摘要：

<正>The acute toxicity of Sodium dodecylbenzene sulfonate (SDBS) to subcamersed macrophyte Hydrilla verticillata (L.f) Royle was studied.Chlorophyll contents and the activities of 3 antioxidant enzymes: superoxide dismutase (SOD,EC 1.15.1.1),catalase (CAT,EC 1.11.1.6),peroxidase (POD,EC 1.11.1.7) in the leaves were investigated under different concentrations of SDBS,The chlorophyll contents in leaves of experimental plants decreased gradually,while the electrical conductivity of culture solution increased gradually with the increased dose of SDBS.Under higher concentrations of SDBS (32 mg/L and 128 mg/L) treatment,SOD lost its activities completely after 24 h.The native PAGE analysis indicated the diversity of POD isoenzymes was obvious under different concentrations of SDBS stress.
