| Abstract: | Cytokinin activity was detected by means of the soybean callus test in the scales of Iris hollandica Hoog cultivar ‘Prof. Blaauw’ during the cold treatment for flower formation. A component of the biological activity extracted from the bulb scales coeluted with zeatin riboside when subjected to high-performance liquid chromatography. It is suggested that the cytokinins in the scales may be involved in flower formation. |
