To study the efficiency of cadmium resistant bacteria on the promoting of cadmium phytoremediation by G max L., seedlings of G max L. were individually transplanted in 25-cm-diameter of plastic pots containing 3 kg of cadmium contaminated soil. This experiment was designed into 8 treatments with 3 replicates which were designed by completely randomized design (CRD). The detail of each treatment presents in Table 3-2.
