Abstract excerpt
The impact of sequential exposure to ozone (O3) and UVB (290-320 nm) was studied using two genotypes of Arabidopsis thaliana differing in UVB sensitivity. The negative impact of UVB on dry matter production and photosynthetic pigments was absent in the ecotype Landsberg erecta (LER), while the negative impact of UVB was more pronounced when LER plants pre-exposed to O3 were irradiated with UVB. However, the...
