Abstract

The elemental composition of spore wall of arbuscular mycorrhizal fungi (AMF) was analyzed by energy-dispersive X-ray spectrometry (EDS) in a preliminary assessment. Measurements of AMF spores were made for riparian soils in both urban (rivers subjected to different human activities) and farm sites in southeastern Brazil. Spore populations belonging to four genera: Acaulospora,GigasporaGlomus and Scutellospora were analyzed. The results suggest that Glomeraceae spores sequester more elements than Acaulosporaceae and Gigasporaceae; however, the presence of nickel was observed in oneScutellospora species. These data showed the elements sequestered by AMF spores in riparian sites presenting different conditions of disturbance.

 

Key words: Arbuscular mycorrhizal spores, urban sites, energy-dispersive X-ray spectrometry, riparian forest.
