Mutation breeding device capable of effectively improving chemical mutation efficiency

Abstract

The invention discloses a mutation breeding device capable of effectively improving chemical mutation efficiency. The mutation breeding device comprises a mutation breeding box and a conductivity monitor, a plurality of supporting legs are arranged on the bottom side wall of the mutation breeding box, a conductivity motor probe rod is arranged on the conductivity monitor, a mounting shell is fixedly connected to one outer side wall of the mutation breeding box, an empty groove is formed in the side wall, close to the mounting shell, of the mutation breeding box, and the mutation breeding box communicates with the mounting shell through the empty groove. According to the mutation breeding device capable of effectively improving the chemical mutation efficiency, through the design of the mounting shell, a strong electrolyte solution and a semipermeable membrane, the concentration change of the chemical mutagen solution in the mutation breeding box is indirectly monitored in real time byvirtue of the conductivity monitor, so that seeds can be quickly taken out after the total seed absorption amount reaches an expected suitable amount, therefore, the fatality rate in the mutagenesis process can be stably and effectively reduced, the number of mutants is increased, the mutagenesis probability is increased, and the purpose of improving the chemical mutagenesis efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of research and development of biological breeding, in particular to a mutation breeding device for effectively improving the efficiency of chemical mutagenesis. Background technique [0002] Biological breeding is the process of cultivating new biological varieties using methods and principles such as genetics, cell biology, and modern bioengineering technology. The breeding methods introduced in high school mainly include: hybrid breeding, mutation breeding, polyploid breeding, haploid breeding, cell engineering breeding (tissue culture breeding), genetic engineering breeding (transgenic breeding), etc. Among them, mutation breeding has gradually become the mainstream direction of cultivating new plant varieties in recent years by virtue of the advantages of being able to create new genes and obtain new traits. [0003] Mutation breeding methods can be divided into physical methods and chemical methods. A...

Problems solved by technology

For the chemical mutagenesis of plant seeds, it is generally soaked in a chemical mutagen solution for a long time, so that the chemical mutagen fully penetrates into the seeds. After the seeds absorb the chemical mutagen, mutations occur probabilistically. The amount of chemical mutagen absorbed by the seeds is related to the dose. If the absorbed dose is too high, the seeds are prone to severe physiological damage, and then they cannot survive and grow normally. If the absorbed dose is too small, the probability of mutation will be low, and the number of mutants will be too small. However, in the existing chemical mutation breeding process, it is difficult to control the absorbed dose of the seeds due to the extremely low concentration of the chemical mutagen solution used. , resulting in low mutagenesis efficiency
