Problems solved by technology

[0004] Still another object of the present invention is to provide a method for eliminating bacterial contamination of tissue culture seedlings. In this method, Chinese herbal medicines such as Houttuynia cordata, aloe vera, goose herb, Artemisia argyi, Huoxiang and garlic are added to the plant after reasonable compatibility and treatment. In the conventional culture medium, it is prepared as a decontamination medium, which is used to transfer contaminated tissue culture seedlings. This method has a good bactericidal effect and is easy to operate, and can solve the problems of unsatisfactory sterilizing effect, complicated operation, and easy secondary contamination in the prior art. Sub-pollution and problems with no promotional value

Abstract

The invention discloses a method for eliminating bacterial pollution of tissue culture seedlings. The method comprises the following steps: step A, weighing the following raw materials in parts by weight: herba houttuyniae, aloes, small centipeda herb, folium artemisiae argyi, herba pogostemonis and garlic; mixing the raw materials and then pulping or mixing the raw materials, adding water for immersing for a period of time and pulping to obtain Chinese herbal medicine pulp; step B, adding the Chinese herbal medicine pulp into a certain amount of conventional culture medium in parts by weight; uniformly mixing and then carrying out high-pressure sterilization to obtain a pollution removing culture medium; step C, transferring polluted tissue culture seedlings into the pollution removing culture medium and culturing for 7 to 10 days; step D, repeating the step A to the step C until pollution of the polluted tissue culture seedlings is eliminated, so as to obtain pollution-removed culture medium seedlings; step E, transferring the pollution-removed culture medium seedlings into the conventional culture medium and continually culturing. The method disclosed by the invention has the advantages of good sterilization effect, small damages to the culture medium seedlings, low cost, and simplicity and convenience for operation, and is suitable for industrial popularization and the like.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture. More specifically, the present invention relates to a method for eliminating bacterial contamination of tissue culture seedlings. Background technique [0002] In the process of plant tissue culture, pollution is one of the three major problems in the current tissue culture process. Due to various reasons, bacterial contamination of tissue culture seedlings occurs, and the contaminated tissue culture seedlings are generally discarded and used in production. Contaminating bacteria grow rapidly during the process and are easy to spread. If not handled properly, it will cause a devastating blow, increase production costs, and often cause irreparable losses to the preservation of plant resources. At present, in tissue culture, antibiotics are mostly used for sterilizing treatment, but so far no antibiotics have been found to be effective against various bacteria, and the effect is not i...
