Abstract
The effects of dry handling and the use of hydration solution (HydraflorTM) on the postharvest quality of cut flowers of four rose cultivars (Freedom, Opera, Red alfa and Red vicer) were assessed. After treatment, the stems were stored at 4 °C and 90 % relative humidity for 10 and 20 days, after which they were placed in a vase containing tap water or Crystal ClearTM preservative solution and then evaluated for fresh weight, flower opening, water uptake and vase life. The results show that vase life increases in dry-handled stems compared with those treated with HydraflorTM. The storage period significantly affected flower opening, which fell by 17.2 % with the change from 10 to 20 days of storage. Finally, dry handling is recommended for the rose stems of the cultivars evaluated, as it reduces costs and maintains the end quality of the flower.
