Description

本発明は、植物活性化剤及び肥料組成物、並びに病害防除方法及び植物生育方法に関する。 The present invention relates to plant activators and fertilizer compositions, and methods of disease control and plant growth.

従来より、カルシウム源や多孔質体として卵殻を配合した肥料が広く知られている。例えば、特許文献1には家畜***物等に乾燥卵殻を混合した熟成させた粒状化肥料が報告されている。また、特許文献2には卵殻と米糠の混合物をペレット状に加工した肥料が開示されている。また、特許文献3には、食酢もろみ粕と卵殻と珪藻土を含む肥料が開示されている。 Conventionally, fertilizers containing eggshells as a calcium source and porous material have been widely known. For example, Patent Literature 1 reports a matured granulated fertilizer obtained by mixing dried eggshells with livestock excrement or the like. Further, Patent Document 2 discloses a fertilizer obtained by processing a mixture of eggshell and rice bran into pellets. Moreover, Patent Document 3 discloses a fertilizer containing vinegar mash, eggshells and diatomaceous earth.

卵殻は、糖蛋白質からなる卵殻膜や卵白を含み、これらが腐敗して悪臭を発生させるため、通常、卵殻に付着したタンパク質成分(卵殻膜や卵白)は除去して使用されている。例えば、特許文献4には、卵殻内から卵白を洗浄除去したのちに、卵殻膜付の卵殻を炭酸水溶液に浸漬して卵殻から卵殻膜を分離し夫々を回収する卵殻と卵殻膜との分離回収方法が報告されている。回収した卵殻は肥料等の原料とされ、卵殻膜は例えば、化粧料等の原料等として利用されている。 Eggshells contain eggshell membranes and albumen composed of glycoproteins, and these decompose to produce offensive odors. Therefore, protein components adhering to eggshells (eggshell membranes and albumen) are usually removed before use. For example, in Patent Document 4, after washing and removing the egg white from the inside of the eggshell, the eggshell with the eggshell membrane is immersed in a carbonated water solution to separate the eggshell membrane from the eggshell and recover the eggshell and the eggshell membrane separately. A method is reported. The collected eggshells are used as raw materials for fertilizers and the like, and eggshell membranes are used as raw materials for cosmetics and the like.

上記の通り、卵殻を配合した肥料が広く知られているが、卵殻膜は、肥料としてほとんど使用されていない。その理由の一つとして、卵殻膜は比較的分解されにくい蛋白質であり、そのままの状態では土壌にいれても生分解されにくいことが挙げられる。また、卵白や卵黄においても、肥料として利用することは一般的に行われていない。 As described above, eggshell-containing fertilizers are widely known, but eggshell membranes are rarely used as fertilizers. One of the reasons for this is that the eggshell membrane is a protein that is relatively difficult to decompose, and it is difficult to biodegrade even if it is placed in soil as it is. Also, egg whites and egg yolks are not generally used as fertilizers.

かかる状況下、本発明の目的は、卵由来成分を原料とした植物活性化剤及びこれを配合した肥料組成物、並びにこれらを使用した病害防除方法及び植物生育方法を提供することである。 Under such circumstances, an object of the present invention is to provide a plant activator using an egg-derived component as a raw material, a fertilizer composition containing the same, and a disease control method and a plant growth method using these.

The present invention relates to a plant activator containing an egg-derived hydrolyzate (hereinafter referred to as "the plant activator of the present invention"). The plant activator of the present invention has a plant activating action (plant growth promoting action and disease resistance action) resulting from the egg-derived hydrolyzate, which is an active ingredient, when absorbed by target plants.

本明細書において「植物活性化作用」は、植物生長促進作用又は病害抵抗作用を意味する。本発明の植物活性化剤は植物生長促進作用及び病害抵抗作用の少なくとも一つの作用を有し、両方の作用を有していることがより好ましい。 As used herein, "plant activating action" means plant growth promoting action or disease resistance action. The plant activator of the present invention has at least one action of plant growth promotion action and disease resistance action, and more preferably has both actions.

