This study investigated the removal effectiveness of Escherichia coli by five pilot bioretention units with different vegetations. The bioretention units were originally planted or seeded with one of the following vegetation: shrubs, grass species specified for Texas highway applications, Texas native grasses, Bermudagrass (Cynodon dactylon), and none (control unit). To mimic highway conditions...

It is well-documented that endophytes can enhance the resistance of agronomical grasses, such as tall fescue and perennial ryegrass to herbivory. For native grasses, however, the related reports are limited, and the conclusions are variable. Achnatherum sibiricum is a grass native to the Inner Mongolian steppe. This grass is highly infected by endophytes but does not produce detectable endophyt...

Journal of Plant Registrations, Vol. 3, No. 1, January 2009 99 Switchgrass (Panicum virgatum L.) is a warm-season, perennial bunchgrass that is native to North America. Historically, it has been used as a forage and conservation grass, but more recently, the grass has received considerable attention as a bioenergy crop for the production of cellulosic ethanol (Vogel, 2004). Because of its poten...

The prairie grass (Bromus catharticus Vahl) is the annual/biennial native forage of temperate climates most importance and diffusion in Argentina. Several authors have studied phenotypic variability morphophysiological characters cultivars populations grass. first commercial were heterogeneous that considered best adapted region Genetic, agronomic molecular characterization selection base germp...

Rhizoremediation involves the breakdown of contaminants in soil resulting from microbial activity that is enhanced in the plant root zone. The objective of this study was to assess Australian native grasses for their ability to stimulate removal of aliphatic hydrocarbons from a mine site soil. Time-course pot experiments were conducted in a greenhouse with three grass species (Cymbopogon ambigu...

BACKGROUND Allergoids are chemically modified allergen extracts administered to reduce allergenicity and to maintain immunogenicity. Oralair® (the 5-grass tablet) is a sublingual native grass allergen tablet for pre- and co-seasonal treatment. Based on a literature review, meta-analysis, and cost-effectiveness analysis the relative effects and costs of the 5-grass tablet versus a mix of subcuta...

Introduced perennial grasses are one of the greatest constraints to prairie restoration. Herbicides suppress but do not eliminate introduced grasses, so we explored the interaction of herbicide with two additional controls: heavy clipping (to simulate grazing) and competition from native species. A 50-year-old stand of the introduced perennial grass Agropyron cristatum (crested wheatgrass) in t...

flare reactions at the injection site to severe life-threatening anaphylactic reactions. Consequently, a multitude of strategies on how to interfere with the unintended allergenic activity of whole allergens has been developed in the past. These strategies include, but are not restricted to, the application of variant forms of major allergens such as chemically modified allergens, allergen frag...
