Donghua University, Shanghai 201 20, China) Abstract The rhizospheric bact erial diversity of five plants in the const ructed w etland was studied including Canna ind ica L , Vet iv er ia z iz an io iaes , P hr ag m ites comm unis , Typ ha or ientalis P r es l. and Cyp er us alter nif ol ius by PCRDGGE. Six main bands w ere all observed on the similar DGGE profiles of the five rhizospheric soils, w hich in dicated t hat t he rhizospheric bacterial communities w ere similar among the five plants in the same const ruct ed w et land system. T herefore, it is considered what determinate thestructure of bacterial communities in constructed w et land soils isnt t he characters of the plant growing but of the w astewater treated.