「植物生長促進作用」は、発芽後の植物の生長を促進させる作用を意味し、茎の伸長・肥大、根の伸長・肥大及び葉の生長、果実の発生・肥大等を含む。具体的には、植物の生長促進、発根性の向上、花や葉への発色性の向上などが含まれる。
「病害抵抗作用」は、植物の病気の予防、抑制、改善の少なくともひとつの作用を意味する。
“Plant growth promoting action” means the action of promoting the growth of a plant after germination, and includes stem elongation/enlargement, root elongation/enlargement, leaf growth, fruit development/enlargement, and the like. Specifically, it includes promotion of plant growth, improvement of rooting, and improvement of coloring of flowers and leaves.
"Disease-resistant action" means at least one action of preventing, suppressing, or ameliorating plant diseases.

本発明の植物活性化剤は、含有する卵由来加水分解物に起因して植物生長促進作用、病害抵抗作用に対して効果を奏するため、「植物生長促進用」や「病害抵抗用」の植物活性化剤として用いることができる。 The plant activator of the present invention exerts an effect on plant growth promotion and disease resistance due to the egg-derived hydrolyzate contained, so it is useful for plant growth promotion and disease resistance. It can be used as an activator.

本明細書において「卵由来加水分解物」は、卵殻膜加水分解物、卵白加水分解物及び卵黄加水分解物を総称したものであり、卵殻膜、卵白又は卵黄のタンパク質を水に可溶化するまで加水分解した加水分解物を意味する。
なお、本明細書において、「水に可溶化する」とは、卵由来加水分解物が溶解している状態だけでなく、自然沈降せずに分散している状態を含むものとする。
As used herein, "egg-derived hydrolyzate" is a generic term for eggshell membrane hydrolyzate, egg white hydrolyzate and egg yolk hydrolyzate. Hydrolyzed hydrolyzate is meant.
In the present specification, "to be solubilized in water" includes not only the state in which the egg-derived hydrolyzate is dissolved, but also the state in which it is dispersed without spontaneous sedimentation.

本明細書において「卵殻膜加水分解物」は、卵殻膜に含まれる成分の加水分解物を意味する。卵殻膜は鳥類(特には鶏)の卵殻の内側にある繊維質の薄膜であり、外卵殻膜及び内卵殻膜の二層の網目状構造からなる。卵殻膜の水分を除く主成分はタンパク質であるが、その他にも脂質や糖質等を含む。なお、卵殻膜のタンパク質は約20種類のアミノ酸で構成され、特にシスチンを多く含む。卵殻膜はさらにコラーゲンとヒアルロン酸を含むという特徴がある。 As used herein, "eggshell membrane hydrolyzate" means a hydrolyzate of components contained in eggshell membranes. The eggshell membrane is a fibrous thin film inside the eggshell of birds (especially chickens), and consists of a two-layer network structure of outer and inner eggshell membranes. The main component of the eggshell membrane, excluding water, is protein, but it also contains lipids, carbohydrates, and the like. Eggshell membrane proteins are composed of about 20 kinds of amino acids, and contain a particularly large amount of cystine. The eggshell membrane is also characterized by containing collagen and hyaluronic acid.

卵殻膜のタンパク質は、通常、加水分解(酸、アルカリ、酵素等)を行ったとしても分解されにくく、完全に遊離アミノ酸まで分離されにくい。後述する実施例に示すように、本発明の植物活性化剤に含有される卵殻膜加水分解物は、加水分解ペプチドを含有する。 Eggshell membrane proteins are generally not easily decomposed even by hydrolysis (acid, alkali, enzyme, etc.) and are difficult to completely separate into free amino acids. As shown in the examples below, the eggshell membrane hydrolyzate contained in the plant activator of the present invention contains a hydrolyzed peptide.

なお、本明細書において、用語「ペプチド」は、アミド結合(ペプチド結合)によって連結された2つ以上のアミノ酸から構成される分子のうち、重量平均分子量(MW)が20000以下の分子を意味するものとする。したがって、ジペプチド、トリペプチド、オリゴペプチド、ポリペプチド、または2つ以上のアミノ酸の鎖(複数可)を指すために使用される他の用語は、当該「ペプチド」の定義に含まれるものとする。なお、以下において、単に「分子量」と記載された場合は「重量平均分子量」を意味するものとする。 As used herein, the term "peptide" means a molecule having a weight average molecular weight (MW) of 20000 or less among molecules composed of two or more amino acids linked by an amide bond (peptide bond). shall be Thus, dipeptides, tripeptides, oligopeptides, polypeptides, or other terms used to refer to chain(s) of two or more amino acids are included in the definition of "peptide". In the following description, the term "molecular weight" simply means "weight average molecular weight".

