| tThe response in production parameters to projected future levels of temperature, atmospheric carbondioxide ([CO2]), and ozone ([O3]) was investigated in 138 spring barley accessions. The comprehensive setof landraces, cultivars, and breeder-lines, were during their entire life cycle exposed to a two-factor treat-ment of combined elevated temperature (+5°C day/night) and [CO2] (700 ppm), as well as single-factortreatments of elevated temperature (+5°C day/night), [CO2] (700 ppm), and [O3] (100–150 ppb). Thecontrol treatment was equivalent to present average South Scandinavian climate (temperature: 19/12◦C(day/night), [CO2]: 385 ppm). Overall grain yield was found to decrease 29% in the two-factor treatmentwith concurrent elevation of [CO2] and temperature,... |
