Description
Perennial ryegrass swards were grown during two years at two N fertilizer supplies in elevated (700 ppm) or ambient atmospheric CO2 concentration at outdoor temperature and at + 3°C in elevated CO2. Elevated CO2 and temperature increase had only minor impacts on the digestibility and on the fiber composition of the cut material. On average, the water soluble carbohydrate concentration of the leaf laminae was doubled in elevated CO2, whereas a 3°C temperature increase reduced this concentration by 25 %.
