Effect of Accumulator Plants on Growth and Nickel Accumulation of Soybean on Metal-contaminated Soil

Environmental damage caused by heavy metals will be difficult to recover naturally and require remediation efforts. The use of plants to absorb and remove contaminants from soil organic and inorganic forms and convert them into non-toxic forms known as Phytoremediation. A number of soybean are grown in pot along with the accumulator plants (Sarcotheca celebica and Melastoma malabathricum) were investigated their Ni accumulation. The results were indicates that planting soybean either with Melastoma or Sarcotheca could increase biomass production and Ni accumulation that higher than soybean alone. The highest biomass production and Ni accumulation were obtained by growing Melastoma with single soybean in pot.
