Project Number: 8042-11210-008-00
Start Date: Apr 04, 2010
End Date: Apr 03, 2015
Research will focus on determining how rising temperature alters responses of crop and weed physiology, growth, and product quality to elevated carbon dioxide. Differences among genotypes within several crop species in responses to elevated carbon dioxide and temperature will be assessed to identify traits which would help to adapt crops to these global change conditions. Responses of weeds in a locally and nationally important crop system will be evaluated to determine if rising atmospheric carbon dioxide and temperature will increase their impact on crop yields and their resistance to control by glyphosate, a popular herbicide. Work will be conducted in controlled environment chambers and in field plots with open top chambers and with a free air carbon dioxide enrichment system.
