Cytokinins are involved in many plant processes, including cell division and shoot and root morphogenesis. They are known to regulate axillary bud growth and apical dominance. According to the "direct inhibition hypothesis", these effects result from the ratio of cytokinin to auxin. This theory states that auxin from apical buds travels down shoots to inhibit axillary bud growth. This promotes shoot growth, and restricts lateral branching. Cytokinin moves from the roots into the … WebOct 13, 2024 · Cytokinins are a group of hormones that promote cell division in plant roots and shoots and the growth of buds. These hormones have been found in all complex plants as well as mosses, fungi, and ...
