Abstract

Typically, wilting symptoms are associated with termination of vase life of most cut flowers (8), suggesting that water relations are of importance, especially when it concerns an advanced phase of vase life.

Abstract

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 m<sc>M</sc> kinetin or isopentyl adenine (IPA), with 5% w/v sucrose reduced the sensitivity to ethylene and increased longevity 2 to 2.6 times, respectively. The reversible and irreversible wilting response to ethylene is discussed.

Abstract

In a wide range of microbial populations, flower longevity of untreated stems of Dianthus caryophyllus L. was not different from the sterile water control. However, pretreating stems with 1000 ppm AgNO3 for 30 minutes and placing them in various dilutions of bacterial suspensions extended flower life and greatly reduced bacterial counts in the holding solution. Passing these suspensions through Millipore filters (0.45 μm) resulted in filtrates devoid of microorganisms which also reduced flower life and increased the water deficit of the petals. Silver counteracted the damaging effects of these filtrates.
