Abstract
The purpose of this study was to identify the effects of air pollution on the street trees in Seoul. Ten Gingko biloba street trees were selected in both Jongno(polluted area as a control) and Yangjae(non-polluted area) to investigate chlorophyll contents, photosynthesis and antioxidant enzymes such as APX(Ascorbate peroxidase) and GR(Glutathione reductase). The sampling, measurements and analysis were conducted in August. Chlorophyll contents and photosynthesis of Gingko biloba grown in Yangjae were higher than those of Jongno in the August measurement. In contrast, APX and GR activities of Gingko biloba grown in Yangjae were lower than those of Jongno. The observed tree responses are considered to be atypical compensatory response to polluted locations.
