Frequent irrigation regimes and cool storage increased the sensitivity of carnation cut flowers to ethylene which was reflected by a shorter residual flower life. A combination of cytokinins, 0.23 mM kinetin or isopentyl adenine (IPA), with 5% wt/vol sucrose reduced the sensitivity to ethylene and increased longevity 2-2.6 times, respectively. The reversible and irreversible wilting response to ethylene is discussed.
