文摘	Study on the antioxidant systems of Polygonum viviparumgrown at two different altitudes indicated plants grown at Haibei Research Station at 3200 m altitude as compared with plants grown in Xining at 2300 m altitude had apparently higher contents of ultroviolet-absorbing compounds and ascorbic acid, and significantly higher activities of superoxide dismutase, peroxidase and ascorbic peroxidase. Higher contents of superoxide radical anions and malonadehyde were also found in plants at Haibei Research Station as compared with the plants grown in Xining which have been transplanted from Haibei Research Station for at least four years. The differences in antioxidant system reflect a long term of time of adaptation to different environments.
