Tall fescue [Lolium arundinaceum (Schreb.)] is a cool-season perennial grass used in pastures throughout the Southeastern United States. The grass can harbor a shoot-specific fungal endophyte (Epichloë coenophiala) thought to provide the plant with enhanced resistance to biotic and abiotic stresses. Because alkaloids produced by the common variety of the endophyte cause severe animal health iss...
Two tall fescue [Lolium arundinaceum (Schreb.) Darbysh] forages, one an experimental host plant/endophyte association containing a novel endophyte that produces low or nil concentrations of ergot alkaloids (HM4) and the other a typical association of Kentucky 31 tall fescue and the wild-type endophyte (Neotyphodium coenophialum; E+), were autumn-stockpiled following late-summer clipping and fer...
Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) often forms a symbiotic relationship with fungal endophytes (Epichloë coenophiala), which provides increased plant performance and greater tolerance to environmental stress compared endophyte-free tall fescue. Whether this enhanced of exclusively results from the grass–fungus symbiosis, or symbiosis additionally in recruitment soil mic...
abstract the lack of water is the most important problem in extensive landscape especially turfgrass in arid and semi arid regions. the root responses in native and commercial grasses under drought stress were investigated. this experiment was in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...
Grass tetany is a nutritional disease of ruminants caused by low dietary Mg. Previous research has shown that early spring P-fertilization increases the leaf Mg concentration of tall fescue (Festuca arundinacea Schreb.) hay. However, little is known about how P-fertilization alters the mineral concentration of tall fescue under grazing. Our objective was to compare, under grazing, the Mg, K, Ca...
A historic profile of endophyte-induced tall fescue toxicosis is presented. A chronology of events is presented, beginning with the importance of finding Balansia-infected grasses in a tall fescue pasture in north central Georgia. This initial finding was followed by the discovery that another related endophyte was present in tall fescue and other major forage grasses. This species of endophyte...
Tall fescue (Festuca arundinacea Schreb.) is an open-pollinated, perennial, cool-season turf and forage grass species of great economic importance. The main problems of maintenance of tall fescue, and many other turfgrasses, are two severe fungal diseases: gray leaf spot caused by Magnaporthe grisea, and brown patch caused by Rhizoctonia solani. Three genes from various sources have been introd...
et al., 1981) and timothy (Phleum pratense L.; Braverman, 1966; Nielson and Dickson, 1958). In addition, Genetic resistance to stem rust (caused by Puccinia graminis several cultivars of perennial ryegrass (Lolium perenne Pers.:Pers. subsp. graminicola Z. Urban) could reduce the need for fungicides to control the disease in tall fescue [Lolium arundinaceum L.) with reduced susceptibility to ste...
There is an increase in awareness of the benefits of grass hay from an agronomic and nutritional perspective. The main cool season forage grass species adaptable to California are annual ryegrass, Italian ryegrass, perennial ryegrass, orchard grass and tall fescue. The main characteristics of these species along with attributes of different varieties are highlighted in this paper. The agronomic...
One of the main problems of Shiraz city’s green space is the change of color and visual quality of turf during cold months. Therefore, we aimed to evaluate tall fescue in order to find if it is suitable for replacement. This experiment was in the form of complete random blocks and it was done during two consecutive years. Each treatment had 4 repetitions. Data were analyzed using SPSS software,...
