The statistical analysis on fresh weight of stems and roots in M. sativa were obtained in the control, Phe/Cd and the combined Phe-Cd contaminated soil with or without P. indica colonization. Control with (Piri) or without (Con) P. indica inoculation; Phe contaminated soil with (Piri+Phe) or without (Phe) P. indica inoculation; Cd contaminated soil with (Piri+Cd) or without (Cd) P. indica inoculation; Phe-Cd co-contaminated soil with (Piri+Cd + Phe) or without (Cd + Phe) P. indica inoculation. M. sativa was planted in all treatments. Each value of fresh weight is the mean of three replicates. Error bars show standard error. The fresh weight in different treatments was significantly reduced or increased compared to the control according to the Duncan’s Multiple Range Test (P < 0.05)
