Description

Technical Field

[0001] This invention provides a method, particularly a method for reducing the strong fragrance of cut Oriental lilies and OT lilies, belonging to the field of flower cutting and vase arrangement technology. Background Technology

[0002] Lilies are one of the world's five major cut flowers, leading the domestic flower market in both sales volume and revenue. Currently, the cut lily varieties on the market include: strongly scented Oriental lilies and OT lilies, lightly scented LA lilies, and unscented Asiatic lilies. Among these, Oriental and OT lilies have a particularly strong fragrance, which can easily cause dizziness and other discomfort in enclosed environments after prolonged exposure. Research has found that the fragrance of lily flowers mainly comes from the petals, and the aroma components are primarily monoterpenes and phenylpropanoids. Monoterpenes are mainly synthesized via the mevalonate pathway (MVA pathway). 1-deoxy-D-xylulose-5-phosphate synthase (DXS) is the first rate-limiting enzyme in the mevalonate (MEP) pathway and plays a crucial regulatory role in the synthesis of monoterpenoid aroma compounds. To reduce the strong aroma of Oriental lilies and OT lilies, the synthesis of monoterpenoid compounds can be inhibited, thereby weakening their strong aroma. Summary of the Invention

[0003] To address the problem that the strong fragrance of existing Oriental lilies and OT lilies can cause dizziness, nausea, and other discomfort, this invention provides a method for reducing the strong floral fragrance of cut Oriental lilies and OT lilies.

[0004] This invention is achieved through the following technical solution: a method for reducing the strong floral fragrance of cut Oriental lilies and OT lilies, characterized by comprising the following steps:

[0005] (1) Prepare a dichloroisoxane solution with a mass concentration of 0.036% to 0.045% and store it at room temperature;

[0006] (2) Add 5g of preservative to 500ml of dichloroisoxane solution prepared in step (1) to prepare dichloroisoxane bottle insert containing 1% preservative by mass.

[0007] (3) Insert the cut flowers of Oriental lily and OT lily on the first day of bloom into the vase solution in step (2). After 24 hours of vase arrangement, the strong fragrance of Oriental lily and OT lily cut flowers will be reduced.

[0008] Both the dichloroisoxane solution and the preservative are commercially available products.

[0009] The present invention has the following advantages and effects: By using the above-mentioned scheme, the activity of 1-deoxy-D-xyulose-5-phosphate synthase in cut flowers of Oriental lilies and OT lilies can be effectively inhibited by using only a vase solution containing 1% preservative dichloroisoxane. It also plays an important regulatory role in the synthesis of monoterpenoid aroma compounds, effectively reducing the strong aroma of cut flowers of Oriental lilies and OT lilies, and solving the problem of discomfort caused by prolonged contact with these types of lilies. Detailed Implementation

[0010] Unless otherwise specified, all components of this invention are commercially available products.

[0012] Example 1

[0013] A method for reducing the strong fragrance of cut Oriental lilies includes the following steps:

[0014] (1) Prepare a 0.036% dichloroisoxane solution and store it at room temperature;

[0015] (2) Take 500ml of the dichloroisoxane solution prepared in step (1), add 5g of preservative, and prepare a dichloroisoxane bottle insert containing 1% preservative.

[0016] (3) Cut flowers of the Oriental double-flowered lily 'Ice Beauty' on the first day of bloom were inserted into the dichloroisoxane vase containing 1% preservative in step (2). After 24 hours of vase insertion, the fragrance of the flowers was detected by conventional GC-MS method. The results showed that the absolute abundance values ​​of the characteristic ions of the Oriental double-flowered lily 'Ice Beauty' were: myrcene, ocimene, γ-terpinene, linalool, (3E,5E)-2,6-dimethyl-1,3,5,7-octatetraene, and allocirrhene. The results are shown in Table 1.
