WebPhytohormones are plant hormones. They are organic substances that facilitate regulating the growth of a plant and its development. Plant hormone signals are incorporated at the gene-network level, and their signaling pathways act non-redundantly. Examples are auxin, gibberellins, cytokinins. WebCytokinins are rapidly metabolized in plant tissues (Auer, 2002). Immediately after harvest and during the initial period of storage, exogenous cytokinins have no effect on dormancy (Turnbull and Hanke, 1985a; Suttle, 2002). As storage was extended, tubers developed a time-dependent increase in cytokinin sensitivity.
