Biomass Yield Stability of Switchgrass Cultivars
INTRODUCTION The development of viable bio-based energy systems offers many potential benefits relative to energy availability, national security, a cleaner environment, and associated economic rewards (DOE 2000). Largescale bioenergy use will require the deployment of environmentally acceptable energy crops and cropping systems for producing large quantities of low-cost, high-quality biomass f...
متن کاملBiomass Yield and Biofuel Quality of Switchgrass Harvested in Fall or Spring
Seasonal time of switchgrass (Panicum virgatum L.) harvest affects yield and biofuel quality and balancing these two components may vary depending on conversion system. A field study compared fall and spring harvest measuring biomass yield, element concentration, carbohydrate characterization, and total synthetic gas production as indicators of biofuel quality for direct combustion, ethanol pro...
متن کاملGenomic architecture of biomass heterosis in Arabidopsis.
Heterosis is most frequently manifested by the substantially increased vigorous growth of hybrids compared with their parents. Investigating genomic variations in natural populations is essential to understand the initial molecular mechanisms underlying heterosis in plants. Here, we characterized the genomic architecture associated with biomass heterosis in 200 Arabidopsis hybrids. The genome-w...
متن کاملHeterosis Decreasing in Hybrids--Yield Test Inbreds
U.S. corn production was 53 million Mg annually and corn yield averaged 1518 kg ha in the 1930s, when corn hybrids were first commercially grown. Corn production grew to 76 million Mg annually in the 1950s, to 150 million Mg annually in the 1970s, and to 219 million Mg in the 1990s (USDA/NASS 2007). In 2001 corn became the highest tonnage cereal crop worldwide: 557.6 million Mg of corn, 542.4 m...
متن کاملSwitchgrass and Big Bluestem Hay, Biomass, and Seed Yield Response to Fire and Glyphosate Treatment
just below the soil surface, such as crown buds or rhizomes, aids plant tolerance to fire. Timing of spring fire and glyphosate [N-(phosphonomethyl)glyFire may not be an option for managing warm-season cine] treatments is critical to control weeds without compromising grasses in densely populated areas of the northeastern production of warm-season grasses. To determine the forage and seed USA w...