本明細書において「卵白加水分解物」は、卵白に含まれる成分の加水分解物を意味する。卵白は鳥類(特には鶏)の卵黄膜と卵殻膜の間にあるゾル状の物質であり、水分を除く主成分はタンパク質であるが、その他にも脂質や糖質等を含む。なお、卵白のタンパク質の主成分はアルブミンであり、上記卵殻膜タンパク質とは異なる。 As used herein, "egg white hydrolyzate" means a hydrolyzate of components contained in egg white. Egg white is a sol-like substance between the vitelline membrane and the eggshell membrane of birds (especially chickens). The main protein component of egg white is albumin, which is different from the eggshell membrane protein.

本明細書において「卵黄加水分解物」は、卵黄に含まれる成分の加水分解物を意味する。卵黄は鳥類(特には鶏)の卵白に内包された卵細胞に貯蔵される栄養物質である。卵黄は脂質(中性脂質、リン脂質及びコレステロール)を主成分とし、その他にもタンパク質や糖質等を含む。 As used herein, "egg yolk hydrolyzate" means a hydrolyzate of components contained in egg yolk. Egg yolk is a nutritional substance stored in the egg cell enclosed in the egg white of birds (especially chickens). Egg yolk is mainly composed of lipids (neutral lipids, phospholipids and cholesterol), and also contains proteins, carbohydrates and the like.

加水分解処理に供される卵殻膜、卵白、卵黄の形態は、特に限定されず、例えば、乾燥状態や湿潤状態のものを使用できる。 The forms of the eggshell membrane, albumen, and yolk to be hydrolyzed are not particularly limited, and for example, those in a dry state or a wet state can be used.

本発明の植物活性化剤は、植物活性化作用を有する卵由来加水分解物を有効成分として含有する。すなわち、本発明の植物活性化剤は、植物活性化作用を有する限り、卵殻膜加水分解物、卵白加水分解物及び卵黄加水分解物を含有することができ、これらの加水分解物の配合割合は、本発明の植物活性化剤が植物活性化効果を奏する範囲で適宜選択することができる。 The plant activator of the present invention contains an egg-derived hydrolyzate having a plant activating action as an active ingredient. That is, the plant activator of the present invention can contain an eggshell membrane hydrolyzate, an egg white hydrolyzate and an egg yolk hydrolyzate as long as it has a plant activating action. , can be appropriately selected within the range in which the plant activator of the present invention exhibits a plant activation effect.

また、本発明の植物活性化剤は、植物活性化作用を有する限り様々な分子量の卵由来加水分解物を含んでいてもよい。
また、所望の分子量分布に調整してもよい。例えば、分子量が大きく非水溶性の卵由来加水分解物を得たのちに、さらなる加水分解によって植物活性化作用を有する加水分解物(加水分解ペプチド)として水に可溶化したり、様々な分子量の加水分解物を含む溶液から遠心分離や分離膜等を使用して所望の分子量分布のものを回収したりして使用してもよい。
In addition, the plant activator of the present invention may contain egg-derived hydrolysates of various molecular weights as long as they have a plant activating effect.
Moreover, you may adjust to desired molecular weight distribution. For example, after obtaining a water-insoluble egg-derived hydrolyzate with a large molecular weight, it is further hydrolyzed to make it solubilized in water as a hydrolyzate (hydrolyzed peptide) having a plant-activating effect. A compound having a desired molecular weight distribution may be recovered from a solution containing a hydrolyzate using centrifugation, a separation membrane, or the like.

卵由来加水分解物は、重量平均分子量の上限及び下限は、植物活性化作用を有する範囲で適宜決定される。なお、重量平均分子量は、サイズ排除クロマトグラフィーで得られる分子量分布から求めることができる。 The upper and lower limits of the weight-average molecular weight of the egg-derived hydrolyzate are appropriately determined within a range in which the plant-activating action is exhibited. The weight average molecular weight can be determined from the molecular weight distribution obtained by size exclusion chromatography.

