摘　　要：用激光加电场进行育种研究 ,发现静电场和激光的作用效果是不相同的。这反映了它们与生物组织的相互作用机制的差异。本文用量子力学对此差异进行了解析分析 ,并与育种试验结果进行印证。得出电场辐照种子 ,可降低蛋白质分子的能级 ,增加种子的生物活性 ;激光辐照种子 ,有可能使DNA的构象发生变化 。With laser and electric field irradiated to seed cultivation, it is discovered that the effect of electric field and laser is difference. This paper studied the difference effect by quantum mechanics method, and the result has compared with experiment data of seed cultivation. The electric field irradiated on the seed, can reduce the energy gap of protein molecular, and can increase seed activity. The laser irradiated on the seed, may change structure of DNA, so make the mutation is achieved partly.
