Abstract
Since a study of the intraspecific variation in the response to elevated CO2 of different genetic lines of one species might reveal the parameters essential for the response of a species to elevated CO2, thirteen lines of Arabidopsis thaliana L. were exposed to elevated CO2 (700 mul l(-1)). All lines increased shoot biomass, leaf area and starch content and most lines decreased specific leaf area (SLA) upon exposure to elevated CO2. The lines differed in the magnitude of their response to elevated CO2 (ratio 700/350), viz. 1.09 to 1.68 for the increase in shoot biomass, 1.00 to 1.44 for the increase in leaf area, 1.40 to 1.71 for the increase in starch content and 1.02 to 0.84 for the change in SLA. Both soluble sugar and structural dry matter content were hardly affected by elevated CO2. The changes in the various parameters are discussed in relation to the life strategy of Arabidopsis thaliana L.
