摘要：Living plants, in particular coniferous plants, with the exception of Picea, Abies, Tsuga; Larix, Taxus and Cedrus genuses, are preserved in that they are caused to suck up a preservative liquid which is based on glycerine and water in the tolume proportions of 18:82 to 35:65 and contains dyestuffs for replacing the color of the plant parts after the preservation. The dyestuffs are to comprise, apart from a blue and possibly also a red dyestuff, tartrazine (C.I. 19140, E102) in a concentration of from 2-10 g/I of preservative liquid. The blue dyestuff comprises preferably patent blue V (C.I. 42051, E131) in a concentration of from 0.1 to 0.8 g/I and the red dyestuff most preferably of new coccine (C.I. 16255, E124) in a concentration of from 1 to 20 g/I. The relative concentrations between the different dyestuffs are adapted into conformity with the sought-for color of the preserved plant. The preservative liquid may advantageously also contain at least one plant nutrient substance, in particular a water-soluble potassium salt, preferably potassium nitrate in a concentration of from 1 to 15 g/I. The preservation is effected at a temperature of from 15 to 33° C in a current of air at a relative humidity of at most 60%, the preservative liquid preferably being a few degrees centigrade warmer than the
current of air. It is advantageous to add, to the preservative solution, an amphoteric sulphonated surface active agent in an amount of from 0.2 to 1.5 vol.-% in order to attain a shaded coloring of young and old shoots. It is also advantageous to adapt the pH and conductivity of the preservative solution to the analysed pH and conductivity Of the plant stock subjected to preservation.
