Description

3,24-Diepibrassinolide is a highly active, naturally occurring brassinosteroid plant growth regulator. This compound is valued for its potent ability to enhance crop stress tolerance, promote growth, and improve yield and quality at very low application rates. It is an essential tool for agricultural researchers, formulators, and producers seeking advanced plant biostimulant solutions for high-value crops in challenging environments.

Application

• Plant Growth Regulation: Used to stimulate cell division and elongation, promoting overall plant vigor, root development, and biomass accumulation.
• Stress Resistance Enhancement: Applied to improve crop tolerance to abiotic stresses such as drought, salinity, high temperatures, and chilling injury.
• Yield and Quality Improvement: Employed in fruit, vegetable, and cereal cultivation to increase fruit set, size, uniformity, and nutritional content.
• Seed Treatment: Used as a seed soak or coating to improve germination rates, seedling vigor, and early root establishment.
• Agricultural Formulations: Serves as a key active ingredient in the development of advanced foliar sprays, soluble concentrates, and other plant growth regulator products.
• Plant Physiology Research: A critical standard and reagent for studying brassinosteroid signaling pathways, hormone interactions, and plant developmental biology.
