Interactions of mycorrhizal fungi with Pteris vittata (Ashyperaccumulator) in Ascontaminated soils

摘要：

A greenhouse trial was conducted to investigate the role of arbuscular mycorrhizas (AM) in aiding arsenic (As) uptake and tolerance by Pteris vittata (As hyperaccumulator). Plants inoculated with living or killed native mycorrhizal fungi isolated from an As mine site were grown in a sterile and slightly acidic soil. The average biomass of shoots in infected P. vittata increased according to the increase of As levels when compared to the control. The indigenous mycorrhizal fungi enhanced As accumulation in the As mine populations of P. vittata and also sustained its growth by aiding P absorption.
