- Soil organic carbon and nitrogen accumulation in plots of rhizoma perennial peanut and bahiagrass grown in elevated carbon dioxide and temperatureLeon Hartwell Allen
USDA ARS, Crop Genetics and Environmental Research, University of Florida, Gainesville, FL 32611 0965, USA
J Environ Qual 35:1405-12. 2006..Eliminating elevated CO2 effects, overall mean SOC accumulation was 475 kg ha(-1) yr(-1). Conversion from cropland to forages was a greater factor in SOC accumulation than the CO2 fertilization effect...
- Leaf photosynthesis and carbohydrates of CO₂-enriched maize and grain sorghum exposed to a short period of soil water deficit during vegetative developmentVijaya Gopal Kakani
University of Florida, Agronomy Department, 304 Newell Hall, P O Box 110500, Gainesville, FL 32611 0500, USA
J Plant Physiol 168:2169-76. 2011..Such a response in ADGP to drought, however, did not occur for sorghum. The generally more rapid response of maize than sorghum to drought might be related to the more rapid growth of leaf area of maize...
- Elevated CO2 increases water use efficiency by sustaining photosynthesis of water-limited maize and sorghumLeon Hartwell Allen
United States Department of Agriculture Agricultural Research Service, Center for Medical, Agricultural and Veterinary Entomology, Chemistry Research Unit, 1600 1700 SW 23rd Drive, Gainesville, FL 32608 1069, USA
J Plant Physiol 168:1909-18. 2011..Furthermore, less water might be required for C(4) crops in future higher CO(2) atmospheres, assuming weather and climate similar to present conditions...
