In the framework of a project aiming to phytoremediate contaminated soils with heavy metal Cr in Long Khanh city, Dongnai province, Southeast of Vietnam, a series of greenhouse experiments followed by field trials were performed in order to evaluate the effect of L. sphaericus on the Cr phytoextraction by S. nigrum. The results showed that L. sphaericus improved the Cr uptake efficiency of S. nigrum through changing growth parameters such as root length, height, biomass and the ability to accumulate Cr in plants. At an application rate corresponding to the T3 treatment in this experiment, L. sphaericus can stimulate the dry biomass of S. nigrum by 143%, increase the Cr concentrations in the aerial part by 70%, the content of Cr extracted in a single plant up to 293% compared to treatment without L. sphaericus.
