Investigation was conducted under controlled conditions in the laboratory for plant production at the Faculty of Agriculture in Osijek. The cut roses used in the study were „Red Naomi“. Three different mediums of 300 ml volume were used in the study: ordinary tap water, Chrysal clear, Crystal soil gel. After symptoms of decay such as weariness of neck and yellowing and drying of petals were observed, each rose was taken out of medium and the volume of the residual liquid was measured. Leaves, neck and head of decayed roses were separately weighed, placed in paper bags and dried at 70 ºC for 24h and 48h respectfully. The smallest loss of medium volume (5.45 %) was recorded in cut roses that were stored in the Crystal soil gel, while the greatest loss of medium volume (47.71 %) was recorded in cut roses stored in Chrysal clear.
