The application of arbuscular mycorrhizal (AM) fungi has been reported to confer multiple agronomic benefits to crop plants including cereals, vegetables, and fruit trees, as well as to improve soil structure and health. In this study, we conducted a meta-analysis to investigate whether AM fungal addition enhances potato yield. We further examined whether several experimental conditions (type of experiment, inoculation method, and source of AM fungi) and potato cultivar may explain the outcomes. We calculated the effect sizes of seven plant parameters by including a total of 106 independent pot and field experimental studies from 37 peer reviewed publications. Our results show that the addition of AM fungi has an overall positive effect on all potato plant parameters included in our analyses except for aboveground plant biomass. Potato cultivar was the main significant moderator explaining our findings, with some cultivars benefiting more from AM fungal presence than others. Our findings agree with several other global meta-analyses reporting positive effects of AM fungi on other important crops and highlights the potential application of these fungal symbionts in potato agro-ecosystems.
据报道，丛枝菌根（AM）真菌的应用能给包括谷类、蔬菜和果树在内的作物带来多种农艺效益，还能改善土壤结构和健康状况。在本研究中，我们进行了一项荟萃分析，以调查添加AM真菌是否能提高马铃薯产量。我们还进一步研究了几个实验条件（实验类型、接种方法和AM真菌来源）以及马铃薯品种是否能解释实验结果。我们通过纳入来自37篇同行评审出版物的总共106项独立盆栽和田间实验研究，计算了七个植物参数的效应大小。我们的结果表明，添加AM真菌对我们分析中包括的所有马铃薯植株参数都有总体积极影响，但地上部植株生物量除外。马铃薯品种是解释我们研究结果的主要显著调节因素，一些品种比其他品种从AM真菌的存在中受益更多。我们的研究结果与其他几项全球荟萃分析一致，这些分析报告了AM真菌对其他重要作物的积极影响，并突出了这些真菌共生体在马铃薯农业生态系统中的潜在应用。
