JPH08224046A - Preservation method for flower - Google Patents

Abstract

PURPOSE: To provide an excellent mixture of gas components capable of preserving the life of cut flowers for a long time in a beautiful state. CONSTITUTION: This mixture is composed of nitrogen of 28-79.8%, carbon dioxide of 20-70% and oxygen of 0.1-2%. Using of the mixture for preservation of flowers can prevent spot formation, withering and over opening of flowers. Enabling the preservation of flowers such as roses, etc., for a long time, this method can be conveniently applied on all processes through from a producer to a florist including transportation, distribution, display, etc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of vividly preserving the life of cut flowers of a flower.

[0002]

2. Description of the Related Art For the purpose of maintaining the freshness of vegetables, low temperature treatment and adjustment of ambient environmental gas are generally used (preserving the freshness of vegetables, Yokendo, 1986). In addition, as a means for prolonging the life of cut flowers, a material that removes harmful gases such as ethylene and retains freshness (JP-A-1-148341), a preservative that utilizes plant hormones (Japanese Patent Publication No. 2-108601), and a preservative is added to the water. How to control corruption (Japanese Patent Publication No. 2-4001)
Etc. are also disclosed.

[0003]

Many of the commercially available cut flower life-prolonging agents used in the market are dissolved in water and used (Japanese Patent Laid-Open No. 2-108601), but the storage period is limited to about 6 days. It was There is also a method in which flowers are enclosed in a container to serve both as a storage and an exhibition. However, this method has drawbacks such as wilting during the storage period and spots on the petals, and is unsatisfactory for storing cut flowers of roses.

[0004]

[Means for Solving the Problems] Oxygen concentration 0.2% to 2.0%, carbon dioxide concentration 20 to 70%, nitrogen concentration 2
A mixed gas consisting of 8 to 79.8% is prepared. In advance
It is desirable to fill the cylinder with the mixed gas having this ratio. Introduce this mixed gas into a bag containing cut flowers.
Encapsulate. Although it has a life prolonging effect even at room temperature, lower temperatures give better results. It is desirable that the cut end be filled with water.

[0005]

[Function] Hypoxia slows down the metabolic activity of flowers, and carbon dioxide inhibits rose tissue from producing ethylene. These two components work synergistically and help preserve the vitality of the flower itself.

[0006]

EXAMPLES The details of the present invention will be described below with reference to examples.

Example 1 200 ml of distilled water was added to a 1000 ml glass cylindrical container, and 10 rose cut flowers (bridal pink) were inserted. This glass cylindrical container was filled with the gas components having the compositions shown in Table 1 (Example 1, Example 2, and atmospheric composition) several times to change the gas phase.

[0008]

[Table 1]

The container was allowed to stand at room temperature of 5 to 20 ° C. for 4 days, and the degree of petal spots was observed. When replaced with normal atmospheric composition and nitrogen (99% pure), all 10 spots were spotted. In contrast, the composition of the present invention produced only spots on one cut flower (Table 2).

[0010]

[Table 2]

Example 2 100 ml of distilled water was added to a 1000 ml cylindrical container made of vinyl, and 10 rose cut flowers (bridal pink) were inserted. This glass cylindrical container was filled with the gas components of Examples 1 and 3 of Table 1 and the atmospheric composition several times to change the gas phase. The container was left at room temperature of 5 to 20 ° C. for 10 days, and the degree of petal wilting and excessive opening was observed. If replaced with normal atmospheric composition and nitrogen of Example 1 (99%),
Wilting occurred in 10 and 6. In contrast, with the composition of the present invention, such wilting was not observed (Table 3).

[0012]

[Table 3]

[0013]

EFFECTS OF THE INVENTION By using a gas component in the present invention, it is possible to prevent spots, atrophy and over-opening of cut rose flowers, and to store roses for a long period of time. It can be used for transportation and display.
