| Abstract/Contents: | "Biomass of genotypes of Carex flacca and Bromus erectus under CO2 enrichment was measured to test for `winners' and `losers' within the populations. Allocation was studied to identify reasons for varying biomass responses of the genotypes. In a first experiment, genotypes of both species were grown separately and mown five times. In a second experiment, introducing species interaction, species were grown together (using nine genotypes of each) and harvested destructively during that time. The first experiment showed that growth stimulation across harvests (Bromus +15%; Carex +11%) and genotype x CO2 treatment interactions in single harvests was significant, but repeated measures ANOVA was not (Carex) or only marginally significant (Bromus). Destructive harvests in the competition experiment indicated a significant growth stimulation (Bromus +28%, Carex +35%), but no CO2 x genotype interaction was found. Similarly, ANOVA of dry matter allocation never indicated a significant CO2 x genotype interaction. The lack of a sustained CO2 x genotype interaction in isolated and competitive growth conditions with good moisture supply suggests, that if there is such an interaction, it must be very small." |
