Abstrakt: In this study, phytoremediation potential of toxic metals like selenium (Se) and lanthanum (La) by transformed hairy roots was investigated and compared with plantlets under in-vitro conditions. Agrobacterium rhizogenes A4RS could induce hairy roots with higher biomass in 5-7 days of infection on in-vitro leaves of Hybanthus enneaspermus. The ICP-OES data indicated that the hairy roots were able to accumulate both selenium and lanthanum efficiently compared to plantlets. The hairy roots and plantlets show optimum absorption at 50 ppm under both individual and combined metal supply. The metal accumulation performances increased by 13.6% (La) and 10.9% (Se) in hairy roots with combined metal supply (La and Se) compared to individual supply (La or Se) conditions. The Se accumulated more than La, but the La accumulation percentage was found to increase substantially under combined metal supply conditions, shows the suitability and potential of hairy roots for phytoremediation of La and Se.
