Carbon Dioxide and Climatic Change Effects on Crops and Trace Gas Exchange with the AtmosphereEntry ID: USDA0518
Abstract: The purpose of the "Carbon Dioxide and Climatic Change Effects
on Crops and Trace Gas Exchange with the Atmosphere" dataset is
to determine the effect of elevated CO2 and temperature on
acclimation of photosynthesis, growth, and yield of rice, and on
emissions of methane. The data aid researchers in developing
strategies for management of soil water and cultivars for
decreasing methane emissions ... while maintaining high yields; and
to determine the effects of elevated CO2, high temperatures, and
soil water on growth and competition of bahiagrass and rhizoma
Collection Organization: USDA Agricultural Research Service
Collection Methodology: Rice grown in SPAR chambers under
setpoint CO2 concentrations, air temperatures, and soil water
conditions. Canopy photosynthesis and ET measured at 5 minute
intervals. Methane effluxes measured from the whole canopy,
individual plants, and paddy water. Paddy culture rice grown in
temperature gradient greenhouse (TGG) tunnels to evaluate
strategies for reducing methane emissions without decreasing
yields. Bahiagrass and rhizoma peanut grown in TGG tunnels to
evaluate responses to elevated CO2 and temperatures. Leaf
photosynthesis, stomal density, growth, development, rubisco and
other enzyme activities, nutrient content. and final yield
components measured in each study.
Collection Frequency: Ongoing research.
Update Characteristics: Ongoing.
Data Center: USDA Agricultural Research Service
Dissemination Media: Mainly in paper publications; data on local
Access Restrictions: There are no legal restrictions to access
but the dataset is not available online.
