Boosts in productivity of corn and other crops modify Northern Hemisphere carbon dioxide cycle（图）
productivity of corn Northern Hemisphere carbon dioxide cycle
2014/12/1
Each year in the Northern Hemisphere, levels of atmospheric carbon dioxide drop in the summer as plants "inhale," then climb again as they exhale after the growing season.
Spatial variation of carbon dioxide fluxes in corn and soybean fields
Spatial Variation Transects Soil Organic Matter
2013/3/4
Spatial variation of soil carbon dioxide (CO2) flux during a growing season within corn and soybean canopies has not been quantified. These cropping systems are the most intense in the United States a...
Effects of carbon and nitrogen sources and ratio on the germination, growth and sporulation characteristics of Metarhizium anisopliae and Beauveria bassiana isolates
Metarhizium anisopliae nutrition germination growth sporulation Beauveria bassiana
2010/9/13
The entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana are ubiquitous and widespread with well documented broad-spectrum myco-pesticidal effects. It has been reported that nutrient s...
Rhizodeposition of Mucilage, Root Border Cells,Carbon and Water under Combined Soil Physical Stresses in Zea mays L.
Crushed cells Deuterium Drought Maize Rhizodeposition Root exudation Soil compaction
2010/3/4
We investigated the effects of combined soil physical stresses of compaction and drought on the production of fully hydrated mucilage (mucilage) and root border cells (RBCs) in maize. The exudation of...

Current assimilate Diurnal change Respiration Respiratory substrate Rice Oryza sativa L.
2009/8/6
The time course change of the shoot respiration rate, the percentage of currently assimilated carbon in respiration and the amounts of current and reserved compounds in the shoots of rice plants were ...
Studies on the Response of Nodulated Soybean to Nitrogen Fertilizer:I. On the carbon dioxide exchange of shoots and undergroud organs
Biomass production CO2 exchange Glycine max Nitrogen fertilizer Seed yield
2009/8/5
The effect of nitrogen fertilizer on biomass production, nodulation, seed yield and CO2 exchange was determined in soybean (Glycine max Merr. cv. Akiyoshi) grown in a pot sand culture in a glasshouse....
The Regulation of Maize Mesocotyl Growth by Ethylene and Carbon Dioxide
Carbon dioxide Darkness Ethylene Maize Mesocotyl Red light
2009/7/29
Ethylene stimulated the elongation of maize mesocotyls of whole seedings under red light. Maximum elongation was obtained with 1μl1-1 ethylene. The length of mesocotyls was still much longer than in e...
Effects of Atmospheric Partial Pressure of Carbon Dioxide and Phosphorus Nutrition on the Ultrastructure of Rice (Oryza sativa L.) Chloroplasts
Carbon dioxide Chloroplast Mesophyll cell Rice Phosphorus Starch accumulation
2009/7/29
Rice plants were grown in artificially illuminated growth cabinets under combinations of atmospheric partial pressure of CO2 (35 vs. 70 Pa) and phosphorus (P) nutrition (3 vs. 300 μM) to examine their...
Carbon and Nitrogen Dynamics with Aging in Seminal Root System of Rice Seedling
Aging Carbon Lateral roots Nitrogen Partitioning
2009/7/29
The allocation pattern of carbon (C) and nitrogen (N) with aging among several organs of rice seedling was investigated with particular attention to the difference in seminal root axis (SRA) and conco...
Changes in Photosynthetic Activity and Export of Carbon by Overexpressing a Maize Sucrose-Phosphate Synthase Gene under Elevated CO2 in Transgenic Rice
Elevated CO2 Export of carbon Rice Sucrose-phosphate synthase Transgenic plant
2009/7/29
To investigate whether increased sucrose-phosphate synthase (SPS) activity alters photosynthetic activity and/or the export of carbon from leaves under elevated CO2 partial pressure ([CO2]), we raised...
