この発明は、植物を生来の形態で保存するための方法に
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a method for preserving plants in their native form.
従来、植物の保存方法としては、押し葉、押し花、ドラ
イフラワ−などのように植物を乾燥させて保存する方法
等が用いられている。しかし、これらの方法によると、
植物は本来のみずみずしさを失っており、また、乾燥し
ていてこわれやすいため、取扱も困難であった。BACKGROUND ART Conventionally, as a method for preserving plants, methods of drying and preserving plants such as pressed leaves, pressed flowers, and dried flowers have been used. However, according to these methods,
The plants had lost their original freshness, and were also difficult to handle because they were dry and fragile.
かかる欠点を解消するため、ドライフラワ−を作製する
際に、植物をグリセリン処理することが行われている。In order to eliminate such drawbacks, plants are treated with glycerin when producing dried flowers.
また、植物にグリセリンとともに色素を含ませることに
よって、植物本来のみずみずしさを保とうとする努力が
払われてきた（特公昭６３−６６８０１号公報等参照）
。Efforts have also been made to preserve the natural freshness of plants by adding pigments to them along with glycerin (see Japanese Patent Publication No. 63-66801, etc.)
.
ところが、上記方法にもまだ欠点があった。たとえば、
日本の冬期における室内のように乾燥した条件下では、
グリセリンが植物外に散逸するなどして保湿効果がな（
なるため、植物の葉が巻いてしまったり、破壊されやす
くなったりするという問題があった。However, the above method still had drawbacks. for example,
Under dry conditions like indoors during the Japanese winter,
Glycerin dissipates outside the plant, resulting in no moisturizing effect (
This causes problems such as the leaves of plants becoming curled or easily destroyed.
このような事情に鑑み、この発明は、乾燥条件下でも、
葉が巻き上がったり破壊されやすくなったりすることな
（、生来の形態で植物を保存することができる処理方法
を提供することを課題とする。In view of these circumstances, the present invention has been developed to
It is an object of the present invention to provide a processing method that can preserve plants in their native form without causing the leaves to curl up or become easily destroyed.
前記課題を解決するため、この発明にかかる植物の保存
処理方法は、生きている植物に硬化性物質の水溶液を吸
い上げさせた後、前記植物内で前記硬化性物質を硬化さ
せて水に不溶化させるようにするものである。In order to solve the above problem, the plant preservation treatment method according to the present invention involves making a living plant absorb an aqueous solution of a curable substance, and then hardening the curable substance within the plant to make it insoluble in water. It is intended to do so.
この発明で用いられる硬化性物質としては、硬化前には
水溶性であるが、硬化後には水に不溶になるものであれ

硬化の度合が高すぎて、植物本来にない固さを与えてし
まうからである。The curable substance used in this invention is not particularly limited as long as it is water-soluble before curing but becomes water-insoluble after curing, but examples include polyethylene glycol methacrylate (PEGMA) etc. In particular, polyethylene glycol methacrylate also has hygroscopicity (moisturizing properties), so it is preferable for maintaining the natural texture such as the freshness of leaves of plants after treatment. Polyethylene glycol methacrylate is available with various molecular weights, but those with an average molecular weight of #250 or more are particularly desirable. If the molecular weight is too small, the number of functional groups per unit amount of plants will increase, so when cured,
This is because the degree of hardening is too high, giving the plant a hardness that is not naturally present.
また、処理性の点からは、平均分子量＃５００以下のも
のを使用するのが望ましい。分子量が大きすぎると、植
物への取り込みが悪くなるからである。Furthermore, from the viewpoint of processability, it is desirable to use one with an average molecular weight of #500 or less. This is because if the molecular weight is too large, uptake into plants will be poor.
この発明にかかる植物の保存処理方法は、主に、前記硬
化性物質の水溶液の植物への吸い上げ工程と前記硬化性
物質の植物内での硬化工程からなるものであり、特に限
定されるわけではないが、たとえば、以下のようにして
行われる。The method for preserving plants according to the present invention mainly consists of a step of sucking up an aqueous solution of the curable substance into the plant, and a step of curing the curable substance within the plant, and is not particularly limited. However, for example, it can be done as follows.
まず、前記硬化性物質の水溶液中に、根等を切断した生
きている植物を切り口の方から浸し、葉からの水の蒸散
を利用した樹液流により植物に硬化性物質の水溶液を吸
い上げさせる。First, a living plant whose roots, etc. have been cut, is immersed in the aqueous solution of the curable substance from the cut end, and the plant is allowed to suck up the aqueous solution of the curable substance by a sap flow that utilizes water transpiration from the leaves.
この際、必要に応じては、硬化性物質の水溶液中に、重

