24 FACE Value: Perspectives on the Future of Free-Air CO2 Enrichment Studies
Free-air CO2 enrichment (FACE) studies are the ultimate test bed for hypotheses that seek to explain how plants respond to rising [CO2]; and they provide the most realistic conditions for simulating the impact of future elevated (e)[CO2] levels (see Chapter 2). FACE studies have many benefits over controlled environment and open-top chamber (OTC) experiments. FACE allows the investigation of an...
متن کاملDevelopment of C4 photosynthesis in sorghum leaves grown under free-air CO2 enrichment (FACE).
The developmental pattern of C4 expression has been well characterized in maize and other C4 plants. However, few reports have explored the possibility that the development of this pathway may be sensitive to changes in atmospheric CO2 concentrations. Therefore, both the structural and biochemical development of leaf tissue in the fifth leaf of Sorghum bicolor plants grown at elevated CO2 have ...
متن کاملFree-air CO2 enrichment (FACE): blower effects on wheat canopy microclimate and plant development
Free-air carbon dioxide enrichment (FACE) provides a realistic, cost-effective method for evaluating the effects of supraambient CO2 concentrations on growth, development, yield, and water use of agricultural crops and natural ecosystems with very few of the problems normally associated with glasshouse or chamber type research. There are no walls interfering with incident radiation and no artif...
متن کاملBiotic, abiotic and performance aspects of the Nevada Desert Free-Air CO2 Enrichment (FACE) Facility
Arid and semiarid climates comprise roughly 40% of the earth's terrestrial surface. Deserts are predicted to be extremely responsive to global change because they are stressful environments where small absolute changes in water availability or use represent large proportional changes. Water and carbon dioxide ̄uxes are inherently coupled in plant growth. No documented global change has been mor...
متن کاملComparison of gas use efficiency and treatment uniformity in a forest ecosystem exposed to elevated [CO2] using pure and prediluted free-air CO2 enrichment technology
A direct comparison of treatment uniformity and CO2 use of pure and prediluted free-air CO2 enrichment (FACE) systems was conducted in a forest ecosystem. A vertical release pure CO2 fumigation system was superimposed on an existing prediluted CO2 fumigation system and operated on alternate days. The FACE system using prediluted CO2 fumigation technology exhibited less temporal and spatial vari...
