英文摘要	Four-year-old seedlings of Ginkgo biloba were exposed to elevated O-3, elevated CO2 and elevated O-3 plus elevated CO2 in open-top chambers (OTCs) to study the responses of antioxidant system in Ginkgo biloba leaves. No significant changes in reactive oxygen production and scavenging systems were detected in seedlings exposed to high CO2. Significant increase in H2O2 and MDA content were induced by elevated O-3. The ascorbate content and antioxidative enzymes activity were increased significantly by exposure to high O-3 as well. But the promoted ability in scavenging did not prevent the increase in H2O2 content and cell membrane lipid peroxidation. The increase was mitigated by high CO2 in the combined exposure, but the effect was hardly significant.
