Superoxide dismutase (SOD) activities were investigated from the portions of shoots
and roots in accordance with developmental stage and in response to environmental stress and
antioxidants using Rhodiola-seedlings.
The rates of SOD activities were revealed highly at the portion of roots and its tip of seedlings in
the latter stages rather than the initial stages. SOD activities of seedlings in the initial stages treated
with sodium chloride and cadmium as environmental stressors showed the decrease by 15 and
30% with respect to the control, respectively. However, in spite of stressor-treatments, the activities
in the roots were increased according to the growth period showing a maximum rate of up to
45%. Also, SOD activities of the seedling treated with ascorbic acid as a antioxidant were increased
by 46% of control value, but this was similar to the rate revealed in the presence of stressors.
These results suggest that SOD activities in Rhodiola-seedlings may be related with the important
defence-system against injurious environments.
