| Summary: | This paper present the influence of ascorbic acid and citric acid upon the mitotic division, and to the activity
of some antioxidant enzymes to Picea abies (L.) Karst. The treatment was made through the germination of seeds in
ascorbic acid and citric acid. We observed the stimulator or inhibitor effect of ascorbic acid and citric acid to the mitotic
index and estimated the aberrations appearance. Comparative the control, the mitotic index increased at 0.1 %
concentration ascorbic acid and decreased at 0.25 % and 0.5 % concentration of the same substance. The citric acid
induced a decrease in the dynamics of mitotic index comparative the control. Also, we observed an increase of
aberrations appearance to the treatment with citric acid. We established the activity of catalase, peroxidase and
superoxide dismutase and the influence of ascorbic acid and citric acid to the activity of these antioxidant enzymes. After
statistical interpretation emerged that these substances (except 0.25 % ascorbic acid) induced an inhibition of catalase
activity and a stimulation of peroxidase and superoxide dismutase activity. |
