In the present study, toxic effects of BPA and TBBPA on chickpea seed germination and some possible biochemical changes in the roots were determined. The seed germination did not significantly change in 10 and 50 mg/L BPA and TBBPA applications. However, seed germination was inhibited by 100 mg/L concentration of both treatments. Similarly, chickpea root development was adversely affected by high concentrations of BPA and TBBPA. Applications of BPA and TBBPA-induced oxidative stress in the roots demonstrating by H O formation as well as correlated quantitatively with malondialdehyde (MDA), peroxidase 2 2 (POD) activity and non-protein SH groups. Toxic effects of BPA and TBBPA on the roots were histochemically determined as well. In terms of stainings, degree of lipid peroxidation rose violently with the concentrations applied, especially in TBBPA. Staining with evans blue stated that the integrity of the plasma membrane of roots was relatively protected in low concentrations of BPA and TBBPA. However, the integrity was not maintained at high concentrations of both chemicals, especially TBBPA. Chickpea has the capacity to tolerate the oxidative stress at 10 and 50 mg/L concentrations of both treatments, but the capacity partly lost at 100 mg/L concentrations of BPA and TBBPA as revealed by POD activity and non-protein SH groups
