In some saline areas, pollutants such as heavy metals have been spread due to industrial activities. halophyte plants can be useful for phytoremediation of such areas. To investigate the effect of salinity and heavy metal copper and their interaction effect on the halophyte plant Bassia Scoparia L. two factorial experiments were conducted in a completely randomized design in Hydroponics laboratory of Birjand University. In the first experiment, separate and interaction effects of five levels of salinity (0, 100, 200, 300, and 400 mM) and five levels of copper (0, 50, 100, 200, and 300 mg/L) on the germination characteristics of B. Scoparia seeds were measured. Results of this experiment showed that the increase in salinity and copper has a significant negative effect on the germination and growth of seedlings. In the second experiment, effect of three levels of salinity (0, 100, and 300 mM) and three levels of copper (0, 50, and 100 mg/L) in pot culture on the traits related to growth and amount of sodium and copper in roots and shoot was investigated. Salinity significantly increased the amount of sodium in roots and shoots but did not affect the amount of copper in roots and shoots. Under treatment of copper, amount of this metal increased in roots and shoots of B. Scoparia. However, by having accumulation factors of less than one, B. Scoparia does not seem suitable for plant extraction of copper, although it can be used to stabilize this metal by having a suitable biomass and considerable absorption of copper in root.
