激光作为育种手段已被应用了多年并且产生了许多良好的效果。但在这个领域中仍有许多具体问题有待于探索,如对某种作物或品种应用何种激光、什么剂量使其向人们预期的方向发展等等。我们以氦-氖激光为光源对蕃茄的两个品种的种子进行了不同功率密度、不同时间 Laser has been used as a breeding tool for many years and has produced many good results. However, there are still many specific problems to be explored in this field, such as what kind of laser is applied to a certain crop or variety, what dose should be made to be expected in the future, and so on. We use helium-neon laser light source of two varieties of tomato seeds of different power density, different time
