Effect of Ni content in different fertility soils on the growth and biomass of plantain was conduced. The results showed that plantain has some extent tolerance to Ni

when Ni content in soils was reached 150 mg/kg the growth of Plantain was not significantly influenced by heavy metal toxicity. There was positive relationship between biomass and N contents (P<0.01). Ni content in plantain root increased as the levels of soil Ni contents (P<0.01)

while shoot dry weight decreased (P<0.01). There is a higher accumulation rate of Ni by plantain from soil (6.17%)

especially in the poor fertility soil. Therefore

plantain is a good phytoremediation plant in medium contamination soils by Ni.
