This study reports the percentage of mycorrhizal colonization, as well as the spore density of arbuscular mycorrhizal fungi in Paepalanthus bromelioides (Eriocaulaceae) and Bulbostylis sp. (Cyperaceae) in southeastern Brazil. Soil and root samples were collected in 2006. Spores of arbuscular mycorrhizal fungi were analyzed for species identification and roots samples for mycorrhizal colonization. Both plant species were mycotrophic showing arbuscular mycorrhizal fungi. Three genera of arbuscular mycorrhizal fungi found in rooting-zone soils were Glomus (two species), Acaulospora (one species) and Scutellospora (one species). Glomus was the dominant genus, and G. brohultii was the most common species. The average spore density of arbuscular mycorrhizal fungi was 77-139 per 100 g dry soil, and the richness was 3 to 4 species of arbuscular mycorrhizal fungi per sample. Both plant species showed high rhizosphere spore densities, and dominant hyphae and vesicle colonization. The diversity of arbuscular mycorrhizal fungi was found to be low. In P. bromelioides roots only hyphae and vesicles were observed. |
