Description

trans-Zeatin Riboside is a highly active cytokinin plant growth regulator, a nucleoside derivative of the natural hormone zeatin. Its core value lies in its superior stability and bioactivity compared to its free base form, making it a critical component for precise plant tissue culture and developmental research. This compound is essential for professionals in agricultural biotechnology, plant physiology research, and the production of high-value horticultural crops who require reliable, high-purity biochemicals to stimulate cell division, delay senescence, and promote bud formation.

Application

• Plant Tissue Culture Media: A key additive for inducing shoot proliferation, callus growth, and micropropagation of orchids, medicinal plants, and other difficult-to-propagate species.
• Cell Division & Morphogenesis Studies: Used in controlled laboratory experiments to study the fundamental mechanisms of cytokinin action in plant cell cycle regulation and organogenesis.
• Senescence Delay Research: Applied in post-harvest and physiological studies to investigate the retardation of leaf aging and chlorophyll degradation.
• Seed Germination Enhancement: Formulated in priming solutions to improve germination rates and vigor in certain dormant or slow-germinating seeds.
• Biostimulant & Horticultural Formulations: Incorporated into advanced biostimulant products and in-vitro culture kits for commercial plant production and breeding programs.
• Biochemical Standard & Reference Material: Serves as a high-purity analytical standard for quantifying cytokinin levels in plant extracts via HPLC or LC-MS/MS.
