Abstract
The present invention describes a method for treating one or more cut flowers each including a stem, possibly leaves and a flower bud, said method comprising—arranging one or more cut flowers in an impregnation solution so that at least a portion of the stem of said one or more cut flowers are immersed in the impregnation solution, but where the flower bud is free from impregnation solution; and—applying vacuum impregnation or pressure impregnation, preferably vacuum 10 impregnation, to the impregnation solution when said at least portion of the stem are immersed into the impregnation solution.
Claims22
A method for treating one or more cut flowers comprising the steps of:
- providing said one or more cut flowers, each comprising at least a stem and a flower bud;
- arranging and partially immersing each of said one or more cut flowers in an impregnation solution so that at least a portion of the stem of said one or more cut flowers are immersed in the impregnation solution, wherein the step of partially immersing comprises excluding the flower bud from being immersed in the impregnation solution;
- and
- applying vacuum impregnation to the impregnation solution during said step of partially immersing when said at least portion of the stem are immersed into the impregnation solution, said vacuum impregnation being applied in at least three phases which are a falling step when the pressure is decreased to a certain minimum pressure, then a holding step in which the minimum pressure is kept or substantially kept, and a pressure rising step where the pressure is increased to atmospheric level;
- and
- wherein the impregnation solution comprises at least a surfactant, and wherein the method involves vacuum impregnation in a minimum pressure range of 50-500 mbar.
