Effect of chromium accumulation on photosynthetic pigments, oxidative stress defense system, nitrate reduction, proline level and eugenol content of Ocimum tenuiflorum L

Ocimum tenuiflorum L. exposed to various concentrations of chromium (0.0, 10.0, 20.0, 50.0, 100.0 μM) accumulated high amount of chromium in various plant parts in a concentration and duration dependent manner. Chromium induced lipid peroxidation coupled with potassium leakage. Toxic effects of chro...
