Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut flower prolonging agent containing an organic acid aluminum as an active ingredient.

[0002]

2. Description of the Related Art It is known that cut flowers become wilted by the loss of water absorption from leaves and flowers due to a decrease in water absorption due to being cut off from roots and the growth of bacteria in live water. Has been. In order to improve this, as conventional cut flower life-prolonging agents, surfactants for promoting water absorption, aluminum sulfate, alum, fungicides (8-hydroxyquinoline, quaternary ammonium, etc.), etc. are known. Is compounded in. However, it is said that these conventional agents for prolonging the life of cut flowers bring about an effect on plants as well as phytotoxicity (when added to live water at a concentration necessary to exert the effect, it causes yellowing of leaves, darkening of petals, leaf loss, etc.). There was a flaw.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a compound which has a small phytotoxicity and exhibits a life-prolonging effect on cut flowers by retaining the water content of cut flowers at a low concentration.

[0004]

As a result of intensive studies, the present inventors have found that a specific organic aluminum salt can achieve the above-mentioned object, and completed the present invention. That is,
The present invention is a life-prolonging agent for cut flowers, which contains, as an active ingredient, one or more kinds of aluminum of an organic acid. In the present invention,
The organic acid aluminum is a salt of an organic acid naturally present in the plant and aluminum, and as the organic acid naturally present in the plant, malic acid, citric acid, tartaric acid,
Lactic acid, oxalic acid, rutin, etc. are mentioned. Of these, those having high water solubility are preferable.

The cut flower prolonging agent of the present invention is in the form of a solid agent (eg, powder, tablet, etc.) or liquid agent. Here, for example, when the dosage form is a liquid, it can be prepared by dissolving it in water. At this time, nutrient sources such as glucose, sucrose and amino acids, bactericides such as 8-hydroxyquinoline and quaternary ammonium salts, and plant growth regulators such as gibberellin and benzyladenine can be added. The concentration of the organic acid aluminum in the formulation of each of the above dosage forms ranges from the concentration at which the organic acid aluminum begins to exert its effect to the maximum concentration at which the chemical damage does not occur. The specific value varies depending on the conditions such as the type of cut flowers, but generally 0.1 mM-5 mM
Is. The cut flowers subject to the cut flower life-prolonging agent of the present invention are not particularly limited, but examples include roses, carnations, chrysanthemums, dahlia, freesia, sweet pea, gypsophila, delphinium, statice, matsusou, stock, cosmos, anemone. , Poppies, orchids, etc.

[0006]

Industrial Applicability According to the present invention, it has become possible to provide an excellent agent for prolonging the life of cut flowers with less phytotoxicity, which can be used for prolonging the life of cut flowers.

[0007]

EXAMPLES The present invention will be described in more detail below with reference to examples and test examples. Example 1 A liquid agent was prepared by dissolving and mixing 0.1 g of aluminum lactate, 4 g of glucose, and 0.2 g of formalin in 500 ml of tap water (aluminum lactate concentration is about 0.7 m.
M). Example 2 0.05 g of aluminum lactate, 4 g of glucose, and 0.2 g of formalin were dissolved and mixed in 500 ml of tap water to prepare a liquid agent (aluminum lactate concentration was about 0.3 m.
M). Example 3 0.2 g of aluminum lactate, 4 g of glucose, and 0.2 g of formalin were dissolved and mixed in 500 ml of tap water to prepare a liquid agent (aluminum lactate concentration was about 1.4 m.
M). Example 4 0.5 g of aluminum malate, 5 g of glucose, and 100 mg of 8-hydroxyquinoline sulfate were added to 50 parts of tap water.
A solution was prepared by dissolving and mixing in 0 ml.

Test Example 1 Cut flower of chrysanthemum chrysanthemum The life expectancy of cut flower of chrysanthemum “Seiun” was used for the test. The number of days from the time when the cut flowers were put into the test solution shown in Table 1 until the wilt and leaf phytotoxicity (yellowing and browning) were observed was counted. For each test solution, four cut flowers were used for the test. The results are shown in Table 1.
Shown in.

[0009]

[Table 1]

Note: -indicates that no phytotoxicity was observed. Comparative Test Solution 1 was prepared by dissolving and mixing 0.35 g of alum, 4 g of glucose and 0.2 g of formalin in 500 ml of tap water (alum). Concentration about 1.4m
M). The comparative test solution 2 was prepared by dissolving and mixing 0.17 g of alum, 4 g of glucose and 0.2 g of formalin in 500 ml of tap water (alum concentration of about 0.7 m).
M). Comparative test solution 3 was prepared by dissolving and mixing 0.08 g of alum, 4 g of glucose and 0.2 g of formalin in 500 ml of tap water (alum concentration of about 0.3 m).
M). The comparative test liquid 4 consists of 500 ml of tap water. In each case, when the test liquid was insufficient due to water absorption of cut flowers, each test liquid was replenished.

Test Example 2 Effect of prolonging the life of cut flowers of roses Cut flowers of rose "Roterose" were used for the test. Put the cut flowers in the test solution shown in Table 2, then wilt or bend.
The number of days until Neck (neck sagging) was observed was counted. For each test solution, four cut flowers were used for the test.
The results are shown in Table 2.

[0012]

[Table 2]

Note) -indicates that Bent Neck was not found. The formulations and preparation methods of the comparative test solutions 1 to 4 are the same as those shown in Test Example 1.
