The activities of isomers of zeatin, ribosyl-zeatin, and 6-(gamma,gamma-dimethylallylamino) purine (i(6)Ade) on the moss Funaria hygrometrica are compared by measuring the ability of the cytokinins to induce callus or gametophores. The cis- and trans-ribosyl-zeatins were inactive, and therefore this kind of bioassay cannot be used as evidence for the presence or absence of a cytokinin in tests on natural products.
