Abstract
Two Brassica species Brassica juncea and Brassica carinata of the Indian mustard, were grown in an artificially Ni-contaminated soil to study the tolerance and Ni accumulation. Chelating agent, EDTA was applied at the rosette stage for enhancing the metal uptake. Nickel concentration over almost double that in control was observed in both the species with Ni contamination along with EDTA application. Specie B. juncea appeared to be slightly more tolerant and higher accumulator of Ni. In agreement with the earlier reports, the translocation of the pollutant metal to the shoot from the root seemed to be restricted in both of Brassica species at higher rate of Ni application plus EDTA. The results of the present study indicated that B. juncea has the potential to be hyperaccumulator of Ni.
