Resumen:
The effects of saprobe fungi Aspergillus níger (341), Penicillium restrictum (512) and Trichoderma harzianum (153) isolated from soil, or their exudates on the arbuscular mycorrhizal fungi Glomus mosseae and Gigaspora rosea were studied in greenhouse and in vitro experiments. A. niger and its exudates stimulated the germination and hyphal outgrowth of G. mosseae and Gi. Rosea spores and AM colonization of roots by these and native fungi in an unsterilized soil. In contrast T. harzianum and its exudates had no effects, and P. restrictum and its exudates had no effects on spore germination or hyphal outgrowth from spores of either G. mosseae or colonization by the native AM endophytes in an unsterilized soil.
