<p>The present invention is a treatment method for preserving cut flowers, which has a dehydration process for removing the tissue water of cut flowers using a solvent, and a permeation process for letting polyethylene glycol permeate after dehydration, to substitute the solvent by polyethylene glycol, characterized in that the dehydration process is effected while the cut flowers are fixed in a container having a proper amount of a molecular sieve spread over its bottom and filled with a solvent having a specific gravity smaller than that of water, wherein the specific gravity of the solvent is measured to monitor the change of the solvent in dehydratability, and the time when the specific gravity suddenly rises is detected as the time for exchanging the molecular sieve for a new one, to restore the dehydratability of the solvent, thereby allowing the solvent to be used continuously and allowing the dehydration process to be continued without waste of time.</p><p>Furthermore, if a washing process for washing the cut flowers containing polyethylene glycol as a substitute of the tissue water by a solvent not containing polyethylene glycol is added, the stickiness of the cut flowers otherwise caused after a drying process can be prevented.</p> |