本発明の植物活性化剤は、卵由来加水分解物の中でも、特に卵殻膜加水分解物を含有することが好ましい。卵殻膜加水分解物を含有させることによって、植物活性化作用である植物生長促進作用及び病害抵抗作用の両方に対して優れた効果を発揮することができる。 The plant activator of the present invention preferably contains an eggshell membrane hydrolyzate among egg-derived hydrolysates. By containing the eggshell membrane hydrolyzate, excellent effects can be exhibited with respect to both plant growth promoting action and disease resistance action, which are plant activating actions.

卵殻膜加水分解物が優れた植物活性化作用(植物生長促進作用及び病害抵抗作用の両方)を有する理由については不明な点もあるが、卵殻膜のタンパク質は、上述の通り、約20種類のアミノ酸で構成され、特にシスチンを多く含んでいる点や、実施例で示されるように卵殻膜加水分解物には卵殻膜由来のペプチドを多く含んでいることから、当該ペプチドが植物活性化作用に優れているものと推測される。 Although the reason why the eggshell membrane hydrolyzate has an excellent plant activating effect (both plant growth promoting effect and disease resistance effect) is unclear, eggshell membrane proteins contain about 20 kinds of proteins as described above. Since it is composed of amino acids and contains a large amount of cystine in particular, and as shown in Examples, the eggshell membrane hydrolyzate contains a large amount of peptides derived from eggshell membranes, the peptide has a plant activating effect. presumed to be excellent.

また、卵殻膜加水分解物は化粧品等の原料としても使用される成分であるため、本発明の植物活性化剤が皮膚に付着した場合に皮膚を保護する作用が期待される。 In addition, since the eggshell membrane hydrolyzate is a component used as a raw material for cosmetics and the like, it is expected that the plant activator of the present invention will protect the skin when it adheres to the skin.

このような卵殻膜加水分解物に由来する作用を得るためには、卵殻膜加水分解物の割合は、卵由来加水分解物100重量%としたときに、10重量%以上であり、好ましくは30重量%以上であり、より好ましくは50重量%以上であり、さらに好ましくは80重量%以上である。また、卵由来加水分解物が卵殻膜加水分解物のみ(100重量%)であってもよい。 In order to obtain such effects derived from the eggshell membrane hydrolyzate, the ratio of the eggshell membrane hydrolyzate is 10% by weight or more, preferably 30% by weight, based on 100% by weight of the egg-derived hydrolyzate. % by weight or more, more preferably 50% by weight or more, and even more preferably 80% by weight or more. Further, the egg-derived hydrolyzate may be only the eggshell membrane hydrolyzate (100% by weight).

一方、卵殻膜加水分解物の割合が多くなりすぎると流動性が低下する場合がある。そのため、流動性を高める点では、卵由来加水分解物は、卵殻膜加水分解物と卵白加水分解物の混合物としてもよい。その配合割合は、卵殻膜加水分解物と卵白加水分解物の合計を100重量%としたときに、卵白加水分解物が10重量%~50重量%である。 On the other hand, if the proportion of the eggshell membrane hydrolyzate is too high, the fluidity may decrease. Therefore, the egg-derived hydrolyzate may be a mixture of an eggshell membrane hydrolyzate and an egg white hydrolyzate from the viewpoint of enhancing fluidity. The mixing ratio is 10% to 50% by weight of the egg white hydrolyzate when the total of the eggshell membrane hydrolyzate and the egg white hydrolyzate is 100% by weight.

本発明の植物活性化剤は、通常、液状組成物(卵由来加水分解物が可溶化した状態)として施用されるが、溶媒を留去させて固体組成物として施用することもできる。固体組成物の場合は、卵由来加水分解物を乾燥させて粉末や顆粒などの形状として施用することができる。
なお、本明細書において、「液状」とは、常温(10~25℃、以下同様)において、組成物が固化しておらず、流動性のある状態を意味する。
The plant activator of the present invention is usually applied as a liquid composition (in which the egg-derived hydrolyzate is solubilized), but it can also be applied as a solid composition after distilling off the solvent. For solid compositions, the egg-derived hydrolyzate can be dried and applied in the form of powder, granules, or the like.
In the present specification, the term “liquid” means that the composition is not solidified and has fluidity at room temperature (10 to 25° C., hereinafter the same).

