Arbuscular Mycorrhizae of Leymus arenarius on Coastal Sands and Reclamation Sites in Iceland and Response to Inoculation
Abstract The occurrence of arbuscular mycorrhizae fungi (AMF) was examined in natural and reclaimed sand dunes in Iceland. On the coastal sand‐plain of Myrdalssandur no spores of AMF were found on barren sand, and very few were found in 1‐ and 5‐year‐old reclamation sites of Leymus arenarius (lymegr...
