Comparative Activity of Isomers of Zeatin and Ribosyl-Zeatin on Funaria hygrometrica1

Luretta D. Spiess

a Department of Biology, Lake Forest College, Lake Forest, Illinois 60045

The activities of isomers of zeatin, ribosyl-zeatin, and 6-({gamma},{gamma}-dimethylallylamino) purine (i6Ade) 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.
