ESR条件下的微波辐射对小麦种子萌发过程的影响

本文把2个小麦品种(法国和中国春小麦)经浸泡17h已开始萌动的种子暴露于具有特定共振条件的电子自旋共振(ESR)场72h,实验选用的高频电磁场频率分别为v_1=147.9MHz,v_2=53.6MHz,v_3=84.4MHz。实验结果显示,频率为147.9MHz和84.4MHz的ESR高频场对萌发种子胚芽的生长有抑制效应,其抑制峰分别在H_0=2.15A,2.25A处和H_1=3.5V处;而频率为53.6MHz的ESR场对种子胚芽生长则有促进作用,其促进峰在H_1=4.0V。这种依共振条件为转移的ESR生物学效应是一种非热致效应。本工作证实了ESR场对萌发胚芽生长有调控作用。这就从实验方面支持和丰富了Frohlich提出的关于非热致生物学效应机制的理论。

The Effects of Microwave Radiation under ESR Conditions on Germination Process of Seeds of Spring Wheat

The Present relates the experiment that the seeds of two strains of French and Chinese spring wheat, on the verge of germination after being soaked for 17 hours, were exposed in the ESR field under specific conditions of resonance for 72 hours, with frequencies of the high-frequency electromagnetic field respec-tively of v_1=147. 9MHz, v_2=53. 6MHz, and v_3=84. 4MHz. The result of the experi-ment, indicates that ESR fields of 147. 9MHz and 84. 4MHz have an inhibition effect on the growth of the plumule of the wheat seeds, with its inhibition peak being at H_0=2. 15A, 2. 25A and H_1=3. 5V, while the ESR field of 53. 6MHz has an acceleration effect on the plumule, with its acceleration peak being at H_1=4. 0V.This biological effect which varies depending on resonance conditions is a nonther-mal effect. The experiment has proved that ESR field has an effect of ajustment and control an the growth of the plumule of the seed, which supports and enrich-es experimentally the theory produced by Frohlich on the machenism of the non-thermal biological effect.
