Description
技术领域 technical field
本发明涉及一种组织培养的植物再生技术领域，具体涉及一种新型的植物组织培养瓶。 The invention relates to the technical field of tissue culture plant regeneration, in particular to a novel plant tissue culture bottle.
背景技术 Background technique
1902年德国植物学家哈伯兰特提出“植物细胞全能性”理论，1958年美国植物学家斯蒂瓦特等人用胡萝卜韧皮部的细胞进行培养，获得了能够开花结果的完整植株，证实了“细胞全能性”这一预言，从而造就了一项新技术——植物组织培养技术，广义上又叫“立体培养”。植物组织培养技术不仅是无性繁殖和种苗快速繁殖的重要手段，也是细胞杂交、基因改良等技术体系的重要组成部分。通过建立一个适宜的快速组织培养体系，不仅解决了其野生资源日渐枯竭的现实问题，也能为细胞杂交、转基因等生物技术遗传改良打下坚实基础。以兰科植物为例，正如Arditti和Emes在《MicropropagationofOrchids》一书中所说的那样，“复印机和兰科组培技术的同时问世，使得世界从此不再一成不变”。 In 1902, German botanist Haberlandt proposed the theory of "plant cell totipotency". In 1958, American botanist Stewart and others used carrot phloem cells to cultivate and obtained a complete plant capable of flowering and fruiting, confirming the "totipotency of plant cells". The prediction of "cell totipotency" has created a new technology - plant tissue culture technology, which is also called "three-dimensional culture" in a broad sense. Plant tissue culture technology is not only an important means for asexual reproduction and rapid seedling propagation, but also an important part of technical systems such as cell hybridization and genetic improvement. By establishing a suitable rapid tissue culture system, it not only solves the practical problem of the depletion of its wild resources, but also lays a solid foundation for the genetic improvement of biotechnology such as cell hybridization and transgenic. Take orchids as an example, as Arditti and Emes said in the book "Micropropagation of Orchids", "The simultaneous advent of copiers and orchid tissue culture technology has made the world no longer the same."
植物受自身生物学特性、生态环境等因素的限制，野生资源已日渐枯竭，尤其是药用植物资源，自然条件下发芽率极低，生育周期相对较长，在一定程度上增加了生产成本而降低了经济效益。如何在较短时间内获得大量种苗，缩短培养周期，降低成本，成为生产过程中急需解决的问题。因此，通过组织培养技术，提高种子发芽率，人工快速繁殖种苗是保护植物资源和解决产业化对种苗需求的有效途径。 Plants are limited by their own biological characteristics, ecological environment and other factors, and wild resources have been depleted day by day, especially medicinal plant resources. Under natural conditions, the germination rate is extremely low and the growth cycle is relatively long, which increases production costs to a certain extent. Reduced economic benefits. How to obtain a large number of seedlings in a short period of time, shorten the cultivation period, and reduce costs have become urgent problems in the production process. Therefore, it is an effective way to protect plant resources and meet the needs of industrialization for seedlings by improving the germination rate of seeds through tissue culture technology and artificial rapid propagation of seedlings.
植物组织培养瓶为组织培养营造了一个无菌的环境，当前使用的组织瓶主要由瓶身、瓶盖或瓶塞组成，一方面，瓶身为一体成型，当加入培养基后培养基与瓶口距离较远，不利于操作，尤其是根系发达的植物；瓶内外空气流通差，当内外温差大时就造成瓶壁积水或水雾，不利于实验拍照记录，甚至增加污染率，另一方面，细小的瓶口在组培苗经炼苗移栽取苗时易损伤植物的根、茎、叶，进而影响植株的存活率。 Plant tissue culture bottles create a sterile environment for tissue culture. Currently used tissue bottles are mainly composed of bottle body, bottle cap or bottle stopper. On the one hand, the bottle body is integrally formed. The mouth is far away, which is not conducive to operation, especially for plants with well-developed root systems; the air circulation inside and outside the bottle is poor, and when the temperature difference between inside and outside is large, it will cause water or mist on the wall of the bottle, which is not conducive to taking photos and recording experiments, and even increases the pollution rate. On the one hand, the small bottle mouth is easy to damage the roots, stems and leaves of the plants when the tissue culture seedlings are transplanted and taken out, which in turn affects the survival rate of the plants.
发明内容 Contents of the invention
本发明意在提供一种新型的培养瓶，以解决一体成型的瓶身带来操作不变、实验记录不清晰以及移栽时容易损伤植物的缺陷。 The present invention intends to provide a new type of culture bottle to solve the defects of unchanging operation, unclear experimental records and easy damage to plants during transplanting due to the integrally formed bottle body.
本方案中的一种新型的植物组织培养瓶，包括相互套接可拆卸的瓶罩和瓶缸，所述瓶罩包括圆柱形瓶身以及与瓶身一体成型的弧顶，所述弧顶的中部设有进气管，瓶身上且与弧顶的结合处的下部设有出气管；瓶缸的高度为瓶身高度的1/3~1/2，所述瓶身与瓶缸相对密封，所述瓶缸底部连接有瓶托。 A new type of plant tissue culture bottle in this solution includes a bottle cover and a bottle cylinder which are mutually socketed and detachable. The bottle cover includes a cylindrical bottle body and an arc top integrally formed with the bottle body. There is an air inlet pipe in the middle, and an air outlet pipe on the lower part of the bottle body and at the junction with the arc top; the height of the bottle cylinder is 1/3~1/2 of the height of the bottle body, and the bottle body and the bottle cylinder are relatively sealed, so The bottom of the bottle jar is connected with a bottle holder.
本发明的工作原理及有益效果:本发明通过对兰科植物石斛、白及的组织培养总结，设计了一种组合分体闭合式培养瓶，瓶罩密封可拆卸连接在瓶缸上方，将瓶罩与瓶缸形成分体结构，瓶缸的大小即为管径大小，宽大的管径尤其适用于根系发达的植物，需要操作、实验记录拍照以及炼苗移栽时，将瓶罩与瓶缸分离即可。具有便于直视下操作、不宜损伤植物的根、茎、叶的优点，当瓶身与瓶缸套接闭合时，瓶罩与瓶缸形成植物生长相对的密封空间，瓶罩上的进气管和出气管通过与外界空气流通，能有效地解决培养瓶内外温差造成的瓶壁积水或水雾；同时通过瓶壁上的进气管向瓶内通入气体增加植物光合作用，有效解决当前植物组培瓶的缺陷，为植物组织培养提供器具保障，且具有非常广阔的市场前景。 Working principle of the present invention and beneficial effect: the present invention has designed a kind of combination split closed type culture bottle by summarizing the tissue culture of Orchidaceae dendrobium, white and, the bottle cover seal is detachably connected on the top of the bottle vat, the bottle The cover and the vat form a split structure.

It has the advantages of being easy to operate under direct vision and not harmful to the roots, stems and leaves of plants. When the bottle body and the bottle cylinder are sleeved and closed, the bottle cover and the bottle cylinder form a sealed space where the plants grow opposite. The air intake pipe on the bottle cover and the The outlet pipe communicates with the outside air, which can effectively solve the water accumulation or water mist on the bottle wall caused by the temperature difference between the inside and outside of the culture bottle; at the same time, the gas is introduced into the bottle through the air inlet pipe on the bottle wall to increase the photosynthesis of plants, effectively solving the problem of current plant composition.
