Tóm tắt

AbstractEffects of magnetic fields (MFs) on the activities of antioxidant enzymes of suspension‐cultured tobacco cells were investigated. Compared with the control cells, exposure of the cells to static MF with the magnitudes of 10 and 30 mT for 5 days, 5 h each day, increased the activity of superoxide dismutase (SOD). In contrast, the activity of the catalase (CAT) and ascorbate peroxidase (APX) was decreased by MF, compared with those of the control cells. Level of lipid peroxidation was also increased by MF. It suggests that MF could deteriorate antioxidant defense system of plant cells. Bioelectromagnetics. © 2006 Wiley‐Liss, Inc.
