Trifolium repens L. was grown to test the following hypotheses: when P is deficient (i) N 2 fixation decreases as a result of the plant's adaptation to the low N demand, regulated by an N feedback mechanism, and (ii) the decrease in the photosyntheti

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

Lolium perenne, a main component species in managed grassland, is well adapted to defoliation, fertilization, and regrowth cycles; and hence, to changes in the assimilatory carbon source-sink ratio. In the Swiss Free Air CO2 Enrichment experiment the

The effect of elevated (60 Pa) atmospheric carbon dioxide partial pressure (pCO2) and N fertilisation on the availability of mineral N and on N transformation in the soil of a Lolium perenne L. monoculture was investigated in the Swiss FACE (Free Air

The growth response of white clover (Trifolium repens L.) to the expected increase in atmospheric partial pressure of CO2 (pCO2) may depend on P availability. A decrease in the rate of transpiration due to increased pCO2 may reduce the amount of P tr

Acclimation of photosynthesis to elevated CO2 has previously been shown to be more pronounced when N supply is poor. Is this a direct effect of N or an indirect effect of N by limiting the development of sinks for photoassimilate? This question was t

Artificial chalk grassland swards were exposed to either ambient air or air enriched to 600 ?mol mol–1 CO2, using free-air CO2 enrichment technology, and subjected to an 8 week simulated grazing regime. After 14 months of treatment, ribulose-1,5-bi

The extent of the response of plant growth to atmospheric CO2 enrichment depends on the availability of resources other than CO2. An important growth-limiting resource under field conditions is nitrogen (N). N may, therefore, influence the CO2 respon
