Effect of Arbuscular Mycorrhizal Fungi on Antimony Uptake and Antioxidative Responses of Medicago Sativa in Antimony Polluted Soil
摘要
Abstract
Under greenhouse pot experiment conditions, mixed arbuscular mycorrhizal(AM)fungi(Funneliformis mosseas and Glomus versi-forme)were inoculated on Medicago Sativa(M. sativa), and the effects on the biomass, accumulation of antimony(Sb)and antioxidant en-zyme system of the plant were investigated. The experiments were conducted using soil treated with Sb at 0, 500 and 1000 mg·kg-1. The re-sults indicated that the inoculation greatly promoted the accumulation of Sb in M. sativa. Compared to the non-inoculated treatment, the Sb concentrations in the shoots and roots of M. sativa increased 71%and 46%under 500 mg·kg-1 Sb-treated soil, and 37%, 34%under 1000 mg·kg-1 Sb- treated soil, respectively. Inoculation also significantly enhanced the adsorption of phosphorus(P)in M. sativa, which may induced higher biomass of the plant. Meanwhile, Inoculation reduced the peroxidase(POD), superoxide dismutase(SOD)and catalase (CAT)activities in M. sativa. In conclusion, M. sativa inoculated with arbuscular mycorrhizal fungi were less sensitive to Sb stress than uninoculated plants. This results suggested that AMF play an important role in the uptake of Sb by plant, and also its resistance to Sb.关键词
