Abstract

PROBLEM TO BE SOLVED: To obtain a life prolongation agent for a cut flower, especially for a cut rose affecting no adverse effect on the environments, capable of exhibiting effect in a small quantity, prepared by using a natural product, not expensive, excellent in safety and free from the troubles of disposal after use. SOLUTION: This life prolongation agent is prepared by using one or more than one kind selected from partial hydrolysates of pectin and chitosan. The pectin is a colloidal polysaccharide widely distributing in plants, mainly contains a straight-chain polymer of D-galacturonic acid and contains acidic polysaccharides. The pectin is used for food, a packaging film, a bacterial medium, etc., and produced by extracting a plant body with a hot solution such as a diluted hydrochloric acid, precipitating a pectin by adding an alcohol to the extracted liquid followed by purification. The chitosan is produced by subjecting chitin massively existing in the carapace of a crab to deacetylation, and used for a biodegradable plastic and a biodegradable insecticide. The concentration of the pectin partial hydrolysate is 1-20ppm and that of the chitosan partial hydrolysate is 10-50ppm, in the life prolongation agent.

The use of various silver salts is because the water-soluble silver salt masks the plant receiving site for ethylene, which is a plant senescence hormone, and contributes to the life extension of cut flowers by inhibiting the plant aging by ethylene. Is being developed. However, the use of silver salts results in the precipitation of black silver, requires careful handling and leaves problems with post-treatment procedures.

Cut flowers are parts of plants that are actively metabolized and follow the same basic senescence phenomena as whole plants. However, since it is separated from the roots of plants, it is considered impossible to externally supplement all the elements necessary to complete the life of flowers, and factors that contribute to the prolongation of the life of cut flowers depending on the type of flower. It is very difficult to develop a substance that optimizes the lifespan of all cut flowers because the type of life-prolonging agent differs depending on the cut flowers.

The active substance in the present invention is considered to be a water-soluble partial hydrolyzate of pectin and chitosan, and the pH of the decomposition liquid is adjusted so that these substances can be collected in a large amount as much as possible.
It is necessary to select the decomposition temperature and the decomposition time. For example,
When pectin is hydrolyzed at pH 1 to 3, the reaction temperature is 70 to 85 ° C., reaction time is 10 to 30 hours, and when it is hydrolyzed at pH 1 or less, reaction temperature is 80 to 90 ° C. and reaction time is several hours. Acidic hydrolysis is performed at high temperature for a long time, and strong acidic hydrolysis is performed at high temperature for a short time. Hydrolysis of chitosan is similar to that of pectin.

The hydrolyzate thus obtained is dissolved in water and used as a cut flower prolonging agent. Since the cut flower life-prolonging agent preferably has a pH of 4 to 6, the obtained hydrolyzate is dissolved in an organic acid such as acetic acid, citric acid, or lactic acid to obtain p.
It is preferably adjusted to H4 to 6 before use. The hydrolyzate solution of chitosan is already on the market as a soil conditioner and a germination and growth promoter {for example, Chuo Kasei Co., Ltd., trade name: Kaguyahime}, so it is convenient to use that solution as a cut flower life-prolonging agent. is there.

The concentration of the water-soluble partial hydrolyzate of pectin and chitosan used as a cut flower prolonging agent is important.
On the contrary, high concentrations reduce the life span of cut flowers, and low concentrations have no effect. The higher the molecular weight of the hydrolyzate, the lower the use concentration may be, and the effective concentration differs depending on the pectin and chitosan raw materials. Generally, pectin is stronger, and pectin is 0.5 to 50 ppm, preferably 1 to 20 pp
