激光育种是辐射诱变育种的一个新方法。近年来,利用氮激光照射作物种子、花粉、胚芽或微生物等,效果较好,为培育新品种提供了有利条件。但是,因为氮激光器输出的是极窄脉宽的不可见光脉冲,具有极高的谐波成分和极小的占空因素,若用目前实验室常用的“光-热”、“光-电”和“光-压”等方法 Laser breeding is a new method of radiation mutation breeding. In recent years, the use of nitrogen laser irradiation of crop seeds, pollen, germ or microorganisms, the better, for the cultivation of new varieties provide favorable conditions. However, because the output of the nitrogen laser is a very narrow pulse width of the invisible light pulse, with a very high harmonic content and a very small duty factor, with the current laboratory commonly used “light - heat”, “light - electricity” And “light - pressure” and other methods
