Abstract
The joint effect on the growth of wheat seedlings under Cd2+ stress (0, 0.5 mmol L−1) and [C2mim][OAc] with a series of concentrations (0, 100, 200, 300, 400, 500 mg L−1) was investigated. Physiological characteristics including superoxide dismutases, peroxidases, catalase and malondialdehyde were studied in hydroponic and soil cultures. Results indicated that, compared to samples treated under Cd2+ stress alone, joint treatment groups showed Cd2+ stress was mitigated by ionic liquid at appropriate concentrations (≤400 mg L−1 in hydroponic treatments and ≤300 mg L−1 in soil culture treatments). Use of inductively coupled plasma mass spectroscopy showed less Cd2+ in organelles in the joint treatment group. This phenomenon could be due to [C2mim][OAc] forming metal complexes with Cd2+, thus reducing the amount of free Cd2+ available for absorption by the seedlings.
