What are the economic benefits of micropropagation, and what is the difference between micropropagat

Micro-propagation is highly economical.

There are short branch cuttings, bud proliferation, protocorm, organ differentiation and embryogenesis. There are many varieties of suitable species, according to the literature, there are more than 1,500 plant species that have been successfully cultivated in tissue culture, and there are hundreds of species that can be industrially produced. It is especially suitable for the rapid propagation of plants that cannot be propagated by cuttings, such as orchids, lilies, gerberas, etc.

Although tissue culture of woody plants is more difficult than herbaceous, through the efforts of scientific researchers, it has been successful in many plants such as poplars and eucalyptus.

1. Propagation with test-tube fast propagation technology can save propagation materials, and only a small piece of tissue or organ on the raw material can produce a large number of high-quality seedlings required by the market in a short period of time, and tens of thousands or even millions of small plants can be propagated every year, which can not damage the raw materials and obtain higher economic benefits. In vitro propagation is a kind of miniature asexual reproduction, which is derived from somatic cells of the same individual rather than sex cells, so the heritability of its offspring is very consistent, and it can maintain the excellent traits of the original variety. It has a special effect on quality and purity.

A large number of seedlings of uniform specifications and high quality can be obtained, and the seedlings have good commerciality. In vitro fast multiplication is an intensive production carried out under artificially controlled conditions, which is not affected by the seasons and bad weather in the natural environment. Therefore, it is not limited by the season, and continuous production can be carried out throughout the year, and the production efficiency is high.

From the extraction, inoculation, cultivation, rooting, transplanting, can be produced like a factory, so the application of this technology in agriculture is called a "revolution" in agriculture. It has a special role in off-season production, such as flowers such as upside-down Admiralty and Begonia that are not resistant to high temperature in summer, and can be produced in tissue culture seedlings in the culture room in summer and flower production in autumn.

2. The method of shoot tip culture or combined with heat treatment is used to remove the viruses, fungi and bacteria of most plants, so that the plant growth is strong, the flowers are enlarged, the color is bright, the stress resistance is improved, and the number of flowers is increasedRapid propagation of flower tissue culture Because the seedlings grow in culture flasks and are placed in three dimensions, the space required is small and the land is saved. The production can be strictly implemented according to certain procedures, and the production process can be miniaturized and precise, which can maximize the human, material and financial resources and achieve high production efficiency, such as producing millions of test-tube seedlings in a 200-square-meter culture room a year.

If calculated at 1 yuan per plant, the annual output value is millions of yuan.

Plant tissue culture technology (micro-propagation) can not only maintain the genetic characteristics of excellent varieties, but also efficiently and quickly achieve the mass propagation of seedlings.

Micropropagation is actually tissue culture, but it is a factory application of tissue culture, pursuing yield and speed. benefits, etc.

Plant tissue culture technology can not only maintain the genetic characteristics of excellent varieties, but also efficiently realize the mass propagation of seedlings, so people vividly use the plant tissue culture technology for rapid propagation of excellent varieties, called plant micro propagation technology, also called rapid propagation technology. At present, some excellent ornamental plants, economic forest trees, and vegetatively propagated crops have realized the use of rapid propagation technology to provide seedlings. Test-tube seedlings of orchids, lettuce, poplars and seedless watermelons have all been industrialized.

As early as the turn of the century, scientists in the Netherlands successfully implemented the use of tissue culture technology to cultivate orchids. At present, the orchid production in the Netherlands has developed into a world-famous orchid industry, which generates huge foreign exchange earnings for the Netherlands every year.

Summary. Concept: It is a plant tissue culture technology that quickly and efficiently realizes seedling multiplication and cultivation of excellent plant varieties (1) Micro propagation technology: also known as rapid propagation technology Plant tissue culture technology that rapidly propagates excellent varieties.

2) Characteristics: a. Maintain the genetic characteristics of excellent varieties;

b. Efficiently and quickly realize the mass propagation of seedlings.

3) Advantages: Less material from the plant body, short cultivation cycle, high reproduction rate, easy to automate management.

For example, one orchid shoot tip can produce 4 million orchid seedlings in a year.

Answer: People call the plant tissue culture technology used for the rapid propagation of excellent varieties as the micro-propagation technology of plants, also known as the rapid propagation technology.

Micropropagation, which is what we call plant tissue culture; haplotype sport; utilization of mutants; crop detoxification; Factory production of cell products.

The use of plant micro-propagation technology to propagate plants is to use its advantages (characteristics): one is efficient and fast reproduction, and the other is to maintain the genetic characteristics of excellent varieties. That is, high efficiency and maintaining the excellent genetic characteristics of the seedlings.

Plant "micro" propagation technology has the advantage of high efficiency and the ability to maintain the excellent genetic characteristics of seedlings. Factory seedling production takes advantage of these two advantages of this technology.

The use of plant micropropagation technology to propagate plants is to take advantage of their characteristics: first, efficient and rapid reproduction, and second, to maintain the genetic characteristics of excellent varieties. That is, high efficiency and maintaining the excellent genetic characteristics of the seedlings.

The reproduction speed is fast, the reproduction coefficient is large, the reproduction methods are many, the excellent traits of the original variety can be maintained, the detoxified seedlings can be obtained, the annual factory production can be carried out, and the economic benefits are high.
