Establishing Native Grasses Along Maryland Roadways
The use of native grasses and other meadow species in roadside rights-of-way is perceived as environmentally and economically beneficial. There is a need for more information about successful establishment procedures appropriate for the mid-Atlantic region. This study examined the use of companion …

Control of two perennial grasses in southern turfgrasses
… torpedograss (Panicum repens L.) are perennial grasses that are extremely difficult to remove in established turfgrass. Studies were conducted to determine the potential for controlling these troublesome perennial weeds. Pot studies were conducted for two years to evaluate several herbicides …

Decomposition of grasses in a South African savanna
Tropical and subtropical grasslands ecologists have ignored decomposition, because of the important role it plays in nutrient cycling, in terms of understanding how grass litter gets to the soil during the dry season. The major flaw is in the methods employed to investigate decomposition. In the …

Evolutionary history of the canary grasses (Phalaris, Poaceae)
Canary grasses (Phalaris, Poaceae) include 21 species widely distributed throughout temperate and subtropical regions of the world with centers of diversity in the Mediterranean Basin and western North America. The genus contains annual/perennial, endemic/cosmopolitan, wild, and invasive species …

Perennial grasses as sustainable bioenergy crops for marginal lands
… was no significant difference found among the grasses for cellulose and hemicellulose concentration in tissue. Waterlogging in poorly drained soils can cause flooding that can delay early-season planting and also, cause difficulties in field operation in late season. High salinity is also a …

The Suitability of Native Warm-Season Grasses for Equine
Introduced cool-season grasses are dominant in Virginia's grasslands, but their high digestible energy and non-structural carbohydrate (NSC) levels pose a risk for horses prone to obesity and laminitis. Native warm-season grasses (NWSG) have lower digestible energy and NSC levels that may be more …

Palatability and digestibility of grasses treated with gibberellic acid
… acid on palatability and digestibility of two grasses, orchard grass and Kentucky 31 fescue. The GA was applied as a spray, except one granular application, at rates of 18 to 72 gm./A. Sheep were used to test the grass for palatability and digestibility. In addition to proximate analysis of …

A tale of two grasses: Seed production has small & potentially positive effects on seed & seedling traits of squirreltail grasses, but Thurber’s needlegrass resists farming
… establishment. Focusing on two native perennial grasses in the western United States, including three populations of Elymus sp., or squirreltail, and three populations of Achnatherum thurberianum, Thurber’s needle grass, we asked how one generation of farming affected plant traits. We focused on …

Photosynthetic adaptations in grasses to abnormal levels of soil cations
… of photosynthesis manifest in populations of grasses adapted to growth on abnormal levels of cations. The main investigative plants belong to the Agrostis genus. Plants were sampled from habitats with soi.ls which provided a range of abnormal levels of cations; mine spoil sites with heavy …

Nutritional Value of Warm- and Cool-Season Grasses for Ruminants
… (Dactylis glomerata L.). The warm-season grasses (bermudagrass and bluestem) were higher (P < .01) in fiber components than the cool-season grasses (tall fescue and orchardgrass). Bluestem was lower (P < .001) in CP, hemicellulose, and ash, and higher in NDF (P < .001), ADF (P < .001), …

Senescence of Native Perennial Warm Season Grasses Senescence Associated Switchgrass Transcriptome
<p>Senescence of perennial crops enable continuous harvests after one sowing event. Perennials senesce at adapted rates of their native environments; however, early senescencing crops do not maximize the growing season as nutrient reallocation takes precedence. Chlorophyll degradation and nitrogen …
