Description

Para-Topolin Riboside (Ptr) is a synthetic cytokinin plant growth regulator, a ribosylated derivative of the aromatic cytokinin para-topolin. This compound is valued for its high biological activity and stability, making it a crucial tool in plant tissue culture and agricultural biotechnology. It is primarily used by researchers and commercial producers in the plant science, horticulture, and agricultural chemical industries to promote cell division, shoot proliferation, and delay senescence in a wide range of plant species.

Application

• Plant Tissue Culture Media: A key component in Murashige and Skoog (MS) and other media formulations for efficient micropropagation and organogenesis.
• Horticulture and Floriculture: Used to enhance shoot multiplication, improve rooting efficiency, and increase the yield of ornamental plants, fruits, and vegetables.
• Agricultural Biotechnology Research: Serves as a critical reagent in studies of plant physiology, senescence, and cytokinin signaling pathways.
• Seed Germination and Vigor: Applied to improve germination rates and early seedling growth under various environmental conditions.
• Cell Suspension Cultures: Employed to maintain healthy and proliferating plant cell cultures for secondary metabolite production.
• Genetic Transformation Studies: Facilitates the regeneration of transgenic plants following Agrobacterium-mediated or biolistic transformation.
