JPS63150201A - Preservative for live flower - Google Patents

Abstract

PURPOSE:To obtain a preservative for live flower, effective in suppressing the generation of bacteria and other microorganisms in water in a vase, etc., keeping the water in clean state and prolonging the life of plants having no root, e.g. cut flower or arranged flower, etc., by using alpha-bromocinnamaldehyde as a component. CONSTITUTION:The objective preservative for live flower contains alpha- bromocinnamaldehyde (C6H5-CH=CBr-CHO) as a fungicide. The above compound is hardly soluble in water, however, it exhibits high water-cleaning effect simply by putting into water and is free from phytotoxicity to plants. The above preservative may be properly incorporated with various organic acids or alum, etc., as a pH-modifier, various phosphates, nitrates, sugars, etc., as a fertilizer and KCl, NaCl, etc., as other additives to improve the preservability of the plant. The amount of the fungicidal compound to be added to water is 0.2-1g per 1,000ml of water.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a cut flower or ikebana preservative.

In other words, it is related to an agent that suppresses the growth of bacteria and microorganisms in water in vases and the like (hereinafter referred to as water), keeps the water clean, and preserves rootless plants such as cut flowers and flower arrangements.

Conventional technology Conventionally, as a preservative for rootless plants such as cut flowers and flower arrangements, by setting the pH of the water used to be 3 to 6, which is the same as the body fluid of the plant, it promotes the landing of the plant body, and
The generation of bacteria and microorganisms can be prevented to some extent. (Tokuko Sho 3
8-22358, and as fertilizers, sodium acid birophosphate, sodium hexametaphosphate, potassium metaphosphate, potassium nitrate, sodium nitrate, ammonium nitrate, and sugars such as glucose, fructose, and sucrose are used. (Special Publications No. 46-42563, No. 54, -310
0) Furthermore, as the disinfectant, copper sulfate, iron sulfate, methoxyethylmercuric chloride, dehydroacetic acid, sodium dehydroacetate, sorbic acid, paraoxybenzoic acid alkyl ester, etc. are known. (Special Publications No. 46-42563, No. 44-
12691).

Problems to be Solved by the Present Invention As mentioned above, preservatives for flower arrangements generally consist of pH regulators, fertilizers, and fungicides, but the addition of fungicides is particularly important to prevent water from spoiling. be.

That is, when the water spoils, the plants do not receive water well, shortening their lifespan, and emitting a bad odor, which is unpleasant for the user. There was also the problem that when changing the water in a vase, etc., it became slimy and unpleasant.

As described above, despite the importance of fungicides, there have not been many desirable ones due to safety and phytotoxicity to plants.

Means for Solving the Problems In order to enhance the shelf life of cut flowers and flower arrangements, the present inventor investigated various fungicides and found a fungicide that has excellent water purification ability and has almost no phytotoxicity against plants without roots. They discovered this and completed the present invention.

In other words, from the perspective of making it difficult to cause chemical damage to plants, we conducted experiments focusing on fungicides that are insoluble in water and highly safe for the human body.
, CaH2-CH=CBr-CHo, hereinafter referred to as BCA. ) was found to be highly effective.

That is, BCA is a crystalline powder and is hardly soluble in water, but it has a high water purifying effect just by adding it to water, and has no phytotoxicity to plants, making it very desirable.

In addition, in order to further enhance the shelf life of cut flowers and flower arrangements, these fungicides contain various organic acids and alum as pH regulators, various phosphates, nitrates, sugars, etc. as fertilizers, and chloride as other additives. Potassium, sodium chloride, etc. can be added as appropriate.

Among them, as a pH regulator, as a result of research by the present inventor,
Among various organic acids, ascorbic acid was found to be very preferable as it has no phytotoxic effects on plants.

As a result of experiments, the amount of BCA added to water according to the present invention is as follows:
It is preferable to mix it in an amount of about 0.2 to Ig per 1000 ml of water.

EffectThe experimental results are shown in the table below. The experiment used carnations and chrysanthemums (chrysanthemums were used because their leaves are weak and susceptible to chemical damage).
1 g of disinfectant was added to the water +0QOm+. The temperature in the laboratory was 20-29°C, and the relative humidity was 50-80%.

The table shows the results on the 7th day after the start of storage.

As shown in the table, in addition to BCA, salicylic acid, benzoic acid, sorbic acid, and thioxolone keep the water clear (score 5) even after 7 days of storage, but all of these are blank (no 1 or 2 chrysanthemum leaves compared to
Unfortunately, drug damage was occurring.

Example Next, examples of the present invention will be shown.
