WebAbstract. Since their discovery in the 1950s, it has been established that cytokinins (CKs) play important regulatory roles in various physiological processes in plants. Only recently have CKs been also implicated in the response of plants to biotic and abiotic stresses. During the last years, several analytical methods have been developed to ... Cytokinins (CK) are a class of plant hormones that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence.
