Abstract :In this study, ecotoxicological and ecophysiological effects of some different heavy metal compounds insert ignore into journalissuearticles values(CdCl2, PbCl2, and CuCl2); on Salvia candidissima subsp. occidentalis Hedge insert ignore into journalissuearticles values(Lamiaceae); were examined. Seeds of this plant were exposed to three different concentrations of CdCl2 insert ignore into journalissuearticles values(2, 6, 10 ppm);, PbCl2 insert ignore into journalissuearticles values(50, 100, 500 ppm);, and CuCl2 insert ignore into journalissuearticles values(20, 60, 150 ppm);. The results indicated that increasing CdCl2 and PbCl2 concentrations had no specific inhibitory impacts on seed germination rates, growth performance, biomass, and seedling vigor index, but increasing concentrations of CuCl2 had significant inhibitory effects on these parameters. The metal tolerance index of all applications showed that all heavy metal treatments reduce this value.
