Application of Gamma and Beta Rays in Agricultural Seed Improvement Technology

abstract

With the advancement of technology, the application of nuclear technology in the field of agriculture is becoming increasingly widespread, especially in seed improvement, which has shown great potential. Gamma (γ) rays and beta (β) rays, as important components of nuclear technology, are widely used in agricultural seed mutagenesis breeding and sterilization treatment due to their unique physical properties. This article aims to explore the application principles, methods, effects, and future development directions of gamma and beta rays in agricultural seed improvement technology.



introduction

Agriculture is the foundation of the national economy, and as the starting point of agricultural production, the quality of seeds directly affects the yield and quality of crops. Although traditional seed improvement methods such as hybrid breeding have achieved certain results, they have problems such as long time consumption, high cost, and unstable genetic variation. In recent years, with the development of nuclear technology, gamma and beta rays have shown unique advantages in agricultural seed improvement due to their unique physical effects.

Application of Gamma Ray in Agricultural Seed Improvement

Radiation induced breeding

Gamma rays have become an important tool for radiation induced breeding due to their high energy and strong penetration. When seeds are exposed to a certain dose of gamma rays, their DNA strands are damaged and may undergo incorrect repairs during the repair process, leading to changes in DNA structure and causing variations in cellular expression traits. This variation includes increased yield, improved quality, and enhanced stress resistance. Researchers can cultivate new varieties with excellent traits by screening these mutated seeds.

Sterilization treatment

Gamma rays also have strong bactericidal ability, which can effectively inhibit the growth of bacteria, fungi and other microorganisms on the surface of seeds, thereby reducing the incidence of seed diseases during storage and planting. Compared with traditional chemical sterilization methods, gamma ray sterilization has no residue and no pollution, which is more in line with the requirements of modern agricultural green development.



Potential application of beta rays in agricultural seed improvement

Although the direct application of beta rays in agricultural seed improvement is relatively limited, their unique physical properties make them potentially valuable in specific fields. For example, beta rays can be used for local treatment of seeds, achieving targeted improvement of specific traits by precisely controlling the irradiation area and dose. In addition, beta rays can also be used for biological labeling and tracking of seeds, providing technical support for quality monitoring and anti-counterfeiting of seeds.
