Abstract
In this study, the generation of reactive oxygen species, the induction of oxidative stress, and the response of the antioxidative system in hydroponically grown tomato plants as the cause of arsenic-induced phytotoxicity are investigated. Reduction in plant growth was measured in terms of dry weight and length of roots and shoots, the latter accumulating more arsenic than the roots. The treatment resulted in increased formation of superoxide anion (O2.−), H2O2, and thiobarbituric acid reactive substances, which indicate augmented lipid peroxidation. Superoxide dismutase, catalase (CAT), and ascorbate peroxidase activities were increased in arsenic-treated tomato plants while CAT activity was insignificantly increased.
