Cytokinin effect on branching and bud formation in Funaria.
Cytokinins have two different effects on protonemata of Funaria hygrometrica. They induce branching of unbranched caulonemata and bud formation. Branching occurs after treatment with pico-molar concentrations of cytokinins whereas bud formation requires micro-molar concentrations. Both processes are therefore independently stimulated by cytokinins.
