The effects of elevated ozone (O-3) on yield, growth, photosynthetic rate, whole-plant C-14- allocation and biomass of two strawberry (Fragaria x ananassa Duch.) cultivars were investigated. The two cultivars (Bogota and Elsanta) were at the beginning and end of fruiting, respectively, when exposed to 74 ppb ozone (O-3) (8-h day(-1)) for 7 and 11 weeks, respectively, in open-top chambers. O-3 reduced yield without affecting growth and biomass in cv. Bogota. The photosynthetic rate was lower in O-3 in cv. Bogota and there was a trend that increased C-14-allocated after 24-h to developing leaves in O-3. In post-fruiting Elsanta, O-3 did not significantly affect the photosynthetic rate, growth and above-ground biomass. However, root biomass was significantly lower in O-3; O-3 also caused an increase in 1(4C)-allocated after 27 days to the old leaves.
