从六十年代始,人们便开始了在农业上应用激光的研究。据报道:美国、加拿大用激光对蚕豆、萝卜和南瓜种子处理后生长明显加快;苏联用He-Ne激光处理蕃茄和黄瓜种子,能提高其发芽率和促进发育。我国激光技术发展也很快,曾有人用各种激光对一些粮食、蔬菜等作物的种子进行了处理,均能不同程度促使种子提前发芽、成熟,达到增产的目的。这些实验为激光在农业上的应用开辟了广阔前景。而激光用于海藻育种方面的实验,很少有报道。我们于1978年开始用海带雌配子体作材料进行激光生物学效应的探索实验。拟为海藻 Since the 1960s, people began to apply laser research in agriculture. It has been reported that the growth of Vicia faba, radish and pumpkin seeds in the United States and Canada was significantly accelerated by lasers. In the Soviet Union, tomato and cucumber seeds were treated with He-Ne laser to increase their germination rate and promote development. The development of laser technology in China is also very fast. Some people used various kinds of lasers to treat the seeds of some crops such as grain, vegetables and so on, all of which can promote the seeds to germinate and mature ahead of schedule and achieve the purpose of increasing production. These experiments opened up broad prospects for the application of lasers in agriculture. The laser for seaweed breeding experiments, rarely reported. We began in 1978 with the kelp gametophyte material for laser biological effects of exploration experiments. Proposed as seaweed
