Contribution of Mycorrhizae in Phytoremediation of Lead Contaminated Soils by Eucalyptus rostrata Plants

چکیده
In a greenhouse trials, the effects of arbuscular mycorrhizae fungi (AMF) on growth and uptake of N, P, K and Pb by Eucalyptus rostrata L., grown with or without Phaseolus vulgaris, in lead (Pb) contaminated soil were investigated. Inoculation of the host plants with AMF, Glomus deserticola spores, significantly increased the dry weight, shoot length, total N, P and K as well as chlorophyll concentration in Eucalyptus. The inoculation with mycorrhizal fungi enhanced the amount of Pb absorbed and accumulated by Eucalyptus. The results showed that inoculation of the host plants with AMF protects them from the potential toxicity caused by increased uptake of Pb. At all cases, E. rostrata growth and other parameters performed better at the presence of P. vulgaris plants. It seems that arbuscular mycorrhizae has a potential in phytoremediation of the heavy metal contaminated soils, particularly in the presence of legumes.
