INVESTIGATION OF THE MODE OF ACTION OF ETHYLENE IN CARNATION SENESCENCE

Edward C. Sisler, M. S. Reid, David W. Fujino
The hypothesis that ethylene (C2H4) action in the senescence of carnation (Dianthus caryophyllus L. cv. White Sim) flowers is mediated by a specific C2H4 binding site in the tissues was investigated using 14C-C2H4. A substantial proportion of the bound radioactive C2H4 could be displaced by the addition of unlabelled C2H4, indicating a specific binding site. Low concentrations of 2,5-norbornadiene delayed the senescence of carnation flowers. The contribution of these data to our understanding of the action of C2H4 in cut flower senescence is discussed.
