“…The relationship between spore numbers and mycorrhizal colonization has been found positive by several workers (Giovannetti and Nicolson, 1983) but negative by others (Louis and Lim, 1987). Some workers have also found no relationship between mycorrhizal colonization and spore density of AMF (Diaz and Honrubia, 1994). The factors like edaphic or climatic condition; host fungus compatibility, root properties and soil microorganisms might influence the abundance of spore population and mycorrhizal associations with a particular tree species.…”

“…They were selected because, in agreement with our observations, both are mycorrhizal in natural conditions and grow naturally in heavy metal contaminated soils (Dfaz and Honrubia, 1994). Seeds of L. spartum were collected at Espinardo, Murcia (Spain) and those ofA.…”

The influence of arbuscular mycorrhizae (AM) on plant growth and Zn and Pb uptake by Lygeum spartum and Anthyllis cytisoides was studied in soils with different levels of these heavy metals. A. cytisoides is highly dependent on AM for optimal growth, while L. spartum is a facultative mycotroph.Mycorrhizal and nonmycorrhizal plants were grown in soil supplemented with 0, 10, 100 and 1000 mg of Zn kg -l soil or 0, 100 and 1000 mg of Pb kg -1 soil. Two different mycorrhizal fungi were separately studied: Glomus macrocarpum isolated from a non contaminated site and a strain of Glomus mosseae isolated from a soil contaminated with these metals. The infectivity of the fungi was not affected by the presence of Zn or Pb in the soil. In unamended soil, both fungi were equally effective in promoting plant growth, but when Zn or Pb were added to soils, G. mosseae was more efficient than G. macrocarpum in stimulating plant growth of A. cytisoides. A. cytisoides was unable to grow unless mycorrhizal. Metal addition to the soil induced a reduction in the biomass of L. spartum and of mycorrhizal A. cytisoides, and a decrease in shoot P concentration of mycorrhizal plants. The concentration of metals in the plants varied according to the amount added to the soil and to the inoculation treatment: at low doses, mycorrhizal plants showed equal or higher concentration of Zn or Pb than nonmycorrhizal ones; at higher doses, however, metal concentrations in the plants inoculated with G. mosseae were lower than those found in the corresponding controls, while the plants inoculated with G. macrocarpum showed similar (L. spartum) or even higher (A. cytisoides) levels than the controls.

“…Field investigations have indicated that mycorrhizal fungi can colonize plant roots extensively even in metal contaminated sites (Diaz and Honrubia, 1994;Gildon and Tinker, 1983;Pawlowska et al, 1996;Sambandan et al, 1992), and Zn-and Cd-tolerant fungal strains have been isolated from contaminated sites by several research groups Kaldorf et al, 1999;Weissenhorn et al, 1994). These isolates have been used in laboratory studies in which they have been shown to be capable of increasing plant growth under artificial conditions of Zn contamination compared with reference strains.…”