本発明の植物活性化剤が液状組成物である場合、卵由来加水分解物は、溶媒に溶解又は分散されている。また、凝集や沈殿の発生した場合でもこれを再度撹拌することにより、本発明の植物活性化剤を液状組成物として施用することができる。 When the plant activator of the present invention is a liquid composition, the egg-derived hydrolyzate is dissolved or dispersed in a solvent. Further, even when aggregation or precipitation occurs, the plant activator of the present invention can be applied as a liquid composition by stirring again.

溶媒としては、通常、水のみが用いられるが、卵由来加水分解物の溶解や分散を阻害せず、施用対象となる植物に悪影響を及ぼさない範囲で水に相溶性の溶媒であれば、水に混合して用いることもできる。溶媒における水の割合は、80重量%以上(100重量%含む)である。水以外の溶媒としては、エタノールなど低級アルコールが挙げられる。 As a solvent, only water is usually used, but any water-compatible solvent can be used as long as it does not inhibit the dissolution or dispersion of the egg-derived hydrolyzate and does not adversely affect the plant to be applied. It can also be used by mixing with The proportion of water in the solvent is 80% by weight or more (including 100% by weight). Solvents other than water include lower alcohols such as ethanol.

また、卵由来加水分解物の溶解や分散を阻害せず、施用対象となる植物に悪影響を及ぼさないものであれば、本発明の植物活性化剤は、溶媒以外にも任意の成分を含んでいてもよい。このような成分として、例えば、公知の分散剤、pH調整剤等が挙げられる。 In addition, the plant activator of the present invention may contain any component other than the solvent as long as it does not inhibit the dissolution or dispersion of the egg-derived hydrolyzate and does not adversely affect the plant to which it is applied.

FIG. 4 shows a graph of the growth survey of each cultivated vegetable.
As shown in FIG. 4( a ), the growth of turnips was evaluated by comparing Samples 2, 3 and 4 to which the eggshell membrane hydrolyzate was added and Sample 1 (no eggshell membrane hydrolyzate was added). showed a slight upward trend, but a marked increase in plant height was observed.
As shown in FIG. 4(b), when comparing samples 2, 3 and 4 to which eggshell membrane hydrolyzate was added and sample 1 (no eggshell membrane hydrolyzate added), the growth of bok choy showed leaf length, plant height, An increasing tendency was observed for both leaf width.
As shown in Fig. 4(c), when comparing samples 2, 3 and 4 to which eggshell membrane hydrolyzate was added and sample 1 (no eggshell membrane hydrolyzate added), the plant height and leaf width of lettuce were similar. However, an increasing tendency was observed for leaf length.
As described above, although the growth status of each item differs depending on the cultivated vegetables, the plots sprayed with Samples 2, 3, and 4 are better for Sample 1, to which the eggshell membrane hydrolyzate is not added, in any of the cultivated vegetables. Compared to the plots sprayed with

試験例4(新鮮物収穫量)
カブ(品種:絹はだ、会社名:株式会社ウタネ)、青梗菜(品種:武帝、会社名:株式会社サカタのタネ)については、種蒔28日目から35日目までの8日間、肥料組成物(試料1~5)を1日6回散布した以外は上記(試験例3)と同じ方法で栽培し、種蒔から35日目の収穫時における新鮮物重量を測定した。測定結果を「新鮮物収穫量」として算出した。
なお、「新鮮物収穫量」とは、収穫した栽培野菜の重量のことを意味する。カブは地下部と地上部(葉)の総重量を測定したもの、青梗菜は地下部(根)を取り除いた地上部のみの重量を測定したものを「新鮮物収穫量」とした。
Test Example 4 (Fresh product yield)
For turnips (variety: Kinuhada, company name: Utane Co., Ltd.) and bok choy (variety: Mutei, company name: Sakata Seed Co., Ltd.), fertilizer composition was applied for 8 days from the 28th day to the 35th day of seeding The plants (Samples 1 to 5) were cultivated in the same manner as described above (Test Example 3) except that the plants (Samples 1 to 5) were sprayed 6 times a day, and the fresh plant weight was measured at the time of harvest on the 35th day after seeding. The measurement results were calculated as "fresh product yield".
In addition, the "fresh product yield" means the weight of the harvested cultivated vegetables. For turnips, the total weight of the underground and above-ground parts (leaves) was measured, and for bok choy, the weight of only the above-ground parts, with the underground parts (roots) removed, was measured, and this was used as the "fresh yield".

