Abstract: | Bio-effects of static magnetic fields on cell growth and cell death have been investigated in suspension-cultured tobacco
cells as undifferentiated, embryonic plant cell model. The cells in their logarithmic growth phase were exposed to static
magnetic field with the magnitudes of 10 mT and 30 mT for 5 h/day. Exposure to static magnetic field ceased the growth and
caused an increase in cell death of exposed tobacco cells compared to those cells which were not treated with the field. Promotion
of cell death was accompanied by a harmonized increase in the activity of peroxidase and increase of lignifcation of cell
walls. |