たは複数種混合して用いることができる。前記色素とし
ては、特に限定されないが、セルロースへの吸着が少な
いものが好ましく、たとえば、食品添加剤として使用さ
れることもあるタートラジン、パテントブルー■、ニュ
ーコクシン等が挙げられる。At this time, if necessary, a polymerization initiator, humectant, pigment, etc. may be added in advance to the aqueous solution of the curable substance. The polymerization initiator is not particularly limited, but includes, for example, peroxides such as potassium persulfate. Examples of the humectant include, but are not limited to, glycerin, propylene glycol, polyethylene glycol, and the like, and these can be used alone or in combination. The dye is not particularly limited, but it is preferable to use one that is less adsorbed to cellulose, and examples thereof include tartrazine, patent blue (2), and newcoccin, which are sometimes used as food additives.
前記吸い上げ工程を効率良く行うためには、特に限定さ
れるわけではないが、植物に送風して、前記植物の葉か
らの水の蒸散を促進することが好ましい。In order to efficiently carry out the suction step, it is preferable, although not particularly limited, to blow air onto the plants to promote transpiration of water from the leaves of the plants.
また、同様に吸い上げ工程の効率化を図るには、前記硬
化性物質の水溶液中の水分量が水溶液全体の５０重量％
以上であることが好ましく、７０〜８０重量％であるこ
とがより好ましいが、これに限定されない。Similarly, in order to improve the efficiency of the wicking process, the amount of water in the aqueous solution of the curable substance should be 50% by weight of the entire aqueous solution.
The content is preferably above, and more preferably 70 to 80% by weight, but is not limited thereto.
一方、硬化性物質の濃度は、特に限定されるものではな
（、通用しようとする樹種により異なる。たとえば、カ
シやツバキのような硬質の葉を持つものの場合は、硬化

軟質のものの場合は、それら植物本来の葉の質感（柔ら
かさ）を保つために、硬化性物質の濃度が低いことが好
ましい前記吸い上げ工程は、特に限定されるわけではな
いが、通常は、人工照明下、常温で行われる。On the other hand, the concentration of the hardening substance is not particularly limited (it varies depending on the tree species to be used. For example, in the case of trees with hard leaves such as oaks and camellias, the concentration of the hardening substance is high. However, in the case of soft leaves such as maples and flowering plants, in order to maintain the original texture (softness) of the leaves of these plants, it is preferable that the concentration of the hardening substance is low. This is usually done under artificial lighting and at room temperature, although this is not always the case.
これは、植物に直射日光を当てながら行ったり、温室内
等の高温下で行ったりすると、硬化性物質の硬化反応が
進行しすぎて、保存処理が完了する前に植物が枯死して
しまうことがあるからである。また、前記吸い上げ工程
を暗い条件下で行うと、植物の細胞の活動が不活発にな
り、吸い上げ速度が遅くなるため、好ましくない。If this is done while the plants are exposed to direct sunlight or at high temperatures such as in a greenhouse, the hardening reaction of the hardening substance will progress too much and the plants will wither and die before the preservation process is completed. This is because there is. Furthermore, if the siphoning step is performed under dark conditions, the activity of the plant cells becomes inactive and the siphoning speed becomes slow, which is not preferable.
前記吸い上げ工程の処理時間は、処理条件により異なる
が、おおむね４日程度を要する。この程度の処理時間で
あれば、当初の植物中の水分が、前記硬化性物質の水溶

向上する。The processing time for the suction step varies depending on the processing conditions, but it generally takes about 4 days. This is because, if the treatment time is this long, it can be assumed that the water in the original plant has been replaced by the aqueous solution of the curable substance. Note that, if a trace amount of sugar or a commercially available flower freshness preservative is added to the aqueous solution of the curable substance in advance, the processability will be improved.
このようにして、植物中に前記硬化性物質の水溶液を含

熱により行われる。In this way, after impregnating the plant with the aqueous solution of the curable substance, the curable substance is cured within the plant to make it insoluble in water, thereby obtaining the desired preserved plant. The curing method at this time is not particularly limited, but is usually carried out by heating.

る。The curing temperature must not destroy the natural morphology of the plants to be treated, and varies depending on the type of curable substance used, but for example, if the curable substance is polyethylene glycol methacrylate, a temperature of around 60°C is appropriate. It is. The curing temperature of the curable substance can be set by appropriately selecting the type of polymerization initiator. For example, in order to cure polyethylene glycol methacrylate as a curable substance at around 60°C, potassium persulfate may be used as a polymerization initiator.
[For use] After a living plant absorbs an aqueous solution of a curable substance, the curable substance is cured within the plant to become insoluble in water, and the cured substance is generated and fixed in the plant tissue. In particular, the strength of plant leaves increases, and since the cured product is insoluble in water and does not dissipate outside the plant, even under dry conditions,
This allows plants to be preserved in their native form without the leaves curling up and becoming susceptible to destruction.
