Description
Technical Field
The utility model relates to the field of tissue culture, in particular to the field of plant tissue culture vessels, and specifically relates to an explant disinfection device in a plant tissue culture process.
Background
A beaker is selected as a disinfection container in the plant culture process, and when explants (such as rice ears, wheat ears and the like) are disinfected, the explants need to be continuously pressed by tweezers, so that the explants are fully contacted with a disinfectant, otherwise, the explants cannot be thoroughly disinfected. The explant is easy to drop when pouring the liquid in the beaker, or the liquid is difficult to pour out cleanly, and disinfectant residue is easy to cause.
The pollution rate reduction in the plant tissue culture process is the most key factor for improving the tissue culture efficiency, and the explant disinfection is the most important step for reducing the pollution rate. At present, a beaker is used as a container for sterilizing explants in the tissue culture process, long explants (such as rice ears) are vertically placed in the beaker, and short or blocky explants are directly placed in the beaker. After the disinfectant is added, the explants float up, influenced by the disinfectant and the specific gravity of the explants. Due to the fact that the number of disinfectants required to be poured into the explants such as rice ears is large, the ears can fall out of the beaker along with the increase of the volume of the disinfectants, the fallen explants cannot be used, and otherwise, subsequent experiment pollution is easily caused. In order to ensure that the explant is fully contacted with the disinfectant, the explant needs to be continuously pressed by using tweezers, otherwise incomplete disinfection of the explant is easily caused, and subsequent experiments are influenced. After the disinfectant treatment is finished, the disinfectant needs to be poured out, and then the explants are rinsed for multiple times by using sterile water, so that the explants are prevented from being poisoned by residual disinfectant. In actual operation, when the disinfection solution and the sterile water for rinsing are poured, due to the worry that the explants fall, a part of liquid is usually left at the bottom of the beaker, and the washing is not thorough, so that the disinfection solution remains in the explants, and toxic action is generated on the explants.
