Global Climate Change and Agricultural ProductivityEntry ID: USDA0287
Abstract: The purpose of the "Global Climate Change and Agricultural
Productivity" dataset is to investigate the interaction of
elevated atmospheric ozone and carbon dioxide on plant
physiology, growth, and yield. It contains data on climate and
its effects on plants. Physiological response mechanisms and
biochemical mechanism of stress resistance investigated by
cooperative research with German scientists ... working on similar
Collection Organization: USDA Agricultural Research Service.
Collection Methodology: Test plants treated with controlled
concentrations of ozone and carbon dioxide using field,
greenhouse, and controlled-environment chambers. Effects on
growth and productivity determined by periodic harvest of plant
material from early growth stages through physiological
maturity. Photosynthesis measured in situ on a weekly schedule
as an indicator of productivity using gas exchange techniques.
Mechanisms of response determined by diagnostic gas exchange
measurements and analysis of Rubisco quantity and activation
state. Similar experiments done by scientists at Braunschweig
and Giessen, Germany but with different plant species.
Collection Frequency: Varies widely depending on data type.
Update Characteristics: Update yearly or until project
5 megabytes each year.
