ABSTRACT = {<i>Entoloma clypeatum</i>, a kind of edible ectomycorrhizal fungus, can be usually symbiotic with Rosaceae fruit trees. Fruit trees have become an important part of China’s agriculture. The present work focused on exploring how <i>E. clypeatum</i> affected symbiotic Rosaceae plants and establishing a symbiotic culture with <i>Malus robusta, Pyrus betulifolia</i> and <i>Prunus armeniaca</i> rootstocks. The results showed that <i>E. clypeatum</i> and three Rosaceae plants can generate cylindrical or clavate mycorrhizae. The inoculation treatment had different degrees of positive effects on the three plants. Relative to the non-inoculated group, biomass in symbiotic plants increased (32.8%–191.1%), and photosynthesis enhanced. In the level of plant endogenous hormones, the concentration of zeatin, auxin and gibberellin increased (45.45%–228.95%), and the concentration of abscisic acid decreased (35.99%–76.21%). In roots and leaves of plants, the activities of antioxidant enzymes increased (19.0%–249.8%), soluble sugar, soluble protein and free proline concentrations increased (24.9%–373.3%), and the concentration of malondialdehyde decreased (43.6%–79.1%). According to these findings, <i>E. clypeatum</i> stimulated the growth of <i>M. robusta</i>, <i>P. betulifolia</i> and <i>P. armeniaca</i> and improved stress tolerance and adaptability. Our study provides a basis for developing and applying <i>E. clypeatum</i>, facilitates fruit tree industry development and serves as a resource for studying ectomycorrhizal fungi.},
