The Genomic Basis of Heterosis in High-Yielding Triploid Hybrids of Willow (Salix spp.) Bioenergy Crops
… renewable energy production from lignocellulosic bioenergy crops such as shrub willow (Salix spp.), can help offset fossil fuel usage without competing with food crops. Hybridization is a key component in shrub willow breeding because hybrids often exhibit heterosis for yield. The genomic basis of …

A comparison of canopy evapotranspiration for maize and two perennial grasses identified as potential bioenergy crops
… The potential widespread use of biomass crops for renewable energy production has sparked numerous environmental concerns, including the impacts of land-use change on the hydrologic cycle. We predicted that total seasonal evapotranspiration (ET) would be higher for PRGs relative to maize …

Carbon Dioxide Emissions from Switchgrass and Cottonwood Grown as Bioenergy Crops in the Lower Mississippi Alluvial Valley
… potential to be utilized for the production of bioenergy feedstocks. Soil respiration is the gaseous emission of carbon dioxide (CO<sub>2</sub>) from microbes and plant roots in the soil, and these emissions play an important role in the global cycling of carbon. Soil respiration can act as a …

Expansion of bioenergy crops in the midwestern United States: implications for the hydrologic cycle under climate change
To meet emerging bioenergy demands, significant areas of the large-scale agricultural landscape of the Midwestern United States could be converted to 2nd generation bioenergy crops such as miscanthus and switchgrass. Their high biomass productivity in a longer growing season linked tightly to water …
