Abstract

Entoloma clypeatum, 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 E. clypeatum affected symbiotic Rosaceae plants and establishing a symbiotic culture with Malus robusta, Pyrus betulifolia and Prunus armeniaca rootstocks. The results showed that E. clypeatum 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, E. clypeatum stimulated the growth of M. robusta, P. betulifolia and P. armeniaca and improved stress tolerance and adaptability. Our study provides a basis for developing and applying E. clypeatum, facilitates fruit tree industry development and serves as a resource for studying ectomycorrhizal fungi.
