Abstract
Several tobacco species exhibit a marked sequential leaf senescence in which basal leaves senesce first and then the senescence progresses towards apical leaves. The role of plant hormones, especially cytokinins, in the control of leaf senescence has been reviewed extensively (Van Staden et al. 1988). Cytokinins have been regarded as more effective senescence retardants than other growth substances because of their dramatic and pronounced senescence retarding activity when applied to diverse species (Noodén and Leopold, 1978).
