Abstract

Magnetic field oscillations resulting from atmospheric events could have an effect on growth and development of plants and on the responsive reactions of plants to other environmental factors. In the current work, extremely low-frequency magnetic field (14.3 Hz) was shown to modulate light-induced electric reactions of wheat (Triticum aestivum L.). Blue light-induced electric reaction in wheat leaf comprises depolarization and two waves of hyperpolarization resulting in an increase of the potential to a higher level compared to the dark one. Fluorescent and inhibitory analysis demonstrate a key role of calcium ions and calcium-dependent H⁺-ATPase of the plasma membrane in the development of the reaction. Activation of H⁺-ATPase by the increased calcium influx is suggested as a mechanism of the influence of magnetic field on light-induced electric reaction.

极低频磁场对小麦光致电反应的影响。

大气事件引起的磁场振荡可以影响植物的生长发育以及植物对其他环境因子的响应。本研究表明，极低频磁场(14.3 Hz)可调节小麦(Triticum aestivum L.)光致电反应。蓝光诱导的小麦叶片电反应包括去极化和两波超极化，导致电势比暗电势增加到更高的水平。荧光和抑制分析表明，钙离子和钙依赖的质膜H+- atp酶在反应的发展中起关键作用。钙内流增加激活H+- atp酶被认为是磁场影响光致电反应的机制之一。
