A portion of the surface of detached Graptopetalum paraquayense E. Walther leaves can be used to assay small amounts of reagents in lanolin for their ability to induce shoots only at the site of application. The cytokinins benzyladenine, kinetin, and 6-(gamma,gamma-dimethylallylamino)purine (DMAAP) were tested, and DMAAP was most effective in bud induction at concentrations below 1%. The higher the hormone concentration, the sooner the appearance of leaf primordia and the higher the ultimate yield of buds. Leaves treated with DMAAP for 2 days developed buds as rapidly as those with longer treatments.
