In addition to standard manipulations aimed at obtaining a rich harvest, sometimes there is a need to resort to auxiliary means stimulating the growth of vegetables and fruits. These include gibberellin.
General information
Gibberellin represents a growth hormonederived from the parasitic fungus of the genus Fusarium. They are treated with seeds before sowing in order to increase crop volumes. Used to improve the taste and visual qualities of fruits such as grapes, tomatoes. With the use of gibberellin, work is being done to obtain sterile berries without seed.
Important! Use the drug only in productive years. If you use the funds in the period of crop failure, then instead of large fruits you get small substandard berries.
The drug can be produced both in liquid and in powder state. 
It is necessary to dissolve the agent in alcoholic solutions, since crystals in water are not capable of fully displaying properties. To get lush bunches of grapes with large berries, use gibberelin patch. In most cases, gibberellin treatment is carried out by spraying, but sometimes a method of dipping grapes in solution is used.
Properties and mechanism of action
Most common purpose of the solution - acceleration of seed germination. Thanks to the active active substance, metabolic processes in the germinal roots are accelerated, which contributes to rapid growth.
Under the action of the drug cells stretch and divide, with the result that the shoot rapidly grows in height. The tool can be used for forced flowering of plants in the absence of suitable conditions for this.
At the time when seed germination occurs, gibberellin interacts with other plant-derived hormones - auxins.
Their combined effect leads to parthenocarpy bunches, as a result of which the fetus can grow without fertilization. This property of the drug is used for growing grapes without stones. 
Instructions for use of growth regulator
Before you start using gibberellin, you must carefully study the instructions.
When to use the drug
Depending on the group of cultures, as well as the desired result, the period of application of the solution varies. There is no definite recommendation when it is best to process plants. It is necessary to get acquainted with the detailed instruction, where it will be indicated which crops, when and how to process.
Popular stimulants and plant growth regulators for your garden: “Charm”, “Kornerost”, “Etamon”, “NV-101”, “Chunky”, “Prophet”, “Energen”, “Vympel”.
Phytohormone application method
There are several ways to use the drug:
- spraying inflorescence - has the lowest efficiency, as it depends on the weather;
- dipping the inflorescence - requires a lot of solution, but gives a good effect;
- application of the drug to the comba is an ideal method for processing grapes;
- the contact method is very laborious, it is recommended to use only professionals.
It depends on what cultures you plan to process, when and how to do it. Consider an example of how to use the phytohormone.Did you know? Gibberellic acid allows you to increase the yield of grapes up to 230%.
To prepare the working fluid, it is necessary to dissolve the gibberellin powder in alcohol, then add water to obtain a solution of the desired concentration.
Vineyards. As a rule, the drug is used to accelerate the germination of seed, in order to increase the size of the berries and increase the overall yield. The first time you need to spray the vine during the first flowering period, the second time - after 7 days. 10 days after the flowering of the vines ends, a gibberellin patch should be placed close to the brush. When preparing the solution, consider the flow rate of 0.002 g / sq. m. For the entire season, it is recommended to carry out 2-3 treatments. Citrus. Thanks to the drug, the amount of the crop rises, fruiting is stabilized, and the fruit properties are improved. It is necessary to process the plant before the buds appear, or during the period when the fruit will have a green color. Consumption per 1 square. m is 0.003 g. It is recommended to carry out processing 1-2 times per season.
Vegetable crops. The tool promotes the formation of ovaries and prevents them from falling off, increases yield. Tomato saplings must be processed before planting in open ground for 10 days. Consumption per 1 square. m is 0.0006-0.004 g. The recommended number of treatments per season is 1.
Most often, gibberellin is used to process grapes, its use helps to obtain large and beautiful berries.
Important! It is not necessary to isolate from seed pollination clusters of seeds that are treated with the drug - this will lead to their drying out.
Compatibility of gibberellin solution
The drug can be used with other plant hormones. With gibberellins, brassinosteroids can be combined to process leaves. If you are engaged in the summer germination of potato tubers, we recommend using a mixture of gibberellin and thiourea: 2 mg / l + 20 mg / l.
Advantages of growth regulator
Gibberellin, widely used for processing grapes and other crops, has a mass merits. Among them:
- increase seed growth rate;
- stimulation of shoot growth;
- activation of photosynthetic processes that contribute to the growth of the vegetative mass;
- increase in the volume of grapes, as well as the size of other fruits and berries;
- application for growing seedless fruits;
- extension of the growing season;
- contributes to the elongation of floral arrows and increase the size of the buds.
Did you know? When processing wine and brandy grapes the fruit will have a sour taste. For the preparation of alcoholic beverages, it is better to use naturally grown berries.
Gibberellin solution is not dangerous for animals, people, does not cause a toxic reaction. 
Preparations based on gibberellic acid
TO gibberellin group drugs include:
- "Ovary";
- "Bud";
- "Gibbersib".
The active ingredient gibberellin inhibits the growth of the root system, and auxin, on the contrary, stimulates the growth of roots and inhibits the growth of shoots. The result is that they interact with each other and contribute to the harmonious growth of the plant.
Preparations based on gibberellic acid make it possible to achieve a large and high-quality harvest, which is the goal of all summer residents and farmers.
