Abstract

Magnetic field (MF) effects have been reported in plants' growth, seed germination, gene expression, and water consumption. Accordingly, magnetic treatments have been proposed as a sustainable alternative to improve yields. Nevertheless, a comprehensive quantitative assessment is needed to understand whether their effects are general, species-specific, or dependent on the experimental setting. We conducted a multilevel meta-analysis of 45 articles that studied 29 different plant species. A positive and neutral effect of a nonuniform MF was found on fresh weight and germination rate, respectively. A significant association was found between a uniform MF and germination. These results suggest that MFs improve plant growth. However, the effects are highly dependent on the experimental setting. This opens exciting questions about the biophysical mechanisms underlying the perception and transduction of this environmental cue and about the possible translation to agricultural practices. © 2023 Bioelectromagnetics Society.

均匀和非均匀磁场对植物生长的影响:一种荟萃分析方法

磁场对植物生长、种子萌发、基因表达和水分消耗的影响已被报道。因此，磁处理被认为是一种可持续的提高产量的替代方法。然而，需要进行全面的定量评估，以了解它们的影响是普遍的，是物种特异性的，还是取决于实验环境。我们对45篇研究29种不同植物物种的文章进行了多层次的荟萃分析。不均匀MF对鲜重和发芽率的影响分别为正效应和中性效应。在均匀的MF和萌发之间发现了显著的关联。这些结果表明，MFs促进了植物的生长。然而，效果高度依赖于实验环境。这开启了关于这种环境线索感知和转导的生物物理机制以及可能转化为农业实践的令人兴奋的问题。©2023生物电磁学学会。

期刊介绍： Bioelectromagnetics is published by Wiley-Liss, Inc., for the Bioelectromagnetics Society and is the official journal of the Bioelectromagnetics Society and the European Bioelectromagnetics Association. It is a peer-reviewed, internationally circulated scientific journal that specializes in reporting original data on biological effects and applications of electromagnetic fields that range in frequency from zero hertz (static fields) to the terahertz undulations and visible light. Both experimental and clinical data are of interest to the journal''s readers as are theoretical papers or reviews that offer novel insights into or criticism of contemporary concepts and theories of field-body interactions. The Bioelectromagnetics Society, which sponsors the journal, also welcomes experimental or clinical papers on the domains of sonic and ultrasonic radiation.
