The effects of different electrode on Solanum nigrum L.seed germination were determined.The result showed that germination percentage (GP) of seeds in treatment T2 (titanium elec-trode) was 26.6％ higher than in control (CK,without electric field).High potassium and calcium concentrations were beneficial for seed enzymatic activity in treatment T2,which could partly explain the increase in GP.Cd accumulation (μg/pot) in S.nigrum treated with any electric field was significantly higher (p＜0.05) than in CK without electric field.Specif-ically,Cd accumulation under the treatment T3 (stainless steel electrode) was the highest both in roots and shoots;this accumulation in shoots and roots were 74.7 ％ and 67.4 ％higher for stainless steel than in CK.This increase must have been associated with a higher Cd concentration in plants and did not exert a significant effect on the biomass.In par-ticular,Cd concentrations in roots and shoots under stainless steel treatment were both significantly higher than in CK (p＜0.05),which had to be related to the higher available Cd concentration in the soil in the middle region.Furthermore,it could be attributed to al-tered soil pH and other soil properties.Moreover,none of the biomasses were significantly affected (p＜0.05) by different electrode materials compared to CK.
