<p>Method of processing cut plant material esp. for preserving leaves, stems or flowers for decorative purposes, comprises immersing the plant material in a liq. polyol compsn. with a specific gravity of 1.10-1.16, applying a pressure of 5-40 (pref. 18-24) psi for 2-7 DEAB- DE3126621 C Process for preservation of plant samples comprises immersing the plant cuttings in a liq. polyol (density 1.10-1.16 g/cm3) under slight pressure (1.34-3.75 bar) at room temp. for 2-7 days the plant tissues are then removed, freed from excess polyol and dried. - Pref. polyols are glycerol, ethyleneglycol, diethyleneglycol, triethyleneglycol and their mixts.</p> |
