Recebido em 11/5/11; aceito em 18/10/11; publicado na web em 4/1/12 TROPICAL PTERIDOPHYTES SPECIES IN ASSOCIATION WITH ARBUSCULAR MYCORRHIZAL FUNGI IN ARSENIC-CONTAMINATED SOIL. The symbiosis of plants with mycorrhizal fungi represents an alternative to be considered during the processes of revegetation and rehabilitation of arsenic-contaminated soil. The aim of this study was to evaluate under greenhouse conditions the effect of arsenic on the mycorrhizal association of two species of tropical

T. salzmannii had higher rates of colonization and higher density of spores while D. flexuosa showed greater sensitivity to smaller concentrations of arsenic and association with mycorrhizal fungi. Our results indicate that screening and selection of mycorrhizal fungal isolates/species is possible and effective for phytoremediation of arsenic-contaminated soils.
