Abstract
A method for preserving a cut flower involving only an easy and simple procedure, whereby the cut flower can maintain qualities similar to those of the natural state for a long period of time, and a method for manufacturing a processed cut flower that can maintain qualities similar to those of the natural state for a long period of time. The method for preserving a cut flower by replacing the tissue fluid of the cut flower by a preservative solution includes the steps of: (1) a first replacement step in which the tissue fluid of the cut flower is replaced by a hydrophilic organic solvent; and (2) a second replacement step in which the hydrophilic organic solvent having replaced the tissue fluid in the cut flower is replaced by the preservative solution of an organic solvent that has an affinity for the hydrophilic organic solvent and is nonvolatile or hardly-volatile.
