摘　　要：用人工配制不同浓度的含萘废水培养菖蒲,比较了其根部和叶片中超氧化物歧化酶(SOD)活性、过氧化物酶(POD)活性和过氧化氢酶(CAT)活性的变化。结果表明:随着萘浓度的提高,菖蒲根部SOD活性显著下降,而叶片SOD活性极显著上升;根部POD活性上升不明显,但叶片POD活性极显著下降;根部和叶片CAT活性极显著或显著下降。菖蒲不同部位的不同抗氧化保护酶对萘污染的反应各不相同,叶片的反应要比根部更显著。Acorus calamus L.were cultured with synthetic wastewater containing different concentration of naphthalene.The activities of SOD,POD and CAT in root and leaf were compared.The results showed that,with the increase of concentration of naphthalene,the SOD activity in root decreased significantly,while the SOD activity in leaf increased extremely significantly,the POD activity in root didn＇t increase obviously,while the POD activity in leaf decreased extremely significantly,CAT activity in root and leaf decreased extremely or significantly.Different protecting enzymes of antioxidant system in different part of A.calamus had different response to naphthalene pollution,and the leaf responed more obviously than root.
