Even though there was preferential accumulation in roots and rhizomes, several field studies observed P. australis could also be used as a phytoextractor. In fact, despite low copper concentrations in aboveground structures per g of tissue, this plant can accumulate significant amounts of the metal in these structures, considering its abundant aerial biomass. As seen in this work, aerial biomass accounted for more than 80% of total plant weight. Despite the biomass decrease observed in stems when microbial consortium was added, plant phytoextractor potential was verified, because total copper in stems was higher when microbial consortium was added.
