Advantages and disadvantages of tissue culture seedling production

advantage

1.Asexual reproduction is possible. For some plants that are difficult to reproduce asexually in production, or plants that cannot be reproduced asexually, a large number of vegetative seedlings can be obtained in a short period of time under the special conditions of tissue culture. Tissue culture mainly uses the principle of asexual reproduction, takes the tissue or cells of the plant, and then conducts large-scale culture. Therefore, it has a very significant advantage in that the reproduction speed is fast, and it is mainly suitable for large-scale cultivation of the next generation of plants.

2.Tissue culture can maintain the excellent characteristics of the parent. That is to say, the female parent that can produce red flowers, the new plant cultured from its tissue will also produce red flowers, and the possibility of mutation is very small.

3.Tissue culture can manually control the culture conditions, and will not be limited by the uncontrollable factors of weather and season. Therefore, it also has the advantage of high production efficiency, which can effectively reduce the expenditure of human and financial resources.

4.can maintain the inherent characters and characteristics of the original varieties.

5.Save breeding material. Collecting a small number of vegetative organs can produce a large number of flower seedlings.

6.Breeding fast. A small piece of tissue taken from a healthy mother plant and cultured in vitro under suitable conditions can produce thousands of seedlings within a year.

7.Avoid getting viruses. At present, many plants are seriously infected with viruses, which affects the ornamental and export of plants. It can be detoxified by tissue culture, making it a non-toxic seedling.

shortcoming

1.Compared with traditional cuttings and grafting, tissue culture requires stricter conditions and certain requirements for equipment. It is necessary to ensure a sterile environment during cultivation, which requires a certain amount of investment.

2. Tissue culture must first prepare a suitable medium, but it is difficult to find a suitable medium for a variety of plants, which requires gradual experimental screening and a certain period. This also brings some difficulties to the popularization of tissue culture.

3. The biggest difficulty of tissue culture is to reduce the contamination rate of tissue culture seedlings and improve the survival rate of tissue culture seedling transplantation. Although tissue culture can cultivate many seedlings, the ability of seedlings to adapt to the environment is poor, and the overall technical and practical requirements are limited general application of tissue culture.
