[目的]研究丛枝菌根真菌对 Cu、Pb处理下旱稻氧化胁迫的影响。[方法]采用盆栽实验的方法，以旱稻为研究材料，研究了丛枝菌根真菌对不同土壤Cu浓度（0、100、200 mg/kg）、Pb浓度（0、300、600 mg/kg）处理下旱稻地上部分生理抗性影响。[结果]与未接种处理相比，接种处理抑制100 mg/kg Cu、300 mg/kg Pb处理下 POD、CAT以及 SOD活性，但是显著提高可溶性蛋白含量。200 mg/kg Cu处理下，接种处理抑制 SOD活性却提高 POD、CAT活性和可溶性蛋白含量。600 mg/kg Pb处理接种处理下 SOD、POD活性与未接种处理无显著区别，但是显著抑制 CAT活性以及降低可溶性蛋白含量。以上结果说明，在不同的Cu、Pb浓度处理下，丛枝菌根真菌对旱稻体内的酶活性以及可溶性蛋白影响不同，因而对于重金属引起的旱稻地上部分氧化胁迫的影响程度不同。[结论]该研究可为土壤重金属污染的生物修复提供理论参考。

[Objective] This study aimed to investigate the effect of arbuscular mycor-rhizal fungi on upland rice oxidative stress induced by Cu and Pb contamination in soil. [Method] The upland rice seeds were sowed in pots, in which the soil was previously mixed with a certain amount of Glomus mosseae and 0, 100 and 200 mg/kg Cu, or 0, 300 and 600 mg/kg Pb. In the control treatment, Glomus mosseae was inactivated before mixed into the soil. Then, the physiological and chemical properties of the aboveground parts of rice plants were measured at mature stage. [Result] Compared with the control treatment (NM), Glomus mosseae (GM) treat-ment inhibited the POD, CAT and SOD activity while increased the soluble protein content under 100 mg/kg Cu and 300 mg/kg Pb treatment, improved the POD and CAT activity and soluble protein content while decreased SOD activity under 200 mg/kg Cu. SOD and POD activity showed no significant difference between NM and GM treatment under 600 mg/kg Pb, but the CAT activity was enhanced and soluble protein content was decreased. [Conclusion] This study wil provide theoretical refer-ence for bioremediation of soil heavy metal pol ution.
