Description
本発明は、切り花を新鮮な状態で長期間保持することができる、切り花延命剤に関するものである。 The present invention relates to a cut flower life-prolonging agent capable of keeping cut flowers fresh for a long period of time.
切り花は、生産者により作付け地で切り取られて市場に出荷された後、消費者が購入するまで数日を要す。この間に花の鮮度が落ちるため、種々の切り花の延命方法が開発されてきた。 Cut flowers are cut by producers at the planting site and shipped to the market, after which it takes several days for consumers to purchase them. During this period, the freshness of the flowers declines, so various methods for prolonging the life of cut flowers have been developed.
切り花の延命方法には従来から様々な手法が採用されているが、主として植物ホルモンの抑制・除去、界面活性剤の添加による水の吸い上げ力の向上、糖等の栄養剤の添加、殺菌剤添加による腐敗防止、pHの調整等の方法が知られており、これらの方法を組み合わせて使用されている。(特許文献1、2、3) Various methods have been used to prolong the life of cut flowers, but mainly the suppression and removal of plant hormones, the improvement of water absorption by adding surfactants, the addition of nutrients such as sugar, and the addition of bactericides. Methods such as prevention of putrefaction and adjustment of pH are known, and these methods are used in combination. (Patent Documents 1, 2, 3)
これらの延命処理の中で、添加される殺菌剤は一般に、第四級アンモニウム塩が使用されており、 糖類と併用することで切り花の延命効果が高くなることが示されている。(特許文献4、5)しかしながら糖類と併用することで水が腐敗し、花の水の吸い上げが悪くなるという問題があった。 In these life-prolonging treatments, quaternary ammonium salts are generally used as the fungicide to be added, and it has been shown that the life-prolonging effect of cut flowers is enhanced when used in combination with saccharides. (Patent Documents 4 and 5) However, when used in combination with sugars, there is a problem that water rots and the uptake of flower water becomes poor.
本発明は上記の事情を解決し、切り花を新鮮な状態に長期間保持することができる切り花延命剤を提供することが目的である。 An object of the present invention is to solve the above-mentioned circumstances and to provide a cut flower life-prolonging agent capable of keeping cut flowers in a fresh state for a long period of time.
本発明者は、上記課題を解決するために鋭意研究を行った結果、以下の特定の構成が優れた切り花延命効果を得られることを見出し、本発明を完成させた。 As a result of diligent research to solve the above problems, the present inventor has found that the following specific configuration can obtain an excellent cut flower life-prolonging effect, and has completed the present invention.
すなわち本発明は、
(1)一般式1
(2)上記(1)に記載の切り花延命剤を切り花またはフラワーアレンジメントに作用させることを特徴とする切り花延命方法。
That is, the present invention
(1) General formula 1
(2) A method for prolonging the life of cut flowers, which comprises allowing the cut flower life-prolonging agent according to (1) above to act on a cut flower or a flower arrangement.
本発明の切り花延命剤を用いることにより、花弁や葉のしおれ、茎の黄変、ベントネックを遅くし、新鮮な状態で長期間保持できることにより鑑賞期間を長くすることが可能となる。なおベントネックとは花の茎の部分が折れ曲がってくる現象である。 By using the cut flower life-prolonging agent of the present invention, it is possible to delay the wilting of petals and leaves, yellowing of stems, and bent neck, and to keep the flowers fresh for a long period of time, so that the viewing period can be extended. Bent neck is a phenomenon in which the stem of a flower bends.
本発明の切り花延命剤は
一般式1
本発明の切り花延命剤中に含有するDDABCの濃度範囲は0.0001〜50重量%の範囲であることが好ましく、0.0005〜25重量%の範囲がより好ましく、さらに0.0005〜0.005重量%が好ましい。0.0001重量%以下の濃度では、切り花延命剤の効果が十分ではなく、50重量%以上の濃度では、切り花に薬害が発生する場合がある。 The concentration range of DDABC contained in the cut flower life-prolonging agent of the present invention is preferably in the range of 0.0001 to 50% by weight, more preferably in the range of 0.0005 to 25% by weight, and further preferably in the range of 0.0005 to 0% by weight. 005% by weight is preferable. At a concentration of 0.0001% by weight or less, the effect of the cut flower life-prolonging agent is not sufficient, and at a concentration of 50% by weight or more, phytotoxicity may occur on the cut flowers.
糖類を配合する場合には、糖類としてブドウ糖、ショ糖、果糖、オリゴ糖等を用いることができ、これらのうちの1種または2種以上を用いることができる。糖類は植物に対する栄養分として作用するものであり、切り花のつぼみを開花させる際には必要に応じて使用しても良い。 When saccharides are blended, glucose, sucrose, fructose, oligosaccharides and the like can be used as the saccharides, and one or more of these can be used. Sugars act as nutrients for plants and may be used as needed when flowering cut flower buds.
本発明については、本発明の効果に影響を与えない範囲で他の添加剤を配合することも可能である。例えば、水溶性ミネラル、有機酸、界面活性剤、植物ホルモン、次亜塩素酸ナトリウム、硫酸銀、硫酸アルミニウム、pH調整剤、キレート剤等の添加成分を配合することも可能である。 Regarding the present invention, it is also possible to add other additives as long as the effects of the present invention are not affected. For example, it is also possible to add additional components such as water-soluble minerals, organic acids, surfactants, plant hormones, sodium hypochlorite, silver sulfate, aluminum sulfate, pH adjusters, and chelating agents.
また本発明の対象とする花の種類に関して特に限定はされるものではなく、バラ、ガーベラ、カーネーション、キク、チューリップ、スターチス、ユリ、ダリア、スイートピー、デルフィニウム、カスミソウ、洋ラン等を具体的に挙げることができる。 The type of flower targeted by the present invention is not particularly limited, and specific examples thereof include rose, gerbera, carnation, chrysanthemum, tulip, statice, lily, dahlia, sweet pea, Delphinium, gypsophila, and orchid. be able to.
本発明の切り花延命剤を切り花またはフラワーアレンジメントに作用させることができる。切り花に作用させるとは、例えば、切り花用の容器に本発明の切り花延命剤を注ぎ入れることをいう。またフラワーアレンジメントに作用させるとは、例えば、フラワーアレンジメント用のバスケットまたは専用スポンジを入れた容器に本発明の切り花延命剤を注ぎ入れることをいう。本作用によって、切り花の水揚げを持続させ、切り花の日持ちを延長させることができる。 The cut flower life-prolonging agent of the present invention can act on cut flowers or flower arrangements. To act on cut flowers means, for example, pouring the cut flower life-prolonging agent of the present invention into a container for cut flowers. Further, acting on a flower arrangement means, for example, pouring the cut flower life-prolonging agent of the present invention into a basket for flower arrangement or a container containing a special sponge. By this action, the landing of cut flowers can be sustained and the shelf life of cut flowers can be extended.
フラワーアレンジメントとは、バスケットや専用スポンジに生花、茎、枝等を生けることをいう。フラワーアレンジメントの種類は、業務用においてはパーティやブライダルのブーケやアートとして、一般用においては観賞用や贈答用の商品として花屋で販売され活用されている。 Flower arrangement means to grow fresh flowers, stems, branches, etc. in a basket or a special sponge. The types of flower arrangements are sold and utilized at florists as party and bridal bouquets and art for business use, and as ornamental and gift items for general use.
