Problems solved by technology

The fresh-keeping effect and physiological effect of the composite preservative of 6-BA and other phytohormones on cut flower lily have been reported, but there are also reports pointing out that the fresh-keeping effect of 6-BA treatment on some cut flower species is generally not good

Embodiment Construction

[0031] The fresh-cut fresh-cut lily flower preservation method provided by the invention is based on the preservation effect of TDZ on the fresh-cut lily flower, thereby improving the lifespan and quality of the fresh-cut lily flower. The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0032] TDZ (N-phenyl-N'-1,2,3-thiadiazole-5-urea) is a synthetic non-metabolic phenylurea derivative that has been sold in the market; the specific choice is to import from Sigma Aliquoted TDZ reagent.

[0033] Although there are many kinds of lilies, the fresh-keeping effect of TDZ is based on their cell activity, so the influence of the variety is not very great; the specific choice is 'Sorbonne' lily (Lilium oriental'Sorbonne') among the more common hybrid varieties of oriental lily. illustrate.

Abstract

The invention discloses a fresh-keeping method for a lily fresh cut flower. The method comprises steps of: 1) cutting lily to be picked, and retaining sufficient branch length, wherein a lower cut surface is a slope surface, and upper and middle leaves are kept; 2) after cutting, immediately inserting a lower end of the lily branch downwards into a fresh-keeping liquid containing TDZ for fresh-keeping pretreatment; and 3) pretreating the lily in the fresh-keeping liquid for 12-24 h, and changing the fresh-keeping liquid into clean water. The TDZ can prolong vase life of the lily cut flower, increase the maximal diameter of flower (promoting growth of bud diameter) and delay formation time of the maximal flower diameter; the TDZ treatment can delay degradation of chlorophyll and keep the chlorophyll content at a high level for a long time, thereby delaying leaf senescence of the cut flower; and the TDZ treatment can inhibit respiration of the lily cut flower during a vase period, reduce sensitivity of the lily to ethylene, reduce ethylene release rate of the flower and delay an absorption peak and an ethylene release peak.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping lilies, and relates to a fresh-cut lily fresh-keeping method. Background technique [0002] Lily is an ethylene-sensitive flower, which is very easy to senescence, and it is easy to be induced by environmental stress during post-harvest storage and transportation to induce ethylene production, which accelerates the senescence of cut flowers and greatly affects its economic benefits. According to reports, fresh-cut flowers can be value-added by 20-40% after fresh-keeping treatment during storage and transportation. Therefore, it is of great economic value and practical significance to study the fresh-keeping of cut flowers of lily. The preservation of lily cut flowers is mainly chemical preservation, and at the same time, the effect of phytohormone preservation is better. At present, cytokinins are the most widely used phytohormones in lily cut flower preservation. [0003] Cytokinin (CTK) ...
