The interaction of kinetin and indolebutic acid on the rooting of cuttings

The object of this study is to understand what effect the interaction of indolebutyric acid and kinetin would have on the rooting of cuttings. If an interaction should show up it might provide a clue for methods of inducing roots on cuttings which are difficult to root. In some cases, as noticed in tobacco pith tissue, kinetin increases callus formation and rooting from callus tissue is sometimes easier than from more differentiated tissue.
