JP2002212003A - Freshness retaining agent for cut flower - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a freshness retaining agent for cut flowers capable of keeping not only antimicrobial activities and harmless to human and domestic animals but safe for environmental pollution to retain freshness of cut flowers as it has been pointed out that a chlorine-based agent or a chemical controlling agent containing a heavy metal which has been used as a freshness retaining agent for cut flowers causes generation of chlorine gas though in a minute amount and a fear of cancer generation. SOLUTION: This freshness retaining agent for cut flowers is obtained by bringing a mixed agent made by mixing hydroxyisoxazole with an effective component of chitosan to include a nutrient agent mainly comprising a sugar such as sucrose or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agent for preserving the freshness of cut flowers which prevents rot of stems and leaves of cut flowers in water and obstruction of conduits of stems to prevent depletion of nutrients in order to maintain freshness of cut flowers. It is.

[0002]

2. Description of the Related Art Conventionally, measures for maintaining freshness of cut flowers include:
Prevention of senescence of cut flowers has been required by disinfecting the cut flowers themselves with sufficient amount of fungicides, foliage landing and appropriate nutritional supplementation.

For this reason, chlorine-based chemicals and silver compound agents containing heavy metals have been widely used for a long time to prevent clogging of foliage conduits due to the occurrence of various bacteria after pruning and to improve the efficiency of landing. I have. At present, the use of chemical control agents such as phytohormones has been introduced for plants harvested from buds harvested from plants or cut flowers after flowering. And as a nutrient source, it was usual to supply saccharides.

[0004]

When using a chemical used as a freshness preserving agent for cut flowers, it is a matter of course that the chemical must be used with due consideration to the environment.

[0005] One of the conventional freshness preserving agents is a chlorine-based agent. This may cause the generation of chlorine gas during use. In addition, the use of silver compounds containing heavy metals, which are said to be effective in sterilizing effects, preventing clogging of conduits, and promoting water absorption, has been restricted from now on. Some of the plant hormones used as chemical control agents have been approved for use in Japan, but some have been banned from use in other countries because of their strong carcinogenicity. Japan will be banned in the future.

[0006] Therefore, the occurrence of various fungi accompanying the freshness deterioration of cut flowers significantly reduces the commercial value.

Therefore, in order to maintain the activity of cut flowers, nutrients are actively replenished, the role of the foliage conduit is sufficiently maintained to prevent the propagation of various bacteria, and the treatment agent itself has antibacterial properties. It has been an issue to provide a freshness preserving agent that is continuously harmless to humans and animals and is safe against environmental pollution.

An object of the present invention is to eliminate the above-mentioned drawbacks and disadvantages, and to provide an environmentally friendly, safe and reliable freshness preserving agent for producers.

[0009]

Means for Solving the Problems In order to achieve the above-mentioned objects and objects, we have repeatedly conducted various tests and made intensive studies. As a result, it has been found that a long-term effect of maintaining freshness of cut flowers can be obtained.

The present invention provides a treatment solution obtained by mixing hydroxyisoxazole, a soil fungicide having high water solubility and capable of raising hair, and a chitosan active ingredient having an immunopotentiating activity, which has a function of protecting against infection by microorganisms and pathogenic bacteria. Dedicated research on cut flower freshness preservatives containing cut flower nutritional supplements,
It is a cut flower freshness preservative characterized by finding a long-term freshness preserving effect.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples. A mixture of hydroxyisoxazole solvent and chitosan, which provides a protective function against pathogenic bacteria, which have been shown to have physiological effects such as promoting root growth and activation by applying to the roots of piloerected plants. Then, a freshness preserving agent containing a nutrient source such as sucrose is used as a treatment liquid.

The cut solution of the foliage is submerged by utilizing the cut flowers in the treatment liquid of the present invention configured as described above. The foliage that has absorbed the treatment liquid inhibits the growth of pathogens and hyphae and the formation of spores in the foliage conduit, thereby eliminating clogging in the conduit of cut flower foliage, and the treatment liquid quickly passes through the conduit. ,
Sucrose and the like added as a nutrient source can be easily transferred in the conduit, giving vitality to cut flowers.

[0013] Since chitosan, which has a function of preventing infection by microorganisms and pathogens, is mixed in the treatment solution, the generation of pathogens on cut flowers can be reliably suppressed.

The freshness-preserving agent of the present invention is prepared by using roses, which are poorly landed, and carnation cut flowers that need to be carefully controlled in a mountain-shaped type. Was. Hydroxyisoxazole 100 times, 500 times, 1000 times, 2000 times. Chitosan is 100 times, 200 times, 300 times, 400 times
Times. And sucrose as a nutrient was tested with a 250-fold mixture. The degree of the freshness-retaining effect of the cut flowers was evaluated by observing the change in the appearance of the cut flowers and evaluating the degree of withering of the petals on the following four scales.

As a typical example, the results of a combination of a mixture of hydroxyisoxazole 500-fold and chitosan 300-fold liquid are shown below.

[0016]

[0017]

From this, it was found that the freshness preserving effect of cut flowers was extremely excellent. The present invention is not limited to these without departing from the gist thereof.

[0019]

Since the present invention is configured as described above, it has the following effects.

According to the present invention, the freshness of cut flowers can be maintained for a long period of time, and the distribution range and the commercial value can be increased. In addition, it was possible to prevent flower producers from causing chemical injury, and to provide an environmental preservation agent and a harmless retaining agent for humans and animals. In addition, long-term freshness retention can be ensured and a low-cost product can be produced, so that a great contribution can be made to the industry, and the effect is great.
