Abstract: A pot experiment was carried out to investigate the growth, accumulation and transfer of Cu and Zn in Commelina communis, which were cultivated under single and combined pollution of Cu and Zn. The results showed that, with increasing single and combined concentration of Cu and Zn, the biomass of Commelina communis initially increased and then decreased. The Cu tolerance and accumulation capacity of Commelina communis was superior to Zn. With an increasing Cu and Zn concentration, the relative electronic conductivity and malondialdehyde increased and the chlorophyll content declined. Moreover, the low concentration level of Cu and Zn had a synergistic effect, which low-dose Zn significantly facilitated the adsorption of Cu in Commelina communis. While high-dose Cu and Zn tend to antagonistic effects, causing an inhibition to Cu accumulation of plant. Comprehensively, Commelina communis was a potential hyper-accumulator for Cu and could be applied to the heavy metal contaminated environments.
