为了寻求新的诱变源和探索新的诱变处理方法,我们进行了远红外激光、~(60)Co-γ射线及其复合处理水稻干种子以提高诱变效果的研究。供试材料为“湘早籼1号”干种子,辐照源为~(60)Co-γ射线和远红外激光。处理方法按γ射线与激光单独处理、γ射线和激光复合处理及对照等不同的组合共10种。γ射线的处理剂量为3万伦琴。远红外激光波长为118.8μm。处理时间为30分钟和60分钟,激光工作状态的输出电压讯号分别为2-5V与6-9V,本文仅对其当代生物学效应进行阐述。
In order to find new mutagenic sources and to explore new mutagenesis methods, we conducted far-infrared laser, ~ (60) Co-γ-ray and its composite treatment of dry seeds of rice to improve the mutagenic effect. The test material was “Xiangzaoxian 1” dry seed, and the irradiation source was ~ (60) Co-γ ray and far-infrared laser. Treatment methods by γ-rays and laser alone, γ-ray and laser composite treatment and control of a total of 10 different combinations. γ-ray treatment dose of 3 million Roentgen. The far-infrared laser wavelength is 118.8 μm. The processing time is 30 minutes and 60 minutes. The output voltage signals of the laser working state are 2-5V and 6-9V respectively. This article only expounds the contemporary biological effects.
