B contamination in wastewater is a serious human and environmental health concern. Remediation is difficult and phytoremediation is a promising approach.
Seven hybrid poplar clones were selected to remove B through phytoextraction.
High B aqueous concentrations lead to high B accumulation in plant tissue and negatively impacted plant biomass.
Clone 195–529 had the highest B accumulation and tolerance.
Varying salinity levels range from beneficial to harmful for poplar growth and B removal.
