Abstract

We investigated the effect of O3 on the photosynthetic characteristics of tree of heaven (Ailanthusaltissima) that is naturalized plant and used as restoration plant for contaminated area. Two-year-old seedlings were planted to pots and transferred into closed O3synthetic characteristics were measured every three weeks under 100 ppb O3 fumigation. There was no visible foliar injury by O3 exposure and contents of photosynthetic pigments did not show significant differences between control and O3-treated seedlings. Also there were no significant differences in stomatal conductance, and water use efficiency. But photosynthetic rate and apparent quantum yield (AQY) of O3 treated seedlings were reduced after nine weks of ozone fumigation. In addition, the reduction of carboxylation efficiency and photorespiration were observed in the leave of O3 system of A. altissima was most sensitive to O3 stress to evaluate physiological damage induced by O 3.
