英文摘要	Although it is known that the first As hyperaccumulator identified, Pteris vittata L., could exist in As-contaminated as well as uncontaminated soils, intra-specific variation in As accumulation among metallicolous (from As-contaminated soils) and nonmetallicolous populations (from uncontaminated soils) of P. vittata has not been fully explored. Variations in As concentrations of fronds were observed in three nonmetallicolous populations and four metallicolous populations of P. vittata collected from southeast China. The kinetics study showed that the concentration-dependent influx of arsenate and arsenite observed followed Michaelis-Menten kinetics, and that the average V (max) for arsenate and arsenite was apparently larger in the three nonmetallicolous populations than that in the three metallicolous populations. The pot trials indicated that the nonmetallicolous populations had significantly (p < 0.05) higher frond biomass, about 1.5-1.9-folds, when compared with the metallicolous populations in 250 and 500 mg As kg(-1) soil treatments. The pot trials also demonstrated that the nonmetallicolous population of P. vittata had a significantly higher accumulation and translocation capacity for As. The present study suggests that As removal by P. vittata can be greatly enhanced by the judicious selection of the appropriate populations.
