Description

cis-Zeatin Riboside (Czr) is a highly active cytokinin derivative, a key plant growth regulator essential for cell division and differentiation. Its value lies in its superior stability and bioactivity compared to its base compound, making it a critical component for advanced plant tissue culture and agricultural biotechnology research. This product is primarily needed by manufacturers of plant growth media, agrochemical research & development laboratories, and academic institutions focused on plant physiology and genetic engineering.

Application

• Plant Tissue Culture Media: A critical additive for inducing shoot proliferation, callus growth, and organogenesis in a wide range of plant species.
• Agricultural Biotechnology Research: Used in studies on plant senescence delay, nutrient mobilization, and stress response mechanisms.
• Seed Germination & Vigor Enhancement: Applied to improve germination rates and promote stronger seedling establishment in high-value crops.
• Micropropagation Protocols: Essential for the commercial clonal propagation of ornamental plants, fruit trees, and forestry species.
• Plant Hormone Studies: Serves as a standard reference compound in biochemical and molecular biology research on cytokinin signaling pathways.
• Formulation of Specialty Plant Growth Regulators (PGRs): Used as an active ingredient in the development of next-generation biostimulants and PGR blends.
