Ozone is not mutagenic in the Tradescantia and tobacco mutagenicity assays.
Ozone fumigation of a double heterozygous chlorophyll mutant Nicotiana tabacum var. xanthi n.c. with concentrations up to 300 nl/l and of a heterozygous Tradescantia clone 4430 with concentrations up to 800 nl/l did not increase the frequency of somatic mutations above the spontaneous levels. However, ozone fumigation at these concentrations led to distinct physiological damage to plant tissues.
