title: Genotypic variation in phytoremediation potential of Indian mustard exposed to nickel stress: a hydroponic study.
abstract: Ten Indian mustard (Brassica juncea L.) genotypes were screened for their nickel (Ni) phytoremediation potential under controlled environmental conditions. All ten genotypes were grown hydroponically in aqueous solution containing Ni concentrations (as nickel chloride) ranging from 0 to 50 μM and changes in plant growth, biomass and total Ni uptake were evaluated. Of the ten genotypes (viz. Agrini, BTO, Kranti, Pusa Basant, Pusa Jai Kisan, Pusa Bahar, Pusa Bold, Vardhan, Varuna, and Vaibhav), Pusa Jai Kisan was the most Ni tolerant genotype accumulating up to 1.7 μg Ni g(-1) dry weight (DW) in its aerial parts. Thus Pusa Jai Kisan had the greatest potential to become a viable candidate in the development of practical phytoremediation technologies for Ni contaminated sites.
