| Abstract: | Callus of Alternanthera philoxeroides was cultured by tissue culture technique,which was used as experimental material.This paper studied the toxic effects of Pb2+ gradient concentrations(0,0.2,0.4,0.8 and 1.6 mmol/L) on the contents of photosynthetic pigments and soluble protein,the level of active oxygen,activities of antioxidase(CAT,SOD and POD) and changes of ultrastructure in callus of Alternanthera philoxeroides.The results indicated that,with the increasing of Pb2+ concentration,the contents of photo... |
