Potential contribution of arbuscular mycorrhiza to cadmium immobilisation in soil

Original language description

The contribution of arbuscular mycorrhiza (AM) to immobilisation of Cd in substrate was studied in two experiments. In the first experiment, substrates prepared by cultivating tobacco, either non-mycorrhizal or inoculated with the AM fungus Glomus intraradices were enriched with a range of Cd concentrations, and Cd toxicity in the substrates was assessed using root growth tests with lettuce as a test plant. The tests revealed lower Cd toxicity in the mycorrhizal than in the non-mycorrhizal substrate, and the difference increased with increasing total Cd concentration in the substrates. In the second experiment, extraradical mycelium (ERM) of G. intraradices exposed in vivo to Cd was collected and analysed on Cd concentration. The ERM accumulated 10?20times more Cd per unit of biomass than tobacco roots. While Cd concentrations were lower in the biomass of mycorrhizal plants than of non-mycorrhizal plants, Cd immobilisation by ERM did not affect the total Cd content in mycorrhizal toba
