Abstract
A process for preserving green colored plant tissues while retaining the natural green color thereof, in which the tissues are immersed in a relatively inexpensive solution comprising up to about 90% water, at least one monohydric alcohol, at least one preservative component such as sulphurous acid, and sufficient buffering and mordant reagents such as citric acid and cupric salts such as cupric chloride and cupric sulphate, to control the pH and osmolality of the solution and so as to permanently retain the natural green color in the tissues.
