Kinetin is an adenine-type cytokinin phytohormone that is used in plant culture media such as Murashige & Skoog media in conjunction with auxins such as indole-3-acetic acid (IAA), indole-3-butyric acid (IBA), 1-napthaleneacetic acid (NAA) or others to induce the fomation of callus and to regenerate plant tissues from callus.
