abstract = {The productivity of many important crops is significantly
threatened by water shortage, and the elevated atmospheric
CO2 can significantly interact with physiological processes
and crop responses to drought. We examined the effects of
three different CO2 concentrations (historical ~300 ppm,
ambient ~400 ppm and elevated ~700 ppm) on physiological
traits of oilseed rape (Brassica napus L.) seedlings
subjected to well-watered and reduced water availability.
Our data show (1) that, as expected, increasing CO2 level
positively modulates leaf photosynthetic traits, leaf
water-use efficiency and growth under non-stressed
conditions, although a pronounced acclimation of
photosynthesis to elevated CO2 occurred; (2) that the
predicted elevated CO2 concentration does not reduce total
evapotranspiration under drought when compared with present
(400 ppm) and historical (300 ppm) concentrations
because of a larger leaf area that does not buffer
transpiration; and (3) that accordingly, the physiological
traits analysed decreased similarly under stress for all CO2
concentrations. Our data support the hypothesis that
increasing CO2 concentrations may not significantly
counteract the negative effect of increasing drought
intensity on Brassica napus performance.},
