This study is conducted to identify responses of plants to low $O_3$ concentration, Five species, Liriodendron tulipifera, Cornus officinalis, Ginkgoba biloba, Zelkova serrata, and Acer palmatum, were exposed to low ozone concentration from June 9 to July 8 in the phytotron, We measured chlorophyll contents, leaf diffusion resistance, leaf transpiration, and antioxidant enzyme activities; ascorbate peroxidase(APX), Especially, Liriodendron tulipifera and Cornus officinalis showed sensitive responses to ozone treatment as visible injuries, while other four species relatively showed tolerant responses. However, we noticed that almost all species under ozone treatment were lower physiological activities such as chlorophyll contents, leaf diffusion resistance, leaf transpiration, and antioxidant enzyme activities with time even without any visible injury.
