|| effect of long term exposure to elevated CO2 levels on biomass production at 18 herbaceous plant species was studied. The grain yield, CO2 gas exchange, and water uptake on plant communities of Trifolium pratense and festucs prstensis were examined at 340 represent ambient conditions, 450, 600 and 800 ppm atmospheric CO2 concentrations in mini - glasshouses under field conditions. Plant species grown at nearly doubling CO2 differed widely in the response to dry weight accumulation, all species together show an average increase of about 30|
dry weight. (AU)
