In this research, we evaluated the effects of plant age on arsenic accumulation by arsenic hyperaccumulator Pteris vittata after growing in an arsenic-contaminated soil for 8 weeks. The study used a completely randomized design consisting of four plant ages (2, 4, 10 and 16 months) with four replications each. While the fronds of the 2 month old plants contained 36% more arsenic than those of the 4 and 16 month old plants, they were lower in roots. After 8 weeks of growth, the final frond biomass increased by 39, 6.9, 2.0 and 1.1 times compared to the initial frond biomass, from youngest to oldest, respectively. Higher phosphorus and iron accumulation in the roots of older plants may have affected the plant’s efficiency to bioconcentrate and transfer arsenic from the roots to the fronds. Greater metabolic activity and higher rate of biomass production lead to higher As accumulation and removal by young plants. This research demonstrated that the use of young plants can be an effective strategy to reduce the time to remediate an As-contaminated site.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-01-13T13:24:39Z No. of bitstreams: 1 art%3A10.1007%2Fs11270-007-9485-y.pdf: 270534 bytes, checksum: 420cfc37cce33c369a3fbb4d22e1d724 (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2014-09-09T14:57:41Z (GMT) No. of bitstreams: 1 art%3A10.1007%2Fs11270-007-9485-y.pdf: 270534 bytes, checksum: 420cfc37cce33c369a3fbb4d22e1d724 (MD5)Made available in DSpace on 2014-09-09T14:57:42Z (GMT).
