GIBKUL

Biological activity of gibberellins in "Gibkul"

"Gibkul" is based on an active ingredient from the gibberellin group—phytohormones that play a vital role in the physiological processes of fruit crops. Unlike synthetic stimulants that work by exhausting the plant, this growth regulator influences cellular metabolism by stimulating division and elongation, which is critical during the fruit-set period.

Technical analysis of the mechanism of action

• Protein synthesis and enzymatic activity: Gibberellins activate the expression of genes responsible for synthesizing enzymes that break down starch into sugars. This ensures rapid fruit weight gain and improved organoleptic properties.
• Hormonal balance: The preparation works effectively on apple and pear trees, mitigating the effects of temperature stress, which often causes ovary drop.
• Nutrient translocation: The application of "Gibkul" redirects the flow of assimilates from vegetative organs to reproductive ones, accelerating ripening and normalizing fruit sizing within the canopy.

Practical application details

This product from Vast Agrochemical International Limited (China) requires strict adherence to usage protocols. Due to its Class 3 hazard rating, the preparation is relatively safe when protective measures are followed; however, its efficacy directly depends on the quality of surface coverage. The foliar spraying method ensures uniform penetration of the active substance through the leaf cuticle. Using "Gibkul" is a precise tool for intensification in orcharding, allowing growers not only to shorten ripening cycles but also to enhance the marketability of apples and pears for future distribution.
