Abstract

The invention discloses a cut flower fresh-keeping agent which is composed of 1 to 3 wt% of sugar, 0.1 to 0.3 mmol.L of 8-hydroxyquinoline salt and 30-120 mu mol.L of resveratrol and / or sodium nitroprusside. The invention provides a scientific basis for the application of sodium nitroprusside on the cut flower fresh-keeping; the cut flower fresh-keeping agent prepared by pure natural plant extractive resveratrol delays the ageing process of cut flowers, prolongs vase life, and effectively avoids toxic action of Ag and other injurants on the environment; and the resveratrol has wide source, and is economic and practical, natural and environmental-friendly, and safe and stable, thus having wide application prospect in the future gardening post harvest industry when being used to prepare cut flower fresh-keeping agent.

Description

technical field [0001] The invention belongs to chemical fresh-keeping technology, and in particular relates to a fresh-keeping agent for cut flowers. Background technique [0002] Cut flowers usually refer to the general term of flowers, flower branches, leaves, etc. cut from plants. They are the materials for flower arrangement, also known as flower materials, and are used for flower arrangement or making flower decorations such as bouquets, flower baskets, and wreaths. The four traditional cut flowers include roses, lilies, carnations, and gladiolus. [0003] For a long time, the research on the aging process and mechanism of cut flowers has been relatively active at home and abroad. However, there are many varieties of cut flowers, and there are great differences in metabolism among varieties, and there is no effective broad-spectrum preservative. At present, the fresh-keeping method of cut flowers is mainly chemical preservation. Most of the preservatives contain ethyl...
