摘要Heavy metal pollution of the soil has become a global threat to the terrestrial environment, food security, and human health due to their non-biodegradable and high persistent characteristics in the soil. However, the effective measurements for the restoration of these polluted soils are rare; therefore, this study was conducted to investigate the role of four naturalized plants (Celosia argentea, Praxelis clematidea, Eupatorium adenophora, and Solidago canadensis) as potential resources for the remediation of cadmium contamination through a tolerance and accumulation experiment. The plants' morphological phenotype (growth and biomass), physiological phenotype (relative chlorophyll content, leaf nitrogen content, root cell activity, and reactive oxygen species), and cadmium accumulation were evaluated using the hydroponic method. The results showed that cadmium induced an excess of reactive oxygen species in the roots, and the growth of C. argentea is depressed greatly. Praxelis clematidea, E. adenophora, and S. canadensis were identified to have a higher tolerance to cadmium accumulation and could be used as potential species for phytoremediation after further investigation of the actual remediation results in the field.
