“…The higher metal uptake cannot be attributed to mycorrhizal effects on plant growth or P accumulation, since mycorrhizal plants did not have higher dry weight or P concentration than non-mycorrhizal plants. Our findings in this salt marsh plant are in accordance with those studies in other systems reporting higher metal uptake and root accumulation due to AM colonization (e.g., Chen et al 2004;Joner and Leyval 1997;Tonin et al 2001).…”

It is known that vegetation plays an important role in the retention of heavy metals in salt marshes by taking up and accumulating the metals. In this study, we investigated whether arbuscular mycorrhizal fungi (AMF) increase Cd and Cu uptake and accumulation in the root system of the salt marsh species Aster tripolium L., and whether indigenous AMF isolated from polluted salt marshes have higher capacity to resist and alleviate metal stress in A. tripolium than isolates of the same species originated from nonpolluted sites. Plants inoculated with Glomus geosporum, either isolated from a polluted salt marsh site (PL isolate) or from a non-polluted site (NP isolate), and non-mycorrhizal (NM) plants were compared in a pot experiment at four different Cd and Cu concentrations. Cd had no effect in root colonization, whereas high concentrations of Cu decreased colonization level in plants inoculated with the NP isolate. AM colonization did not increase plant dry weight or P concentration but influenced root Cd and Cu concentrations. Inoculation with PL and NP isolates enhanced root Cd and Cu concentrations, especially at highest metal addition levels, as compared to NM plants, without increasing shoot Cd and Cu concentrations. There was no evidence of intraspecific variation in the effects between AMF isolated from polluted and non-polluted sites, since there were no differences between plants inoculated with PL or NP isolate in any of the tested plant variables. The results of this study showed that AMF enhance metal accumulation in the root system of A. tripolium, suggesting a contribution of AMF to the sink of metals within vegetation in the salt marshes.

“…In agreement with previous observations (Chen et al 2004;Biró and Taká cs 2007), we noted enhanced biomass production of AM plants in response to AMF colonization. However, the increasing Cd concentration of soils decreased the shoot dry matter of 11-and 20-week-old plants ( Table 2).…”

“…According to our results, higher Zn and Cu content could be observed in 11-week-old AM plants compared to controls, whereas these values were rather equal or lower than those of the control in the case of 20-week-old plants. Enhanced and reduced nickel (Ni) uptakes of AM plants have also been reported in previous studies (Taká cs and Vö rö s 2003b; Chen et al 2004;Biró and Takács 2007). Higher acquition rates of Ni were observed in nonmycorrhizal plants than in mycorrhizal plants harvested after 11 and 20 weeks, too.…”

Adaptability of five Glomus mosseae cultures of different origins to the soil cadmium (Cd) content and the changes of the efficiency of the symbiosis between the arbuscular mycorrhizal fungi (AMF) strains and white clover (Trifolium repens L.) hosts were investigated in a pot experiment. The parameters of mycorrhizal colonization of the different strains and efficiency such as macroand microelement content of the shoots of mycorrhizal and nonmycorrhizal plants, the plant growth response to the increasing soil Cd content (0, 50, 100 mg kg 21 ), and the response to the AMF inoculation were compared at harvesting after 11 and 20 weeks. Variability was observed in the tolerance of different G. mosseae strains to soil Cd loading. Arbuscular richness of the probable Cd-adapted strain was not influenced either by increasing soil Cd content or harvesting time, whereas that parameters of nonadapted strains showed decrease in time. The effect of different AMF inoculation on plant biomass production also varied significantly. The phytotoxicity level caused by Cd was alleviated in the case of inoculation with two strains the most. Higher acqusition of some essential macro-and microelements were observed in case of mycorrhizal plants compared to controls. The general occurence and effectiveness of G. mosseae AMF species is obviously related to intraspecific variability. The adequate selected stress-tolerant AMF strains can be useful in phytoremediation.
