Key Applications & Uses

Seed Germination & Dormancy Breaking: Promotes rapid and uniform germination of seeds, particularly those with hard coats or requiring stratification (e.g., tree seeds, certain cereals).

Stem & Cell Elongation: Stimulates internode elongation in crops like grapes (for longer rachises), sugarcane, and ornamentals, leading to improved growth and harvestability.

Fruit Setting & Development: Enhances fruit set in conditions unfavorable for pollination (e.g., in tomatoes, cherries). Can be used to increase berry size in grapes and promote parthenocarpic (seedless) fruit development.

Flowering Induction: Can modify flowering time and sex expression in some plant species (e.g., induce flowering in long-day plants under short-day conditions).

Malting in Brewing: Accelerates and synchronizes the malting process in barley for the brewing industry.

Plant Tissue Culture: Used in media formulations to stimulate callus growth, organogenesis, and embryo development.

 

Storage & Handling Information

Storage Conditions: Store in a cool, dry, and dark place. For long-term stability, store at 2-8°C (refrigerated) under an inert atmosphere.
