为了探讨AM(arbuscular mycorrhizal,丛枝菌根)真菌在Sb(锑)胁迫下对农作物生长及吸收Sb的影响,采用盆栽试验研究了在不同Sb添加量〔即w(Sb)分别为0、500、1 000 mgkg〕下,接种AM真菌对玉米植株生物量以及N、P和Sb的吸收、膜脂过氧化〔MDA(丙二醛)〕和抗氧化酶活性的影响.结果表明:随着土壤中Sb添加量的增加,玉米植株的生物量、w(TN)和w(TP)均呈显著下降趋势,植株体内的w(Sb)和Sb积累量、MDA含量、CAT(过氧化氢酶)以及POD(过氧化酶)活性均显著上升.与未接种组相比,接种AM真菌显著促进了玉米植株的生长,提高了玉米植株地上部分的w(TN)和w(TP).在3个Sb添加量处理下,接种显著增加了玉米植株地下部...

A pot experiment was conducted to investigate the effects of arbuscular mycorrhizal (AM) fungi on the growth and uptake of antimony (Sb) in plants under Sb stress, based on AM fungi on biomass, nutrient uptake, Sb uptake, malondialdhyde (MDA) and antioxidant enzyme activities by maize grown in soils with different Sb levels (0, 500 and 1000 mg/kg). The results showed that the biomass and contents of TN and TP in the maize decreased significantly with the increase of Sb concentration in soil. The contents of Sb, MDA, CAT and POD in the plant als...
