"To test whether different nitrogen form (nitrate or ammonium) in substrate can alter the response to elevated partial pressure Of CO2 (PCO2) plants of perennial ryegrass (Lolium perenne cv. Bastion) were grown from seeds in growth chambers under PCO2 of either 35 Pa (ambient, CA) or 70 Pa (elevated, CE) in a hydroponic system (with nutrient and pH control) for 24 d. Nitrogen was supplied as ammonium, nitrate or an equimolar mixture of both N forms. Under CE plants grew faster than their counterparts under CA during the first 14 d but after 23 d of cultivation stimulation disappeared. Despite the strong positive effect of mixed forms of N on plant growth, the beneficial effect of CE was similar to that in the other,two N treatments. However, the almost alike final growth response to CE had different underlying mechanisms in different N treatments.
