The current study was conducted using basil plants (Ocimum basilicum) combined with mycorrhizal inoculation to remediate a Ni-polluted soil. Basil plants were cultivated for 90 days under different levels of artificially Ni-pollution 0, 200, 400, 600, 800 and 1000 mg Ni kg-1 soil. Mycorrhiza increased fresh weight by18.27 and 47.80% and dry weight by14.79 and 46.32% for shoots and roots, respectively. Mycorrhiza increased basil potentials in extracting and immobilizing Ni and its uptake by plants increased by 53.43% and 187.59% for shoot and root respectively in presence of mycorrhiza. Mycorrhiza decreased the value of translocation factor (TF). A marked decrease in mycorrhizal infection occurred due to exposure to high level of Ni-pollution. |
