The incidence of arbuscular mycorrhizal (AM) and response to inoculation of 81 native woody species from Tibagi river basin, Paraná State, South Brazil, under greenhouse conditions are reported. The AM colonization incidence of 51 native woody species collected in the area at the beginning of arboreal succession and in the interior of the forest of the Parque Estadual Mata dos Godoy (23° 27' S e 51o 15' W) is also analysed. The response to inoculation and AM colonization in greenhouse were in general high between the pioneer and early secondary species, and low between the late secondary and climax species. In nine arboreal species belonging to the late secondary and climax species did not show response to inoculation. The incidence of AM colonization in root samples collected in the field was high to intermediate among the pioneer and early secondary species and was low to very low between the late secondary and climax species. Peltophorum dubium (canafístula), Zeyheria tuberculosa (ipê-felpudo) e Aspidosperma polyneuron (peroba-rosa) did not have response to inoculation and AM colonization of the roots from both the greenhouse and field. All other species showed AM colonization which changed from very high to very low, indicating that the occurrence of AM colonization is generalized among native woody species. The woody species belonging to the early phases of succession were more susceptible to AM symbiosis than later successional species.
