In Potamogeton crispus, the content of abscisic acid was found higher than Myriophyllum heterophyllum before treatment of cadmium. It was observed that the content of abscisic acid increased with increased in cadmium concentration (0, 4, 8, 16, 32 and 64 mg L-1) and time period (24 and 96 h) in both of species. The content of abscisic acid increased by salinity like the treatment with Cd. When the effects in combination of cadmium and salinity were considered, it was found that the content of abscisic acid increased with increased in cadmium at 0.05‰ NaCl but decreased at 5‰ NaCl. In the both species, the highest content of abscisic acid was observed in 64 mg L-1 Cd +0.05‰ NaCl at 96 h.enCadmiumAbsicisic acidAquatic plantsNaClArticle10.3923/ijb.2008.104.1082-s2.0-39749198279
