1. Biological invasion can permanently alter ecosystem structure and function. Invasive species are difficult to eradicate, so methods for constraining invasions would be ecologically valuable. We examined the potential of ecological restoration to constrain invasion of an old field by Agropyron cristatum , an introduced C 3 grass. 2. A field experiment was conducted in the northern Great Plain...

Tall fescue (Schedonorus phoenix (Scop.) Holub) is a cool season perennial grass that fills a critical forage produc-tion gap in the Southeast and is the predominant forage crop in much of the U.S. In fact, this species is the most widely used grass in improved U.S. pastures, occupying more than 36 million acres. Its popularity is related to establishment ease, drought tolerance, excellent graz...

environmental stresses, such as salinity can play an important role in disturbing different stages of plant growth, development, and especially seed germination in arid and semiarid regions in iran. turf grasses are highly dissipation in areas associated with saline soils and/or saline irrigation water. in order to study the effects of salinity on turf grasses germination, an experiment was con...

Fructification and yield of the edible mushrooms Pleurotus pulmonarius and Stropharia rugosoannulata are clearly enhanced when wheat straw is supplemented with 30% Lolium perenne grass chaff. The bioactive compound in the methanol extract of grass chaff was identified as beta-adenosine. In vitro biological activity tests showed that 0.012 mg of beta-adenosine per ml of medium stimulated earlier...

Wheat-Agropyron cristatum 7P disomic addition line Ⅱ-5-1, derived from the distant hybridization between A. cristatum (2n = 4x = 28, PPPP) and the common wheat cv. Fukuhokomugi (Fukuho), displays numerous desirable agronomic traits, including enhanced thousand-grain weight, smaller flag leaf, and enhanced tolerance to drought. In order to transfer these traits into common wheat, Ⅱ-5-1 was induc...

—Unsuccessful oak (Quercus spp.) regeneration could result in losses of the rarer portions of the midwestern North American oak savanna region, including the tall grass oak savannas. We undertook this study to understand the effects of restoration on promoting growth of naturally occurring Q. alba seedlings in a degraded tall grass oak savanna in Iowa, USA. Initial restoration efforts, which in...
