Abstract

PROBLEM TO BE SOLVED: To preserve various cut flowers in excellent freshness by dipping a cut part side of the cut flower in water containing fibrous activated carbon. SOLUTION: In preserving a cut flower by dipping a cut part side of the cut flower in water or water mixed with a nutritive agent, a freshness preserving material containing fibrous activated carbon as a main component is dipped in the water. Preferably, the fibrous activated carbon as the main component of the freshness preserving material has 500-2,000m<2> /g specific surface area and >=90% of total pore volume in the material has <=30Å pore diameter. Preferably, the freshness preserving material contains silver and/or an inorganic silver compound. By using the composition, an aging hormone such as ethylene can efficiently be adsorbed and removed, and further, a bent neck phenomenon can also be suppressed by addition of silver.

In particular, rose, orchid, carnation, sweet pea, gerbera, etc. are markedly accelerated by ethylene.

[0003] Substances that inhibit the action of ethylene or inhibit biosynthesis are known, and some of them are used as quality preservatives for cut flowers. As the action inhibitor, a silver thiosulfate anion complex is mainly used, and as the biosynthetic enzyme inhibitor, aminoethoxyvinylglycine, aminooxyacetic acid, and the like are mainly used.

The silver thiosulfate anion complex is widely used because it is inexpensive and has a high effect on maintaining the quality of many cut flowers. However, since its main component is silver ion, it may cause environmental pollution, and its use is being regarded as a problem. Therefore, biosynthetic enzyme inhibitors such as aminoethoxyvinylglycine and aminooxyacetic acid have been used as an alternative to the silver thiosulfate anion complex. Not only is it more expensive,
There is a problem that there are few types of flowers that show an effect.

[0005] Water for storing cut flowers contains nutrients and fungicides in addition to ethylene action inhibitors and biosynthetic enzyme inhibitors. Sucrose, which is a kind of oligosaccharide, is generally used as a nutrient, and sucrose reduces the amount of water absorbed by cut flowers and increases the amount of respiration to extend the viewing period. Bactericides are added to prevent short-lived flowers, causing a bent neck phenomenon in which bacteria block the conduits near the cut ends of cut flowers and hinder water absorption.

Further, a method has also been used in which biosynthesized aging hormone such as ethylene is physically adsorbed by granular activated carbon to prolong the flower life of cut flowers. However,
In this method, too, since ethylene action inhibitors, nutrients, bactericides, etc. are used to maintain freshness together with granular activated carbon, nutrients and other components are adsorbed on the granular activated carbon having micropores and macropores, and granular activated carbon is absorbed. It was difficult to adsorb ethylene effectively with activated carbon. Activated carbon also has the problem that it may promote the growth of bacteria, which adversely affects the freshness of cut flowers.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. The freshness preserving material for cut flowers of the present invention is a sheet or a molded body containing fibrous activated carbon as a main component. Examples of the fibrous activated carbon include coal pitch-based, petroleum pitch-based, rayon-based, phenol fiber-based, and polyacrylonitrile fiber-based. ,
Alternatively, a vinylon type or the like can be used.
The specific surface area of the fibrous activated carbon used in the present invention is preferably from 500 to 2000 m 2 / g as measured by the BET method. When the specific surface area is less than 500 m 2 / g, pores become small, and the amount of adsorbed aging hormone such as ethylene tends to decrease.
On the other hand, when the specific surface area exceeds 2000 m 2 / g, the pores become too large, so that nutrients useful for flowering are easily adsorbed, and accordingly, the adsorption of aging hormone such as ethylene tends to decrease.

Further, fibrous activated carbon is manufactured by B.I. J. In the pore distribution obtained by the H method (the method of Barrett, Joyner, Halenda et al.), The proportion of the volume occupied by pores having a pore diameter of 30 ° or less is preferably 90% or more of the total pore volume.
When the pore volume is less than 90%, the number of large pores that absorb nutrients useful for flowering increases, and for example, pores with a pore diameter of 30 mm or more such as commonly used granular or powdered activated carbon are used.
When present in an amount of 20 to 30%, even useful nutrients are adsorbed, and the selective adsorption of aging hormone such as ethylene is reduced.

According to the method for preserving freshness of cut flowers of the present invention, the freshness preserving material containing fibrous activated carbon as a main component is immersed in water to which a nutrient is added as required, and the cut side is immersed in the water. And save the cut flowers. Since the freshness preserving material used in the present invention is mainly composed of fibrous activated carbon having a higher micropore ratio than granular activated carbon, when preserving cut flowers by immersing the cut side, nutrients useful for flowers can be obtained. Without adsorbing, aging hormones such as ethylene can be efficiently adsorbed and removed, and the flower life can be prolonged. In addition, since the freshness preserving material used in the present invention is mainly composed of fibrous activated carbon, it is necessary to not only adsorb and remove aging hormones such as ethylene and harmful substances secreted from cut flower stems, but also maintain dissolved oxygen in water. It is also possible to increase the flower life by increasing the respiration of cut flowers.

In the method for maintaining freshness of cut flowers according to the present invention,
If a freshness-maintaining material containing fibrous activated carbon as a main component is used in water for a long period of time, there may be a problem that bacteria grow in the water and cause a vent neck phenomenon. In order to prevent such a problem from occurring, a freshness maintaining material containing silver or an inorganic silver compound or both silver and an inorganic silver compound may be used. In other words, if cut flowers are preserved using a freshness-preserving material containing silver and / or an inorganic silver compound, even when preserved in water containing nutrients, the growth of bacteria can be suppressed by the antibacterial effect of silver. Therefore, the bent neck phenomenon can be more easily and safely suppressed, and the period for viewing cut flowers can be further lengthened.

According to the present invention, if cut flowers are preserved using the cut flower freshness preserving material, aging hormones such as ethylene, which make cut flowers less durable, can be efficiently used without adsorbing nutrients useful for flowers. It is also possible to maintain dissolved oxygen in water, so that the flower life can be prolonged by increasing the respiration of cut flowers. Furthermore, if a material containing silver and / or an inorganic silver compound is used as a freshness preserving material, the growth of bacteria can be suppressed by the antibacterial effect of silver. The phenomenon can be suppressed, and the cut flowers can be kept more fresh.
