Cytokinins are defined as compounds that have biological activities similar to those of trans-zeatin. These activities include the ability to do the following:
Induce cell division in callus cells in the presence of an auxin
Promote bud or root formation from callus cultures when in the appropriate molar ratios to auxin
Delay senescence of leaves
Promote expansion of dicot cotyledons
