The Schumann Resonances (ScR) are Extremely Low Frequency (ELF) electromagnetic resonances in the Earth-ionosphere cavity excited by global lightning discharges. ScR are the part of electromagnetic field (EMF) of Earth. The influence of ScR on biological systems is still insufficiently understood. The purpose of the study is to characterize the possible role of the plant cell redox metabolism regulating system in the Schumann Resonances EMF perception. Activity of catalase and superoxide dismutase, their isoenzyme structure, content of malondialdehyde, composition of polar lipids in leaf extracts of wheat and pea plants treated with short-time (30 min) and long-time (18 days) ELF EMF with a frequency of 7.8 Hz, 14.3 Hz, 20.8 Hz have been investigated. Short-time exposure ELF EMF caused more pronounced bio effects than long-time exposure. Wheat catalase turned out to be the most sensitive parameter to magnetic fields. It is assumed that the change in the activity of wheat catalase after a short-term ELF EMF may be associated with the ability of this enzyme to perceive the action of a weak EMF through calcium calmodulin and/or cryptochromic signaling systems.
舒曼共振（ScR）是全球闪电放电激发的地球 - 电离层腔中的极低频（ELF）电磁共振。ScR是地球电磁场（EMF）的一部分。人们对ScR对生物系统的影响仍了解不足。本研究的目的是表征植物细胞氧化还原代谢调节系统在舒曼共振电磁场感知中的可能作用。研究了用频率为7.8Hz、14.3Hz、20.8Hz的极低频电磁场进行短期（30分钟）和长期（18天）处理的小麦和豌豆植物叶片提取物中过氧化氢酶和超氧化物歧化酶的活性、它们的同工酶结构、丙二醛含量、极性脂质组成。短期暴露于极低频电磁场比长期暴露引起更明显的生物效应。结果表明，小麦过氧化氢酶是对磁场最敏感的参数。据推测，短期极低频电磁场作用后小麦过氧化氢酶活性的变化可能与其通过钙调蛋白和/或隐花色素信号系统感知弱电磁场作用的能力有关。
