Resumen:
Polylepis woodlands are one of the most threatened mountain ecosystems of South America and their restoration is a high priority. In order to assess the mycorrhizal status in Polylepis woodlands of Quebrada del Condorito National Park (Córdoba Mountains, central Argentina), we examined the roots of 22 plant species, belonging to 14 families and determined morphological types of arbuscular mycorrhiza (Arum- and Paris-type) and colonization level. The 22 species presented arbuscular mycorrhizal and dark septate endophyte colonization. Different mycorrhizal structures and colonization patterns were observed although Paris-type colonization was predominant. Fourteen plant species are reported for the first time as host of arbuscular mycorrhizal fungi. We conclude that arbuscular mycorrhizal fungi and dark septate endophytes hosts are widespread in the Polylepis woodlands of Central Argentina and should receive special attention in future re-vegetation programs.
