Heavy metal content and localization in mycorrhizal Euphorbia from zinc wastes in southern Poland

摘要

Arbuscular mycorrhizal(AM) development, heavy metal uptake by the plant and localization of heavy metals within plant and AM fungal structures, has been investigated in Euphorbia cyparissias collected from zinc wastes on Poland and from two other stands differing in soil parameters. The plant was selected on the basis of preliminary research on mycorrhiza of plants colonizing zinc wastes. E. Cryparissias was strongly mycorrhizal and arbuscules were abundant except at the very beginning of the vegetation period. Light microscopy after rhodizoniate staining and SEM equipped with an DES system have been used to localize heavy metals within the fungal mycelium and mycorrhizal roots.
