Influence of water quality and chemical compounds on vase life of cut roses.

 

The influence of water quality and different chemical compounds on keeping quality was examined in 2 experiments with Rosa x hybrida cv. Baronesse. Aluminum sulfate, Chinosol and Previcur were used as inhibitors of microorganism growth. Argylene, ASS and AOA were used to reduce ethylene production. The neutral salts potassium dihydrogen-phosphate and sodium chloride were used as osmotic agents. Sugar acted as an energy donor and Chrysal Professional was tested as a commercial cut flower preservative. Decarbonated water extended vase life by 5 days compared with tap water. ASS and Previcur reduced longevity significantly. Regardless of water quality only Chinosol and Chrysal Professional prolonged vase life. The most harmful effect was observed with Previcur and tap water. Chrysal Professional concentration can be reduced to 5.0 g/litre when decarbonated water is used.
