In this paper, we will present results of plasma treatments of
meristematic cells of Daucus carota. Plasma needle was used as an
atmospheric pressure/gas composition source of non-equilibrium plasma in
all treatments. Activity of antioxidant enzymes superoxide dismutase and
catalase was measured immediately after plasma treatment and after two
weeks following the treatment. Superoxide dismutase activity was
increased in samples immediately after the plasma treatment. On the
other hand, catalase activity was much higher in treated samples when
measured two weeks after plasma treatment. These results show that there
is a direct proof of the triggering of signal transduction in the cells
by two reactive oxygen species H2O2 and O-2(-), causing enzyme activity
and short and long term effects even during the growth of calli, where
the information is passed to newborn cells over the period of two weeks.
