Which plant hormone promotes the growth of the plant? One example of a hormone produced by a plant that encourages the development of the plant is called auxin. Auxins encourage the growth of longer stems but suppress the development of lateral buds (maintains apical dominance).
WebCytokinin promotes shoot and inhibits root development (Werner et al. 2003), while auxin is known to stimulate root and inhibit shoot growth (Kurepa and Smalle 2024). Further, auxin and cytokinin also act as antagonists in the regulation of meristem maintenance and organ differentiation in root and shoot apical meristem (Su et al. 2011 ...

In plants, cytokinins, a group of phytohormones derived from adenine, stimulate cell proliferation. Cytokinin signaling is initiated by membrane-associated histidine kinase …
WebFeb 23, 2009 · Abstract. The hormone cytokinin promotes cell differentiation in plant roots by repressing both auxin transport and responses to auxin at the boundary between the meristem and the root elongation zone. In plants, populations of undifferentiated cells called meristems serve as the source of all new growth throughout post-embryonic development.
