cytosiinin
Cytosiinin is a synthetic plant growth regulator that belongs to the cytokinin class of plant hormones. It is chemically known as N-(2-chloro-4-pyridinyl)-N'-phenylurea. Cytosiinin has been developed and used primarily for its ability to promote cell division and differentiation in plants. Its applications in agriculture and horticulture include stimulating rooting in cuttings, enhancing fruit set, and improving the overall yield and quality of various crops. It is often used in tissue culture techniques to induce callus formation and organogenesis. The efficacy of cytosiinin can depend on the plant species, concentration, and timing of application. It works by mimicking the action of natural cytokinins, which play a crucial role in plant development by influencing processes such as shoot formation, leaf senescence, and nutrient mobilization. Research into cytosiinin and other synthetic cytokinins continues to explore their potential for optimizing plant growth and addressing challenges in food production.
