I want to set up a pot experiment of which phytoremediation techniques should be used as to remove metals. So, which plant I should use or who are the most effective accumulators.
Brassica juncea is the most suitable plant for phytoremediation of heavy metals.
Hi Tamjid Us Sakib ,
Water hyacinth (Eicchornia crassipes) is a best candidate for phytoremediation of various hazardous chemicals as well as easy to maintain. Try with that. Cheers.
Manavi Ekanayake Water hyacinth may not be a great choice if Tamjid Us Sakib is trying to remediate a dryland farm soil as it grows in waterways and ponds. He lists soil science and soil chemistry as some of his interests rather than wetlands.
There are phytoaccumulators from all over the world, depending on the elements of interest. For example Ni is described in this article:Article Nickel hyperaccumulation mechanisms: a review on the current...
There is even a Wikipedia page on hyperaccumulators: https://en.wikipedia.org/wiki/Hyperaccumulators_table_–_3
Perhaps a google scholar search would help you to narrow down the elements and species that is most appropriate for your project.
water hyacinth, water lettuce, and Azolla pinnata can be used for phytoremediation of wastewater. these species is highly effective for the treatment of any kind of wastewater.
Brassica juncea is the most suitable plant for phytoremediation of heavy metals.
Brown mustard or Indian mustard wich belongs to Brassicaceae is suitable as heavy metals accumulator.
Also, water hyacinth ( Eichhornia crassipes ), the free-floating perennial aquatic plant is good plant for heavy metals accumulation such as Cadmium, Chromium and Zink.

There are various hydrophytic plant species that are suitable for heavy metal accumulation in wastewater. such as Eicchornia crassipes, Azolla pinnata, Nelumbo, Pistia, Lemna etc.
Another hydrophytic plant that is proven suitable for phytoremediation of heavy metals is the Apium Nodiflorum, especially for aqueous solutions containing Fe, Ζn, Cu, Μn.
Thus far, the majority of the plant species classified as hyperaccumulators fulfil the criteria described above. These species, however, produce little biomass and are slow-growing plants, which makes it unfeasible to use these species in phytoremediation. Nonetheless, these model organisms, which are able to accumulate extremely high concentrations of heavy metals, have been essential for studies focused on understanding the mechanisms that allow them to accumulate and tolerate phytotoxic concentrations of a wide range of heavy metals. Thus, these organisms can be used as a reference from which to develop strategies to genetically modify other plant species that have more favourable characteristics for phytoextraction, such as higher biomass production. For this reason, non-hyperaccumulator plant species should be studied for their phytoremediation potential to be understood, particularly crop plant species that have high biomass production (Peuke and Rennenberg, 2005) and are tolerant of other abiotic factors. Additional factors to consider include good growth performance in the field, little investment needed for pest management and the possibility of using mechanised harvesting methods for collecting aboveground plant parts.
