Arbuscular mycorrhizal fungi (AMF) establish symbiotic relationships with plant roots, which aids the growth and development of host plants, as well as their ability to resist external biotic and abiotic stresses. AMF are thus an important soil microbial resource. Here, recent research progress on the role of AMF in promoting the vegetative and reproductive growth, yield quality, stress physiology, and disease resistance of horticultural plants (fruit trees, vegetables, flower crops, and ornamental plants) within and outside of China is reviewed. Application of various chemicals such as strigolactone, polyamine, dopamine, melatonin, and biochar, and soil microorganisms such as mycorrhizal helper bacteria and plant rhizosphere bacteria can also amplify the positive effects of AMF on host plants. AMF improve the nutrient and water supply of horticultural plants, increase their yield and quality, and enhance their tolerance of environmental stress and resistance to pathogens. The efficacy of combining AMF application with other compounds and rhizosphere microorganisms for improving the yield and quality of horticultural crops under different types of stress is also discussed.

丛枝菌根真菌（AMF）与植物根系建立共生关系，有助于寄主植物的生长发育，以及它们抵抗外部生物和非生物胁迫的能力。因此，AMF 是一种重要的土壤微生物资源。本文综述了近年来国内外关于AMF在促进园艺植物（果树、蔬菜、花卉、观赏植物）营养和生殖生长、产量品质、胁迫生理和抗病性等方面的研究进展。 . 应用各种化学物质，如独脚金内酯、多胺、多巴胺、褪黑激素和生物炭，以及土壤微生物如菌根辅助细菌和植物根际细菌，也可以放大 AMF 对寄主植物的积极作用。AMF改善园艺植物的养分和水分供应，提高其产量和品质，增强其对环境胁迫的耐受性和对病原体的抵抗力。还讨论了将 AMF 应用与其他化合物和根际微生物相结合在不同类型胁迫下提高园艺作物产量和质量的效果。
