Control of yellow and purple nutsedge in elevated CO2 environments with glyphosate and halosulfuron.
TL;DR: It is likely that predicted future CO2 levels will have little impact on the efficacy of single applications of halosulfuron or glyphosate for control of purple and yellow nutsedge at the growth stages described here, although scenarios demanding more persistent control efforts remain a question.
Journal ArticleDOI
Elevated CO2 and plant structure: a review
TL;DR: A review of the literature suggests that cell division, cell expansion, and cell patterning may be affected, driven mainly by increased substrate (sucrose) availability and perhaps also by differential expression of genes involved in cell cycling or cell expansion.
Journal ArticleDOI
Root to shoot ratio of crops as influenced by CO2
TL;DR: In this article, the root to shoot ratio (R:S) is defined as the dry weight of root biomass divided by dry body weight of shoot biomass, which is a measure of the proportion between root and shoot.
Journal ArticleDOI
An evaluation of cassava, sweet potato and field corn as potential carbohydrate sources for bioethanol production in Alabama and Maryland
Lewis H. Ziska,G. Brett Runion,Martha B. Tomecek,Stephen A. Prior,H. Allen Torbet,Richard C. Sicher +5 more
TL;DR: In this paper, the potential of alternative crops as sources of bioethanol production was assessed by growing sweet potato and cassava at locations near Auburn, Alabama and Beltsville, Maryland in order to measure root carbohydrate (starch, sucrose, glucose) and root biomass.
Journal ArticleDOI
Effects of Elevated Carbon Dioxide and Increased Temperature on Methane and Nitrous Oxide Fluxes: Evidence from Field Experiments
Feike A. Dijkstra,Stephen A. Prior,G. Brett Runion,H. Allen Torbert,Hanqin Tian,Chaoqun Lu,Rodney T. Venterea +6 more
TL;DR: In this paper, the authors assessed how N2O and CH4 soil fluxes responded to a rise in atmospheric carbon dioxide (CO2) concentration and to increased air temperature.
