Illinois-based study of energy crops finds miscanthus more productive than switchgrass

At the annual meeting of the American Society of Plant Biologists in Chicago (July 7-11, 2007), scientists will present findings on how to economically and efficiently produce plant crops suitable for sustainable bioenergy. Improving the production of such biomass is important because it should significantly ease and eventually replace dependence on petroleum-based fuels. Biomass is plant material, vegetation or agricultural waste used as fuel.

Converting biomass into biofuels can be costly and slow. Two crops, both classified as C4 perennial grasses, have been studied extensively to determine how best to improve costs and production rates. Switchgrass (Panicum virgatum) has been trialed across the United States. Miscanthus (Miscanthus x giganteus) has been studied throughout the European Union. Both show great promise, but until now, nobody has been sure which crop is more efficacious. The study completed by Frank Dohleman of the Plant Biology Department at University of Illinois at Urbana-Champaign and his colleagues, is the first to compare the productivity of the two grasses in side-by-side field trials. Results from trials throughout Illinois show that Miscanthus is more than twice as productive as switchgrass.

Dohlemans team, which included Dafu Wang, Andrew D.B. Leakey & Stephen P. Long also of University of Illinois, along with Emily A. Heaton of Ceres Inc., theorized that Miscanthus produces more usable biomass than switchgrass because of these three key attributes:

1. Miscanthus can gain greater amounts of photosynthetic carbon per unit of leaf area
2. Miscanthus has a greater leaf area
3. Miscanthus has a longer growing season.

The research team measured the amount of gas exchanged on the upper canopy of Miscanthus leaves from pre-dawn to post-dusk on 20 dates in the 2005 and 2006 growing seasons. The averages from two years data showed that Miscanthus gained 33% more carbon than switchgra
