摘要：

A novel highly sensitive electrochemical carboxymethylcellulose-gelatin-superoxide dismutase biosensor was used for the determination of superoxide radicals enhancement in tomato plants exposed to salinity, drought, cold and heavy metal stress. The variations in superoxide radicals depending on abiotic stress was determined using biosensor. The superoxide radical production with regard to control rapidly was increased in tomato plants exposed to salinity, drought, cold and heavy metal stress. The superoxide radical enhancement in tomato plants exposed to salinity, drought, cold and heavy metal stress was successfully determined using carboxymethylcellulose-gelatin-superoxide dismutase biosensor.
