Abstract While the impacts of microplastics on aquatic and agricultural ecosystems are well studied, forest involving soil trees scarcely investigated. Here, we assessed microplastic addition rhizosphere properties, chemical, morphological anatomical traits fine roots for ectomycorrhizal (ECM) arbuscular mycorrhizal (AM) tree species in a mixed temperate forest. We found that concentration available nitrogen increased, while phosphorus decreased ECM after microplastics. The opposite pattern was true AM species. Fine exhibited shorter root length, smaller diameter, lower tissue density, branching ratio, intensity, concentration, but higher hyphal carbon/nitrogen, carbon/phosphorus ratios with mediated by total soil. specific tip epidermal thickness, vascular bundle diameter carbon/nitrogen cortical density addition, which water content, nitrate phosphorus. These findings mycorrhizal-specific responses to will deepen our understanding carbon nutrient cycling composition dynamics increasing pollution ecosystems.
