It was shown that the rate of gravitropic response in apical segments excised from the 4-day-old seedlings of flax (Linum bienne) may be substantially influenced by combined magnetic fields (CMF) of two different types: 1) CMF tuned to the parametric resonance for Ca2+; 2) CMF containing extremely weak alternating component with the values of magnetic density ranging from 10(-6) to 10(-10) T. Our experimental data indicate that CMF affect the gravitropic response via at least two different mechanisms. The first one corresponds to the ion parametric resonance well established earlier in studies with test-systems prepared from animals. The origin of the bioeffects induced by CMF containing extremely weak alternating component remains to be established.
结果表明，从4日龄亚麻（亚麻属二年生植物）幼苗切下的顶端切段的向重力性反应速率，可能受到两种不同类型的复合磁场（CMF）的显著影响：1）调谐到Ca2+参数共振的CMF；2）包含极其微弱交变分量且磁密度值范围为10（-6）至10（-10）T的CMF。我们的实验数据表明，CMF至少通过两种不同机制影响向重力性反应。第一种机制对应于早期在由动物制备的测试系统研究中已充分确立的离子参数共振。含有极其微弱交变分量的CMF所诱导的生物效应的起源仍有待确定。
