- Abstract:
- The objective of this experiment is to reveal the toxicological mechanism under elevated ozone concentration and UVB radiation singly or in combination on plant antioxidation enzymes activities and POD isoenzyme.Opentop chambers(OTCs)were utilized to investigate change of antioxidation enzymes activities and POD isoenzyme band in soybean(Glycine max)leaves under elevated ozone concentration and UV-B radiation singly or in combination treatment.The results of anti-oxidation enzymes activities indicated that either O3 treatment or UV-B treatment induced a decrease on SOD，POD and CAT，and in the combined stress，antioxidation enzymes activities had intensified this trend to a certain degree.The result of POD isozyme band showed that a new band appeared under O3 treatment in branching stage and two new bands appeared in flowering stage and podding stage compared of branching stage，and the shade of color of POD isoenzyme bands was lighter compared to CK treatment.It was suggested that in all growth period，POD isoenzyme activity was inhibited under combined stress.
