激光是一种受激跃迁的辐射光,它与生物有机体相互作用,使染色体和遗传物质分子(DNA)结构发生改变,从而导致性状和特性的变异,这种变异通过遗传复制可以留给后代以形成新的良种.十几年来国内外关于激光在农作物上的应用有不少报导,美国、苏联、加拿大、澳大利亚和我国中山大学、四川大学、复旦大学、浙江农学院等单位,采用多种激光器对稻、麦、蚕豆、首蓿、南瓜、西红柿和甜菜进行了辐处,取得了促进生长,增加糖价、蛋白质和维生素等效果.澳大利亚阿德莱特大学曾用氦一氖激光连续几个晚上对甘蔗植株进行辐射,抑制了开花速度,从而延长了营养生长期,提高了产量.我院蔗麻研究所一九七六 Laser is a stimulated radiation that interacts with biological organisms to change the structure of chromosomes and genetic material (DNA), resulting in variations in traits and traits that can be passed on to offspring by genetic duplication A new breed has been formed.Recently, there are many domestic and foreign reports on the application of laser on crops. The United States, the Soviet Union, Canada, Australia and China’s Sun Yat-sen University, Sichuan University, Fudan University, Zhejiang Agricultural College and other units use a variety of lasers Irradiation of rice, wheat, broad beans, first crop, pumpkin, tomato and sugar beet has resulted in effects that promote growth, increase sugar, protein and vitamins etc. Australia’s Adelaide University used helium-neon laser for several nights in a row Irradiation of sugar cane plants, inhibition of the flowering rate, thereby extending the vegetative growth period and increase the yield of our Institute of sugarcane hemp one nine seven six
