为探讨接种根瘤菌对Cd胁迫下紫花苜蓿氮代谢的影响，采用盆栽试验，以2种紫花苜蓿（维多利亚、WL525HQ）为植物材料，研究Cd（0 mg·kg-1和50 mg·kg-1）处理土壤接种根瘤菌对两种紫花苜蓿的氮代谢关键酶活性和含氮化合物的影响。结果表明，Cd胁迫影响紫花苜蓿氮代谢，50 mg·kg-1 Cd胁迫对未接种根瘤菌紫花苜蓿WL525HQ地上部硝酸还原酶（NR）活性的影响最大，NR活性较0 mg·kg-1 Cd处理降低85.01%。0 mg·kg-1 Cd处理时，WL525HQ接种根瘤菌后地上部谷氨酸合成酶（GOGAT）活性较未接种组提高95.53%，维多利亚接种根瘤菌后地上部天冬酰胺合成酶（AS）活性增加33.30%。50 mg·kg-1 Cd胁迫时，与不接种根瘤菌相比，接种根瘤菌的W...
