JPS62226901A - Method for making pressed flower of plant by chemical treatment - Google Patents

Abstract

PURPOSE:To obtain pressed flowers of plant which can preserve colors of natural flowers as they are for a long period and prevent fading, by subjecting plants to chemical treatment wherein the plants are directly immersed in a copper ion-containing solution and drying. CONSTITUTION:Plants are directly immersed in a copper ion-containing solution, preferably an acidic solution such as organic acid, organic base, etc., dried or the plants are predried, immersed in the solution or coated with the solution, flowers are adjusted to proper pH in order not to change color in flower pressing and, if necessary, coated with an antioxidant to give pressed flowers (dried flowers) of plant permanently keeping natural colors of plant. An aqueous alcoholic solution, etc., may be used to stop drying or an organic solvent solution may be used. The above-mentioned method is effective for preserving examination results and test materials in botany and the science of agriculture, can raise values as teaching materials (botanical specimen) in schools and also is applicable to production of dried flowers.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is useful for preserving test results and test materials in botany and agriculture, and can increase the value as teaching materials (plant specimens) in schools. It also concerns how to make pressed flowers, which can also be applied to the production of pressed flowers for ornamental purposes.

[Conventional technology]

Traditional pressed flowers are used for two purposes: academically and ornamentally. The most commonly used academic materials are plant leaf markers as teaching materials or leaf specimens for plant taxonomy, but in both cases, the natural shape of the plant has been preserved for a long time. However, the current situation is that little consideration is given to preserving the natural color.

Therefore, the plant specimens kept in schools across the country are mostly faded or discolored.

Contrary to academic studies, pressing flowers for ornamental purposes ignores the original form of the plant and focuses on preserving the flower color, but there is no way to maintain the natural color for a long period of time, Sometimes it is colored.

[Problem that the invention seeks to solve]

Whether it's academic specimen specimens, which place emphasis on shape, or ornamental pressed flowers, which place emphasis on color, there has been a desire for a manufacturing method that allows plants to be preserved for long periods of time. Therefore, the significance of the present invention, which is capable of achieving color fading resistance 1, is extremely significant.

[Failure to solve the problem]

The method of making pressed plant flowers of the present invention is to immerse the plant as it is, that is, as a living organism, in a solution containing copper ions, preferably an acidic solution, and dry it, or to dry the plant in advance. After that, it is characterized in that it is immersed in or coated with the solution described in 1-1 to be collected.

According to the present invention, the natural color of the plant body is permanently maintained. Although it is unclear how the treatment with the copper ion-containing solution in the present invention works, it is thought to be as follows, taking the case where the treatment solution is an acidic solution as an example.

By immersing or coating a plant in an acidic solution containing copper ions, the plant becomes resistant to the solution. Instead, copper ions bind the four pyrroles to form copper chlorophyll, which permanently retains its green color.

Furthermore, the flower color varies from white to yellow, red to blue, depending on pigments such as anthochamps, flavones, and carotenes.

All flower colors are acidic, but when changing from white to yellow, yellow becomes stronger as the acidity becomes closer to alkaline, and when changing from red to blue, red becomes more acidic, and as it approaches alkalinity, it becomes blue, so adjust the pH. By doing so, the color of the flowers can be maintained permanently.

The acidic or alkaline liquid applied to adjust the pH of the plant may be an inorganic acid or inorganic base, but these substances may remain after treatment and damage the plant. Preferably organic acids or organic bases are used. These are usually used in the form of an aqueous solution, but in order to prevent drying, an aqueous alcoholic solution or the like may be used, or a solution using an organic solvent may be used.

This pH adjustment liquid is usually applied after the copper ion-containing solution treatment, but it may be applied before the treatment if necessary.

In the method of the present invention, the collected material may be treated with an antioxidant if necessary. This antioxidant may also contain an ultraviolet absorber that is commonly used in combination.

[Function and Examples]

First example, in the case of lily of the valley using the biological immersion method: For 100 ml of acetone, dichloride
Soak in a copper ion solution containing 0.5 g of copper, 1.0 g of Liponox, and 5.0 g of water for 40 to 60 minutes, then remove and heat with an iron to dry. Make it. Then, place it between newspapers and apply pressure with a weight until it is completely dry.

2nd example, dried body dip coating method For pansies: Place the plant between newspapers and dry for 2 to 48 minutes, then apply acetone 1001, cupric chloride 0.5 g, and Liponox 10.0 g to the stems and leaves. , water 5.0
Apply a solution of copper ions in a proportion of 100 g. Application is performed twice a day continuously for 2 hours.

Apply a 20% solution of tartaric acid to red flowers and white flowers, and apply a 5% solution of triethanolamine to yellow flowers as described above.

〔Effect of the invention〕

It is desirable that plant specimens used in scientific research have the same shape and color as the natural plant, but conventionally, even if the shape is perfect, the color has not been maintained at all. Therefore, the present invention makes it possible for the first time to produce a complete collection of specimens. Furthermore, pressed flowers for ornamental use do not need to be colored with pictures as in the past, and can maintain their natural color for a long period of time.
