Development 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 کامل24 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 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 کاملAcclimation of photosynthesis to elevated CO2 under low-nitrogen nutrition is affected by the capacity for assimilate utilization. Perennial ryegrass under free-Air CO2 enrichment
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 tested by growing a perennial ryegrass (Lolium perenne) in the field under elevated (60 Pa) and current (36 Pa) partial pressures of CO2 (pCO2) at l...
