Description

Gibberellic Acid (GA3) is a key plant growth hormone belonging to the diterpenoid class of gibberellins. It is essential for stimulating cell division and elongation, directly influencing processes like seed germination, stem growth, and fruit development. This makes it a critical input for agricultural, horticultural, and research sectors seeking to enhance crop yield, manage flowering times, and improve fruit set. Its targeted action provides a powerful tool for optimizing plant physiology and overcoming growth limitations.

Application

• Seed Germination & Dormancy Breaking: Promotes uniform and rapid germination of seeds, particularly for those with hard coats or requiring stratification.
• Fruit Setting & Development: Applied to induce parthenocarpy (seedless fruit development) and improve fruit size, shape, and quality in crops like grapes, citrus, and tomatoes.
• Stem Elongation & Bolting: Used to stimulate stem growth in rosette plants and to induce bolting in biennial crops for seed production.
• Malting in Brewing: Accelerates and standardizes the malting process in barley for the brewing industry by promoting uniform germination.
• Flowering Induction: Helps regulate and synchronize flowering times in certain long-day plants and under non-inductive conditions.
• Plant Tissue Culture: A vital component in growth media to stimulate callus growth and shoot elongation in micropropagation protocols.
• Crop Yield Enhancement: Applied to increase cane length in sugarcane and to improve overall biomass and harvest index in various crops.
• Research & Biochemical Studies: Serves as a standard and active ingredient in plant physiology, biochemistry, and agrochemical research.

Quality Control

Our Gibberellic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for agricultural and research applications. A Certificate of Analysis (COA) detailing purity, identity, and specific impurities is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent degradation due to moisture absorption.
