Description

식물 성장 촉진제Plant growth promoters

본 발명은 식물 성장 촉진제에 관한 것이다. 좀더 상세하게는 식물 재배에 관한 농업분야, 특히 식물의 성장을 촉진할 수 있는 2-메틸-4-디메틸아미노메틸-5-하이드록시벤즈이미다졸(2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazol)의 용도에 관한 것이다.The present invention relates to plant growth promoters. More specifically, the agricultural field of plant cultivation, in particular 2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazole which can promote plant growth It relates to the use of.

종래에 알려진 식물성장 조절제로 유용한 N-알킬-N-아실아민 유도체(N-아실알라닌 유도체)는 농작물의 보호를 위한 살균제로서 사용될 때 매우 우수한 효과를 나타내는 것으로 알려져 있으며, 대상 농작물로는 곡류, 쌀, 채소, 사탕무우, 대두, 땅콩, 과일나무, 호프, 오이류(오이, 호박, 참외), 가지과 식물(감자, 담배, 토마토), 바나나, 코코아 등에 사용할 때 우수한 효과를 나타낸다. N-알킬-N-아실아민 유도체는 그에 대해 각국에서 특허된 제법이 알려져 있으나 수율이 비교적 낮으며, 식물의 성장을 직접적으로 촉진한다기 보다는 탁월한 살균력으로 병균의 감염을 방지하여 식물을 잘 자라게 한다는 간접적 효과를 가지는 것에 불과하다. 또한 식물의 성장을 촉진하는 것으로서 인돌아세트산, 지베렐린, 벤질아미노푸린, 인돌부티린산 등을 둘 이상 혼합한 용액을 사용하여 왔으나 모두 수입품으로서 고가일 뿐만 아니라 용액 제조시 지베렐린이외에는 물에 잘 용해되지 않아 용해제로서 알콜을 사용해야함으로 알콜이 식물체 내로 침투하여 열을 발생시켜 식물을 시들게 하는 등 여러가지 문제점이 있었다.N-alkyl-N-acylamine derivatives (N-acylalanine derivatives) useful as conventional plant growth regulators are known to have a very good effect when used as fungicides for the protection of crops. It has excellent effects when used in vegetables, beets, soybeans, peanuts, fruit trees, hops, cucumbers (cucumbers, pumpkins, melons), eggplants (potatoes, tobacco, tomatoes), bananas, and cocoa. N-alkyl-N-acylamine derivatives are known in the world for their patented recipes, but their yields are relatively low, and they do not directly promote plant growth, but rather prevent infection of germs with excellent bactericidal powers to grow plants well. It only has an indirect effect. In addition, as a solution for promoting plant growth, a solution containing two or more of indole acetic acid, gibberellin, benzylaminopurine, and indolebutyric acid has been used. As alcohol has to be used, there have been various problems such as alcohol penetrating into the plant and generating heat to wither the plant.

본 발명은 종래에 사용되던 식물 성장 촉진제의 여러 문제점을 해결하고자 안출된 것으로, 아무런 부작용 없이 식물 성장을 촉진시켜 농산물 수확을 늘릴 수 있는 공지된 화합물의 새로운 용도로서의 사용을 개발하고자 하는 것이다.The present invention has been made to solve various problems of the conventional plant growth promoter, and is intended to develop a new use of the known compound which can increase the yield of agricultural products by promoting plant growth without any side effects.

식물자체의 성장 조절물질은 악조건 하에서도 꾸준히 자랄 수 있게 하는 일련의 과정을 거치게 한다. 이러한 성장 조절물질은 세포분열, 씨앗의 발아, 단백질과 RNA합성의 촉진, 엽록체의 광합성 작용을 활발하게 하고 꽃, 열매, 잎의 노화현상을 단백질과 핵에 관련된 효소의 억제작용을 통해 막아준다.Plant growth regulators undergo a series of processes that allow them to grow steadily under adverse conditions. These growth regulators promote cell division, seed germination, protein and RNA synthesis, chloroplast photosynthesis, and aging of flowers, fruits, and leaves through inhibition of enzymes related to proteins and nuclei.

따라서, 본 발명은 식물체내의 성장 조절물질과 유사한 작용을 하는 물질을 찾아내는데 그 목적이 있다.Therefore, an object of the present invention is to find a substance that acts similar to a growth regulator in a plant.

