%X Artemisia selengensis grown in Dongting Lake wetland was recently found as a plant with good capacity in enriching Cd. A pot experiment was conducted to study the biological traits and the Cd accumulation characteristics of Artemisia selengensis to Cd stress during its growth period. The final results showed that the leaves were injured apparently in response to significant decrease of above-ground biomass when Cd concentrations in soil were higher than 40 mg·kg-1. Artemisia selengensis could complete its life cycle at a high Cd concentration (100 mg·kg-1) and showed strong resistence to soil Cd. The bioavailable Cd accounted for 15.3%~37.1% of total soil Cd. There were no significant differences of Cd concentrations in the plants during their different growth phases, but a lower Cd accumulation was observed in stems and leaves at the seedling stage than the other stages because of low biomass. During the adult stage of Artemisia selengensis, Cd accumulation was up to 492~588 mg·kg-1 under the Cd treatment of 40~60 mg·kg-1. These data suggested that Artemisia selengensis was an outstanding species that could be selected as a potential candidate to repair Cd pollution from lake soil.
