Auxins. It is one of the major classes of plant hormones that influence plant growth as well as the development of new plants. Chemical Nature WebCytokinins stimulate growth of cotyledons of Lepidium, cucumber and soybean. It induces cell division leading to increase in fresh weight. Cytokinins also retard leaf senescence through chlorophyll retention. Some workers have also used Sephadex LH—20 partition system for the purification of cytokinin.
