Cytokinins (cytokinin, CTK) isolated from corn or other plants or synthetic plant hormone. General plant roots produce, it is a class of substances to promote cytokinesis mitogen promoting differentiation and growth of various tissues. A synergistic effect with auxin. Regulate plant cell growth and development of plant hormones. Cytokinins play a role in the activation of cell division, it is also included in cell growth and differentiation and other related physiological activities, such as kinetin (KT), zeatin (ZT), 6- benzylaminopurine (6-BA ) and so on. The most obvious physiological role of cytokinin in two ways: First, to promote cell division and differentiation regulation. In tissue culture, the ratio of cytokinin and auxin affects plant organ differentiation plant cytokinin factory, usually when a high proportion, in favor of buds; low proportion when conducive to root differentiation. Second, slow down the degradation of plant proteins and chlorophyll mitogen quality, delay aging. There are differences between the various cytokinin activity, such as growth-promoting biological tests, such as natural cytokinin zeatin, isopentenyladenine, than synthetic cytokinin such as 6-benzylaminopurine and excitement Prime high, and in delaying the decomposition of chlorophyll biological tests, which activity higher than the former.
