Description

Thidiazuron is a highly effective plant growth regulator belonging to the phenylurea class of cytokinins. Its primary value lies in its potent ability to induce cell division and promote callus formation, making it a critical tool in plant tissue culture and agricultural biotechnology. This compound is essential for researchers, biotechnologists, and agrochemical manufacturers focused on plant propagation, yield enhancement, and the development of novel plant varieties. Thidiazuron CAS NO 51707-55-2 is recognized for its unique biological activity at low concentrations.

Application

• Plant Tissue Culture: Widely used as a cytokinin to induce shoot proliferation, somatic embryogenesis, and callus growth in a variety of plant species, including woody plants and ornamentals.
• Cotton Defoliation: Acts as a chemical defoliant to facilitate mechanical harvesting of cotton by promoting leaf abscission.
• Fruit Thinning: Applied in orchards to improve fruit size and quality by regulating fruit set and reducing cluster density.
• Weed Control Research: Studied for its herbicidal properties and its role in understanding plant hormone pathways and senescence.
• Biotechnological Research: A key reagent in laboratories for studying plant cell totipotency, gene expression, and developmental biology.
• Ornamental Horticulture: Used to stimulate lateral bud break and enhance the branching and aesthetic quality of ornamental plants.