본 발명은 하기 화학식 1로 표시되는 2-메틸-4-디메틸아미노메틸-5-하이드록시벤즈이미다졸(2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazol)의 식물 성장 촉진제로서의 용도에 관한 것이다. 본 발명 화합물은 벤즈이미다졸 화합물의 유도체로서 구 소련과학원의 물리화학연구소 연구팀에 의해 1981년 2월에 최초로 연구 개발된 것이다.The present invention relates to the use of 2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazole (2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazol) represented by the following formula (1) as a plant growth promoter. The compound of the present invention was firstly developed and developed in February 1981 by a research team of the Institute of Physical Chemistry of the former Soviet Academy of Science as a derivative of the benzimidazole compound.

본 발명자는 벤즈이미다졸 유도체를 식물의 성장을 촉진시키기 위해 이용하고자 연구를 거듭한 결과 상기 2-메틸-4-디메틸아미노메틸-5-하이드록시벤즈이미다졸 및 그 염산염 2-메틸-4-디메틸아미노메틸-5-하이드록시벤즈이미다졸·2HCl이 식물의 성장점에서 세포분열을 촉진하여 뿌리의 성장을 촉진시키는 것을 발견하였다. 뿌리에서 신장과 분화의 경계가 되는 부분을 자세하게 관찰해 보면, 본 발명 5-하이드록시벤즈이미다졸 유도체는 신장을 유도하게 되는데, 특히 세포질의 성장을 47%이상 증가시키는 것을 확인할 수 있었다.The present inventors have conducted studies to use benzimidazole derivatives for promoting plant growth, and as a result, 2-methyl-4-dimethylaminomethyl-5-hydroxybenzimidazole and its hydrochloride 2-methyl-4-dimethyl It was found that aminomethyl-5-hydroxybenzimidazole.2HCl promoted cell division at the growth point of the plant to promote root growth. Observing in detail the portion of the root that is the boundary between kidney and differentiation, the 5-hydroxybenzimidazole derivatives of the present invention induced the kidney, in particular, it was confirmed that the increase in cytoplasmic growth of more than 47%.

이러한 5-하이드록시벤즈이미다졸 유도체의 식물성장촉진 기능은 식물의 자연적인 염색체의 변형을 1/2∼2/3로 감소시켜 유해한 돌연변이를 억제하는 능력과 동시에 살균작용을 함으로써 질병에 대항할 수 있는 특성에서 비롯되는 것이다.The plant growth promoting function of the 5-hydroxybenzimidazole derivatives can fight disease by reducing the natural chromosome deformation of the plant to 1/2 to 2/3 and inhibiting harmful mutations while simultaneously bactericidal. That comes from that characteristic.

본 발명 5-하이드록시벤즈이미다졸 유도체는 흰색 분말로 물에 잘 녹는 특성이 있어서, 주로 물에 용해시켜 용액상태로 이용하는 것이 바람직하다. 또한, 오래된 씨앗의 발아를 촉진하며, 종자에 처리하면 발아율이 증가할 뿐만 아니라 성장기에 질병에 강하고 수확량도 현저히 증가한다. 따라서, 본 발명에 따른 5-하이드록시벤즈이미다졸 유도체는 종자의 전처리 과정에서 이용될 수 있다.The 5-hydroxybenzimidazole derivative of the present invention is a white powder, which is well soluble in water, and is preferably dissolved in water and used in a solution state. In addition, it promotes germination of old seeds, and treatment with seeds not only increases the germination rate, but also is resistant to disease during the growing season and significantly increases the yield. Thus, the 5-hydroxybenzimidazole derivatives according to the invention can be used in the pretreatment of seeds.

5-하이드록시벤즈이미다졸 유도체의 최적 활성은 미량농도에서 발휘되므로 1ℓ의 물에 1mg의 농도가 적당하며, 주로 종자를 전처리하는 방법으로 이용되는 것이 바람직하다. 다음의 실시예로 본 발명이 보다 상세히 설명될 것이다.Since the optimum activity of the 5-hydroxybenzimidazole derivative is exerted at a trace concentration, a concentration of 1 mg in 1 L of water is suitable, and it is preferable to be mainly used as a method for pretreatment of seeds.
