Natural saline soils of Central Argentina have rarely been the focus of arbuscularmycorrhizal fungi (AMF) which are Glomeromycota. We explored the vertical distributionof spores of different AMF species in the rhizosphere of Atriplex lampa in two saline environments(Salinas Grandes and Salinas de Ambargasta) during wet and dry seasons.18 AMF species were identified. Spore numbers were highest at Salinas Grandes during thewet season. Soil depth showed an influence on spore abundance of some specific species.Our results highlight the effect of soil depth, seasons and soil characteristics on sporulationof AMF species under saline conditions.
