Light and electron microscopy revealed no stimulation of oleosome disappearance or chloroplast development associated with zeatin‐enhanced growth of excised radish cotyledons. Accelerated protein body breakdown was the only detectable effect of zeatin treatment. Isocitrate lyase activity, disappearance of total lipids, and appearance of galactolipids, phospholipids, and chlorophyll were unaffected by zeatin. Results indicate that cytokinins do not accelerate conversion of radish cotyledons from storage to photosynthetic organs.
