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...

Tall fescue grass cultivars with or without endophytes were evaluated for their susceptibility to Meloidogyne incognita in the greenhouse. Tall fescue cultivars evaluated included, i) wild-type Jesup (E+, ergot-producing endophyte present), ii) endophyte-free Jesup (E-, no endophyte present), iii) Jesup (Max-Q, non-ergot producing endophyte) and iv) Georgia 5 (E+). Peach was included as the con...

Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) is often managed with a cutting height ranging from 70 to 100 mm in ornamental lawns. Some autonomous mowers have been specifically designed maintain mowing the same range. Generally, operate by following random trajectories, and substantial overlapping needed obtain full coverage of working area. In case tall grass, this may cause lodgin...

Tall fescue and other non-native perennial cool-season grasses (such as orchardgrass, timothy, bromegrasses, and bluegrass) provide poor wildlife habitat. Native warm-season grasses (nwsg), especially big and little bluestem, indiangrass, and switchgrass, have been promoted to replace non-native cool-season grasses and enhance quality early succession habitat. Initially, problems associated wit...

Measurements of CO(2) exchange at varying O(2) concentrations in seven grass species of the Laxa group of Panicum and activities of five photosynthetic enzymes were compared to values obtained for these characters in a cool season C(3) grass, tall fescue (Festuca arundinacea Schreb.) and a C(4) grass, P. maximum Jacq. Plants were divided into three groups on the basis of the inhibition of appar...

M A N Y characters which would-be desirable in cultivated crops are known to exist in related species and genera. The most striking examples of such characters are the resistances to various diseases. Where hybridization can be achieved between the pertinent genera, attempts have been made to transfer genes for these desired characters into the genome of the cultivated species. Partially for th...

Selenium (Se) is a potential soil contaminant in many parts of the world where it can pose a health risk to livestock and wildlife. Phosphate ore mining in Southeast Idaho has resulted in numerous waste rock dumps revegetated with forages to stabilize the dumps and support grazing. Alfalfa (Medicago sativa L.), smooth brome (Bromus inermis Leyss.), and western wheat grass [Pascopyrum smithii (R...

Heat stress transcription factors (HSFs) compose a large gene family, and different members play differential roles in regulating plant responses to abiotic stress. The objectives of this study were to identify and characterize an A2-type HSF, FaHsfA2c, in a cool-season perennial grass tall fescue (Festuca arundinacea Schreb.) for its association with heat tolerance and to determine the underly...
