Effects of Cd [0 mg/kg (control) and 150 mg/kg CdNO3] on specific energy fluxes per reaction center (RC) for energy absorption (ABS/RC) (A) and trapped energy flux (TR0/RC) (B) of lettuce plants over 8 weeks after sowing and treatment with water, sulfate reducing bacteria (SRB), Spirulina (SP) and co-application of SRB and SP (SRB + SP). Each column represents the mean value of three replications ± standard error. Different letters indicate a significant difference between the means at the probability level of P < 0.05.
