Abstract Ectomycorrhiza (ECM) plays an important role in plant nitrogen (N) nutrition and regulates responded to climate warming. We conducted a field experiment natural forest plantation the eastern Tibetan Plateau estimate warming effects of open-top chambers (OTC) on ECM N Picea asperata seedlings. Four-year significantly decreased colonization, fungal biomass, fine root vigor concentration leaf, stem coarse root, but increased content stem, whole forest. Contrarily, induced no obvious change most these parameters plantation. Moreover, rhizospheric soil inorganic both forests. Our results showed that four-year was not beneficial for colonization P. seedlings two forests were more sensitive flexible experimental than The changes biomass effective uptake would be good growth remit leaching under future
