Description

Homocastasterone is a plant growth regulator belonging to the brassinosteroid class of phytohormones, known for its potent biological activity. This compound is crucial for enhancing crop resilience, promoting growth, and improving yield quality under various environmental conditions. It is primarily utilized by agricultural researchers, agrochemical formulators, and advanced horticultural operations seeking to develop next-generation plant biostimulants and growth-enhancing products.

Application

• Agricultural Research & Development: Used as a key reference standard and active ingredient in studies exploring brassinosteroid signaling, plant stress tolerance, and growth regulation.
• Agrochemical Formulations: Incorporated into foliar sprays, seed treatments, and other specialty formulations designed to improve crop vigor, photosynthesis, and resistance to abiotic stresses like drought and salinity.
• Horticulture & Floriculture: Applied to enhance the quality, size, and shelf-life of fruits, vegetables, and ornamental plants in controlled environment agriculture.
• Plant Tissue Culture: Serves as a media supplement to promote cell division, elongation, and differentiation in vitro for micropropagation and genetic engineering applications.
• Seed Technology: Used in seed priming treatments to improve germination rates, seedling establishment, and early root development.
