There are few reports on the use of arbuscular mycorrhizal fungi (AMF) to promote growth and stress tolerance of soybean (Glycine max L.) in agricultural soils contaminated with heavy metals. The present study evaluated the role of AMF in promoting tolerance and growth, as well as uptake of heavy metals in shoots of soybean plants. Soybean plants were inoculated with AMF (Funneliformis mosseae) in a pot experiment polluted with different concentrations of heavy metals [copper (Cu), lead (Pb) and zinc (Zn)] as well as their combination. The tested AMF inoculum promoted the soybean growth and seed yield. Increased colonization of the soybean roots improved the soybean growth through increased phosphorus uptake and accumulation in the plant tissues by 68.8%. The results showed that soybean grown in the contaminated soils inoculated with AMF were more tolerant in alleviating the metals toxicity by retaining the heavy metals in the roots, thereby reducing translocation of Cu, Pb and Zn by 21.8, 57.6 and 67.3% respectively in the aerial part of the plant and improving the overall plant productivity by 59.1%. The findings provide evidence of the potential of AMF in phytoremediation of agricultural soils contaminated with toxic metals.

关于使用丛枝菌根真菌（AMF）促进重金属污染的农业土壤中大豆（Glycine max L.）的生长和胁迫耐受性的报道很少。本研究评估了AMF在促进大豆幼苗的耐受性和生长以及摄取重金属中的作用。用AMF（Funneliformis mosseae）接种大豆植物。）在盆栽实验中受到不同浓度的重金属[铜（Cu），铅（Pb）和锌（Zn）]及其组合的污染。经测试的AMF接种物可促进大豆生长和种子产量。大豆根部定植的增加通过植物组织中磷的吸收和积累增加了68.8％，从而改善了大豆的生长。结果表明，在接种了AMF的污染土壤中种植的大豆更能耐受金属毒性，方法是将重金属保留在根中，从而使土壤中的Cu，Pb和Zn转运分别降低21.8％，57.6％和67.3％。部分工厂，使整个工厂的生产率提高了59.1％。该发现提供了AMF在被有毒金属污染的农业土壤的植物修复中的潜力的证据。
