport mainly occurs in the phloem. The speed of it transport is similar to that of photosynthetic products.

Artificially synthesized Gibberellic Acid is absorbed mainly through the leaves, tender shoots, flowers, seeds, or fruits. They then transfer to their target sites.

This regulator has a wide range of physiological functions. It stimulates cell growth and elongates stems. In some plants, it promotes bolting and increases leaf area. It accelerates the growth of young branches and encourages parthenocarpy and fruit growth. Gibberellic Acid break seed dormancy and influence flower sex ratios. They control flowering time and reduce flower and fruit drop. Gibberellic Acid promote the accumulation of metabolites in the phloem and activate the cambium. Additionally, they inhibit plant aging and maturation processes. They prevent lateral bud dormancy and tuber formation.
 

Features of Gibberellic Acid

Taking grapes as an example, spraying gibberellins can promote fruit enlargement, encourage seedlessness, and increase yield. However, there are various methods of application. For instance, before flowering, a solution of 4-6 milliliters per liter of gibberellins can be sprayed on the flower clusters. After flower drop, a solution of 10-20 milliliters per liter can be applied to young fruits. The concentration varies depending on the growth stage, but the goal is to address fruit-related issues.

2. Promote Nutritional Growth of Crops

Using grapes as an example again, Gibberellic Acid is particularly effective during the seedling stage. The key is the concentration. During the grape seedling stage, a solution of 50-100 milliliters per liter of Gibberellic Acid can be sprayed to promote rapid growth of grape seedlings. This process generally requires two applications, spaced about 10 days apart, and the growth-promoting effect is very noticeable.

3. Enhance Germination Rate of Crops

This mainly applies to cereal crops, such as wheat. Soaking seeds in Gibberellic Acid can enhance their germination rate. Typically, a solution of 5-10 milliliters per liter of Gibberellic Acid is used to soak the seeds for about 8 hours. After soaking, the seeds should be air-dried naturally before planting.

4. Preservation Effect

For example, spraying Gibberellic Acid solution on cucumbers after harvest has a preservation effect. The key is to control the concentration. A solution of 10-50 milliliters per liter of Gibberellic Acid can extend the preservation period effectively.

5. Regulate Flowering

Gibberellic Acid can be used to regulate flowering, particularly to increase the number of female flowers, which leads to a higher fruit set. The timing and concentration of the spray are crucial. Generally, it should be applied during the first leaf stage, using a concentration of 50-100 milliliters per liter of Gibberellic Acid. A single application is sufficient.
