  P. crispus grew better in Taihu Lake sediment when compared with that in Yuehu lake sediment;P. crispus grew worst in Tangxunhu Lake sediment. There were significant differences for shoots biomass,roots biomass,propagules biomass and germination rates in different sediments.3) By the study of P. crispus growth in sediment of different sites in Taihu Lake and Yuehu Lake, it was found that flourish shoots growth would be helpful for the generation of propagules of P. crispus,although there was no corresponding relationship between germination rates of propagules with P. crispus growth.