図5に各栽培野菜の新鮮物収穫量のグラフを示す。卵殻膜加水分解物を添加した試料2、3及び4を散布したカブ及び青梗菜は、卵殻膜加水分解物を添加していない試料1を散布したカブ及び青梗菜と比較して、新鮮物収穫量が多いことが認められた。 FIG. 5 shows a graph of the fresh yield of each cultivated vegetable. Turnip and bok choy sprayed with Samples 2, 3 and 4 to which the eggshell membrane hydrolyzate was added were compared to turnips and bok choy sprayed with Sample 1 without the eggshell membrane hydrolyzate added, and the fresh product yield was higher. A large amount was found.

<植物活性化剤B>
植物活性化剤Aにおいて、卵殻膜粉末225g及び乾燥卵白粉末75gを混合した以外は、同様の製造方法で植物活性化剤B(原液)を得た。なお、卵殻膜粉末及び卵白粉末の合計に対する卵白粉末の割合は、25重量%である。
<植物活性化剤C>
植物活性化剤Aにおいて、卵殻膜粉末150g及び乾燥卵白粉末150gを混合した以外は、同様の製造方法で植物活性化剤C(原液)を得た。なお、卵殻膜粉末及び卵白粉末の合計に対する卵白粉末の割合は、50重量%である。
<Plant activator A>
Plant activator A (undiluted solution) was obtained in the same manner as in Production 2 of egg-derived hydrolyzate, except that 300 g of eggshell membrane powder was added to 1200 g of water, and 3 g of protease was added to each. The ratio of egg white powder to the total of eggshell membrane powder and egg white powder is 0% by weight.
<Plant Activator B>
Plant activator B (undiluted solution) was obtained in the same production method as in plant activator A, except that 225 g of eggshell membrane powder and 75 g of dried egg white powder were mixed. The ratio of egg white powder to the total of eggshell membrane powder and egg white powder was 25% by weight.
<Plant activator C>
Plant activator C (undiluted solution) was obtained in the same production method as in plant activator A, except that 150 g of eggshell membrane powder and 150 g of dried egg white powder were mixed. The ratio of egg white powder to the total of eggshell membrane powder and egg white powder was 50% by weight.

図9に示すように、酵素処理による植物活性化剤F(EH-ESM1)及び還元剤共存下で酵素処理による加水分解を促進させた植物活性化剤G(EH-ESM2)と、アルカリ処理による植物活性化剤H(AH-ESM)とは異なる分子量分布を示した。植物活性化剤F及び植物活性化剤G(酵素処理)のメインピークはMW556に相当し、植物活性化剤H(アルカリ処理)のメインピークはMW6511に相当した。
分子量検量曲線から算出されるクロマトグラムのピークトップ分子量は、植物活性化剤F及び植物活性化剤G(酵素処理)では各々333及び509、植物活性化剤H(アルカリ処理)では7222となった。
As shown in FIG. 9, plant activator F (EH-ESM1) by enzymatic treatment and plant activator G (EH-ESM2) that accelerated hydrolysis by enzymatic treatment in the presence of a reducing agent, and alkali treatment It showed a different molecular weight distribution than plant activator H (AH-ESM).

The peak top molecular weight of the chromatogram calculated from the molecular weight calibration curve was 333 and 509 for plant activator F and plant activator G (enzyme treatment), respectively, and 7222 for plant activator H (alkali treatment). .

また、表5に示すように、植物活性化剤F及び植物活性化剤G(酵素処理)の重量平均分子量は、2000~2200程度、植物活性化剤H(アルカリ処理)の重量平均分子量は、3400程度であることから、卵殻膜を構成するアミノ酸1分子(例えば、ピロリン(MW115)、システイン(MW121)、シスチン(MW240)等)と比較してはるかに大きい。
すなわち、異なる製法で製造された植物活性化剤F~Hはいずれも遊離アミノ酸が主体であるのではなく、ペプチドが主体であることが認められた。
