Abstract/Summary

The vase life of Rose (Rosa sp.) cut flower, in an indoor house environment, soaked in different concentrations of Sodium hypochlorite, Silver thiosulfate, or sucrose solutions were monitored for seven days. These treatments only extended vase life longevity by one day compared to the control of tap water. The best treatment of Sodium hypochlorite was 1.2 mM (120 drops/gallon), which promoted leaf health and inhibited petal discoloration and wilting. For Silver thiosulfate the best concentration was 0.5 mM, which inhibited petal discoloration and wilting. While for sucrose, the best treatment was 467.4 mM, which considerably inhibited petal discoloration and wilting, promoted leaf and stem health, and liquid media cleanliness. Overall, 467.4 mM (160 g/L) sucrose offers the best vase life maintenance capabilities as a stand-alone preservative.
