| 英文摘要 | ObjectiveChinese brake fern(Pteris vittata L) has been identified as an arsenic(As) hyperaccumulator. The present study was conducted to obtain insight into accumulation of As and its distribution in pinnae of P. vittata L.,which provide the basis to optimize the sampling method and evaluate the phytoremediation efficiency accurately.MethodField sampling and laboratory analysis were used to research As accumulation and distribution in pinnae of hyperaccumulator P. vittata L.ResultAs concentration in pinnae varied depending on their position along the frond. As concentration in the middle pinnae accounted for 35% and 37% of the basal and top pinnae,respectively. Therefore, there was a“U”-type distribution of As concentration along the frond. For As accumulation,based on biomass and As concentration in the middle pinnae was 3.1 times and 2.8 times higher than those in the basal and top pinnae,showing a“∩”-type distribution in the high-As P. vittata.ConclusionAs concentration in the middle pinnae is low,while As accumulation was high,therefore,the basal,middle and top pinnae should be given consideration while evaluating the phytoremediation efficiency in phytoremediation projects accurately. |
