Cytokinins in cut carnation flowers. II. Relationship between endogenous ethylene and cytokinin levels in the petals



Cytokinins in cut carnation flowers. II. Relationship between endogenous ethylene and cytokinin levels in the petals



Plant Growth Regulation 5(2): 75-82



Zeatin-O-glucoside, zeatin, ribosylzeatin, dihydrozeatin, iso-pentenyladenine and iso-pentenyladenosine were detected in the petals of White Sim flowers by HPLC and radioimmunoassay techniques. Dihydrozeatin is apparently responsible for most of the biological activity. Within the petals most activity was detected in the basal parts which senesced much slower than the upper parts of the petals.
