Reports Outline Greenhouse Gases Study Results from M. Baslam et al

June 20, 2014

By a News Reporter-Staff News Editor at Energy Weekly News -- Researchers detail new data in Greenhouse Gases. According to news reporting originating from Zaragoza, Spain, by VerticalNews correspondents, research stated, "Alfalfa is a widely distributed forage legume whose leaves are high in protein content and whose stems are suitable for bioethanol production. However, alfalfa forage digestibility, quality and yield may vary under future climate change scenarios."

Our news editors obtained a quote from the research, "This legume can establish double symbiosis with nitrogen-fixing bacteria and arbuscular mycorrhizal fungi (AMF). The presence of AMF can modify the evolution of biomass production and partitioning during the vegetative growth of alfalfa. We hypothesised that mycorrhizal symbiosis may change the quantity and/or quality of carbohydrates and lignin in leaves and/or stems of alfalfa, with these changes being dependent on the atmospheric CO2 concentration at which plants are grown. Results showed that mycorrhizal alfalfa plants exposed to elevated CO2 had improved leaf, stem and root biomass, enhanced amount of hemicellulose and decreased concentration of lignin in cell walls of leaves as well as increased levels of glucose and fructose in stems compared with non-mycorrhizal alfalfa. These results indicated improved forage quality (leaves) and enhanced potential for bioethanol conversion (stems) in mycorrhizal alfalfa cultivated under elevated CO2."

According to the news editors, the research concluded: "Moreover, the potential of stems for producing CH4 reinforced their suitability for the conversion of biomass into bioethanol."
