Increasing demand for food and concerns over the environmental impact of agriculture has prompted the search for alternatives to many conventional farming practices. Reports on exposing seeds and plants at various developmental stages to static magnetic field (SMF) and non-ionizing electromagnetic fields (EMF) as a form of priming indicate some positive effects on seed germinability, growth rate, resistance to stress conditions, and improved yield. However, there exist some inconsistent reported treatment protocols and contradictory study outcomes that make it difficult to draw objective conclusions on the potential use of SMF and EMF as sustainable alternatives to improving crop growth and yield. It is equally essential to understand any adverse effects of exposing plants to SMF and EMF considering the abundance of their sources in the environment. In order to provide a more coherent overview of how plants respond to exposure to SMF and EMF not only in their observed effects of agronomic importance but also in the mechanisms of action of SMF and EMF in plant cells, we prepare a systematic map.
Literature will be identified by searching six bibliographic databases and three web-based search engines using terms obtained from the population, exposure, and outcome parameters of the research question. Primary research published in peer-reviewed journals and grey literature will be the source for the evidence map. Studies eligible for inclusion may involve: food crops and related research model plants exposed to SMF or non-ionizing EMF; treatment at all plant developmental stages excluding post-harvest improvement of food crops; and the presence of control groups. Eligible literature will be screened at the title, abstract, and full text levels. The validity of studies will not be critically appraised for the evidence map. A process of double extraction and coding of relevant information from eligible literature will be conducted. Within the evidence map, relevant data will be presented in the forms of text, graphs, tables, and figures. This will illustrate research trends, bring clarity to the evidence base concerning clusters of sufficient findings and areas of significant gaps, and inform stakeholders in decisions concerning research planning and policy formulation.
对粮食需求的不断增加以及对农业环境影响的担忧，促使人们寻找许多传统耕作方式的替代方法。有关将处于不同发育阶段的种子和植物暴露于静磁场（SMF）和非电离电磁场（EMF）作为一种引发形式的报告表明，这对种子发芽能力、生长速率、抗逆性以及产量提高有一些积极影响。然而，存在一些不一致的报道处理方案和相互矛盾的研究结果，这使得难以就将SMF和EMF作为改善作物生长和产量的可持续替代方法的潜在用途得出客观结论。考虑到环境中它们来源的丰富性，了解将植物暴露于SMF和EMF的任何不利影响同样至关重要。为了更连贯地概述植物如何响应暴露于SMF和EMF，不仅包括其在农艺重要性方面观察到的影响，还包括SMF和EMF在植物细胞中的作用机制，我们编制了一份系统图。
将通过使用从研究问题的人群、暴露和结果参数中获得的术语搜索六个书目数据库和三个基于网络的搜索引擎来识别文献。发表在同行评审期刊上的原始研究和灰色文献将作为证据图的来源。符合纳入条件的研究可能包括：暴露于SMF或非电离EMF的粮食作物和相关研究模式植物；除粮食作物收获后改良外的所有植物发育阶段的处理；以及对照组的存在。符合条件的文献将在标题、摘要和全文层面进行筛选。证据图不会对研究的有效性进行严格评估。将对符合条件的文献进行相关信息的双重提取和编码过程。在证据图中，相关数据将以文本、图表、表格和图形的形式呈现。这将说明研究趋势，使关于有足够发现的集群和重大差距领域的证据基础更加清晰，并为利益相关者在研究规划和政策制定的决策提供信息。
