Here, the kinetics of oxidative stress responses of alfalfa (Medicago sativa) seedlings to cadmium (Cd) and mercury (Hg) (0, 3, 10 and 30 microm) exposure, expanding from a few minutes to 24 h, were studied. Intracellular oxidative stress was analysed using 2',7'-dichlorofluorescin diacetate and extracellular hydrogen peroxide (H(2)O(2)) production was studied with Amplex Red. Growth inhibition, concentrations of ascorbate, glutathione (GSH), homoglutathione (hGSH), Cd and Hg, ascorbate… Expand
