Increasing carbon dioxide relieves drought stress in corn, researchers say

when the research was conducted, was considered a typical one in terms of weather. However, at the end of a dry spell in June, Leakey found, carbon fixation increased under elevated carbon dioxide as much as 41 percent.

Since carbon dioxide serves to close the stomata, which are tiny pores in the epidermal layer of leaves, the jump in photosynthesis likely resulted from the plant maintaining higher water content in the leaves during the dry period, Long said.

The improvement in corn growth could be offset by the effects of rising ozone levels and other global warming factors, the researchers are quick to point out. While elevated ozone is part of the SoyFACE technology, corn has not yet been exposed to it. In soybeans, initial exposure to carbon dioxide led to increased yields that were later dramatically reversed by the effects of ozone.

The SoyFACE research area on the south end of campus features 70-foot octagon-shaped plots in which ABS plastic pipes deliver at crop level a precisely regulated flow of either carbon dioxide and/or ozone from 50-ton solar-powered tanks. Control rings surround equal amounts of control crops, which grow in normal conditions, without gases, for comparison purposes.

Construction began in 2000; research began the next spring. SoyFACE comprises more than 30 research groups with participants from 18 countries. Funding is provided by the Illinois Council for Food and Agricultural Research, the U.S. Department of Agriculture, the International Arid Lands Consortium of Astra-Zeneca, United Kingdom, the U.S. Department of Energy's Argonne National Laboratory, Archer Daniels Midland Co. and Pioneer Hi-Bred International Inc.
