Abstract
Several cultivars of carnation (Dianthus caryophyllus L.) flowers were successfully cryo-dried and remained naturalistic in appearance after being placed in -80°C for 12 hours and then placed in a freeze-drier for 7 days.
Glycerine (G), clove oil (CO), ethylene glycol (EG), G + dimethylsulfoxide (DMSO), CO + DMSO and EG + DMSO were unsuccessful in an attempt to render the flowers and stems more flexible, less susceptible to breakage and still remain aesthetically acceptable.
The above materials were used as 2 second dips (with or without a wetting agent) as natural stem translocation or translocation uptake under vacuum before cryo-drying.
These chemicals also failed as sprays to render the tissue flexible after cryo-drying.
