Adaptation and Establishment Meadow fescue prefers deep, rich soils, and while surviving in wet soils, it cannot tolerate flooding. It will survive under dry conditions but is more sensitive to drought than many other grasses. It can be grown in areas suitable for timothy, and is considerably more winter hardy than tall fescue in northern environments. Meadow fescue is closely related to both t...

Tall fescue (Festuca arundinacea Schreb.) infected with the endophyte Neotyphodium coenophialum ([Morgan-Jones and Gams] Glenn, Bacon, and Hanlin) causes fescue toxicosis in cattle grazing the forage, but effects of the endophyte were considered to be abated soon after removal of the animals from pastures. Tasco-Forage, a proprietary extract from the brown seaweed Ascophyllum nodosum, is a know...

Tall fescue (Schedonorus phoenix (Scop.) Holub) is a cool-season bunchgrass that grows throughout the eastern half of the United States and in the Pacific northwestern region of the country. It is estimated that over 90% of tall fescue pastures are infected with the fungal endophyte Neotyphodium coenophialum (Bacon and Siegel, 1988; Glenn et al., 1996). Tall fescue is native to Europe and was f...

Eight cultivars of tall fescue (Lolium arundinaceum Schreb., S.J. Darbyshire 1⁄4 Festuca arundinacea Schreb.), Barcel, Kenhy, Kentucky-31, Missouri-96, Mozark, Stargrazer, C-1 (an experimental selection), and HiMag, were sampled at 2-h intervals during daylight on four cutting dates. Cultivars varied in concentrations of carbohydrate fractions but accumulation rates were not different. Daily me...

Grass selections including 10 zoysiagrasses, 18 paspalums, 34 Bermuda grasses, tall fescue, creeping red fescue, and perennial ryegrasses with and without endophyte were evaluated for potential resistance to fall armyworm, Spodoptera frugiperda (J. E. Smith), larvae. Laboratory evaluations assessed the degree of antibiosis among >70 grass lines to first-instar fall armvworms. When all parameter...

A 2-yr pen experiment was conducted using 12 different crossbred Angus steers each year to determine if short-term changes in prolactin concentrations, body temperature, and vasoconstriction reflect recovery from fescue toxicosis after steers that previously grazed toxic endophyte (Neotyphodium coenophialum)-infected Kentucky 31 tall fescue [Lolium arundinaceum (Schreb.) Darbysh] are placed on ...

Perennial ryegrass (Lolium perenne L.) and tall fescue (Festuca arundinacea Schreb.) are two major turfgrass species in the United States. Their improvement via biotechnology approaches depend on the tissue culture response, particularly in vitro plant regeneration. To understand more of the regeneration event, scanning electron microscopy was performed and somatic embryogenesis was revealed in...

A variety of alkaloids, N-containing season perennial forage naturally infected with an endophyte, Neotyphodium coenophialum Glenn, Bacon, & Hanlin, which produces ring structures, are produced in the t...

Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated that it contains different species from the genus Festuca and allowed their rapid classification into the three major morphotypes (Continental, Mediterranean and Rhizomatous...

Mutual relationship between pasture grasses and Neotyphodium fungal endophytes is of great importance in grass improvement. Two endophyte containing tall fescue genotypes (75 and 83) and their endophyte free ramets were used in this study. Endophytes were isolated from tall fescue genotypes 75 and 83 and used in three methods of inoculation including Latch and Christensen approach, insertion of...
