Abstract

The purpose of this study is to investigate Ozone which we have to contact in our daily lives. Recently Ozone becomes a serious pollutant in the inside and outside. To select th indicator plants or the purifier plants for air pollution caused by ozone, this stud has been conducted with interior landscape plant of 10 species. The results are as follows; 1) The visible demage by Ozone was firstly observed on Viburnum awabuki among 10 species, and it occurred after the lapse of 10, 8 and 4 hours on 0.5, 1.0 and 2.0 ppm ozone treatment, respectively. The first symptom of visible demage appeared on chlorosis or blotting of leaves, then progressed on necrosis of leaves. 2) On the other hand, Litsea japonica and Ardisia japonica were so resistant against Ozone fumigation that they were not demage independently of Ozone concentration till the lapse of 60 hours. 3) Chlorophyll contents were decreased by the increased Ozone concentration. At this time, grana destruction was observed. The most sensitive plant to ozone was Viburnum awabuki, and we suggest that Viburnum awabuki would be possible one to use for the indicator plant. The most resistance plant to Ozone was Litsea japonic and Ardisia japonica, we suggest that Litsea japonica and Ardisia japonica would be possible to use for the purifier plant for Ozone pollution.
