利用温室盆栽试验,研究了不同锑浓度(0、500、1000 mg·kg~(-1))土壤处理下混合接种丛枝菌根(Arbuscular mycorrhizal,AM)真菌(Funneliformis mosseas 和Glomus versiforme)后对苜蓿(Medicago Sativa)的锑累积量、生物量和抗氧化酶活性的影响。结果表明:接种AM 真菌显著促进了苜蓿对锑的积累。在土壤锑浓度为500 mg·kg~(-1)时,接种AM 真菌地上和地下部分锑含量分别增加了71%和46%;在锑浓度为1000 mg·kg~(-1)时,地上和地下部分锑含量增加了37%和34%。在土壤锑胁迫条件下,接种AM 真菌能显著提高苜蓿地上部分对磷的吸收,这可能是苜蓿生物量增加的原因。同时,接种处理降低了苜蓿中超氧化物歧化酶(...

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 t...
