摘要
本文讨论了在玉米抽穗和杨花期大田里进行的人工诱发闪电试验中测定的闪电击地点附近电磁场的变化以及收获时发现的闪电击地点及闪电主分流电流通路附近的大田玉米单株双穗率和雄花结穗率比对照地段高出4倍和2.8倍的现象。这种现象类似于其它物理因素诱发变异的结果。如果今后能得到重复,所得变异株能够遗传,那将可以作为自然界物种演变的一种佐证,使人工诱发闪电实验成为生物基因诱变的大田实验场所。
In this paper, the artificially triggered lightning in the maize field during the earing and flowering stages was discussed. The change of the electromagnetic field near the stroke points was measured. It was found that the rates of two earing and the earing of male flower of the maize near the stroke points and the thoroughfare of igniting wire of artificially triggered lightning in the crop field are much greater. They are 4 times and 2.8 times higher than in common one respectively. The phenomenon is the same as that of mutation induced by physical factors. If it can repeat and the mutation can inherit, it must be one of the evidence of the evolution of life in nature.
