Plants carry out this reaction easily and rapidly, so ribosides appear to have activity on their own, but this is an artifact. Cytokinins have many roles in plants Cytokinins are known from cytokinin-overproducing mutants to produce additional leaves and branches on the stem. The stems and leaves produce additional chlorophyll. Wounding often produces a new branch. Leaf senescence is delayed.
Apical dominance is released.
Cuttings produce adventitious roots slowly and require additional auxin to reliably root. Tumors may form at nodes. The results of applied cytokinins could include release of apical dominance as you demonstrated in kidney beans last week. This effect is useful to produce many tiny plants in what is commonly called micropropagation today. You observed this in your tissue culture project.
