Resumen:
The endomycorrhizal fungal colonization in roots and the spore number in the rhizosphere were cuantified in three grazing situations during summer and winter in a mountane grassland of Córdoba, Argentina.The roots colonization in summer were higher than in winter and the herbivory increased it. The spore number were not modified by grazing but were influenced by host metabolic (C3/C4)and host species. Several Poaceae were recorded as new host: Agrostis pyrogea,Briza subaristata,Deyeuxia hieronymi, Festuca tucumanica, Melica stuckertii, Muhlembergia peruviana, Sorghastrum pellitum, Stipa nidulans and Vulpia myurus as host, enlarged its distribution. Alchemilla pinnata (Rosaceae) is also a new host.
