The application discloses a
preservative solution for prolonging the life of
cut flowers of
Impatiens walleriana and a preparation method thereof, and relates to the field of
postharvest preservation technology of
Impatiens walleriana. The
preservative solution is composed of glucose,
gibberellin, 8-hydroxyquinoline
sulfate,
citric acid and deionized water in a specific proportion, wherein the glucose is 3.0% (w / v), the
gibberellin is 25 mg / L, the 8-hydroxyquinoline
sulfate is 100 mg / L, the
citric acid is 80 mg / L, and the balance is deionized water. When the
preservative solution is prepared, the
gibberellin is first dissolved in
anhydrous ethanol to prepare an
alcohol-soluble
mother liquor, the 8-hydroxyquinoline
sulfate is dissolved in deionized water to prepare an aqueous
mother liquor, and then the glucose and the
citric acid solution are mixed step by step and constant volume is performed, so that a uniform transparent preservative solution is finally prepared. According to the scheme, the
cell membrane integrity of the
cut flowers of
Impatiens walleriana can be effectively maintained,
petal browning and water loss can be delayed, the best viewing period and the
vase life of the
cut flowers can be significantly prolonged, the commodity value can be improved, raw materials are conventional, the process is simple, and the scheme is suitable for large-scale application.
