Mutualistic fungal endophytes infect many grass species and often confer benefits to the hosts such as reduced herbivory by insects and animals. The physiological interactions between the endophytes and their hosts have not been well characterized. Fungal-secreted proteins are likely to be important components of the interaction. In the interaction between Poa ampla and the endophyte Neotyphodi...

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...

Five grass species (Dactylis glomerata L., Phleum pratense L., Lolium perenne L., Festuca arundinacea L. and the hybrid Felina (Lolium multiflorum L. × Festuca arundinacea L.)), commonly used in roughages for ruminants, were harvested at different maturities of primary growth (n = 60) and evaluated for contents of dry matter (DM), crude protein (CP), ash, crude fat, neutral detergent fibre (NDF...

The role of sewage sludge as an immobilising agent in the phytostabilization of metal-contaminated soil was evaluated using five grass species viz., Dactylis glomerata L., Festuca arundinacea Schreb., F. rubra L., Lolium perenne L., L. westerwoldicum L. The function of metal immobilization was investigated by monitoring pH, Eh and Cd, Pb, and Zn levels in column experiment over a period of 5-mo...

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...

1 We established monocultures and 16 unique mixed communities of 12 native grasses, legumes and non-N 2 -fixing forbs. We identified species having a greater or lesser yield in the mixed communities than expected from monoculture data as winners and losers, respectively. To test our hypothesis that performance of the subordinate species (losers) is mainly controlled by light availability, where...

Tall fescue [Lolium arundinaceum (Schreb.) Darbysh. syn. Festuca arundinacea Schreb.] and perennial ryegrass (Lolium perenne L.) are important perennial forage grasses utilized throughout the moderate- to high-rainfall temperate zones of the world. These grasses have coevolved with symbiotic fungal endophytes (Epichloë/Neotyphodium spp.) that can impart bioactive properties and environmental st...

The persistence and productivity of forage grasses, important sources for feed production, are threatened by climate change-induced drought. Breeding programs in search new drought tolerant grass varieties, but those still rely on time-consuming less consistent visual scoring breeders. In this study, we evaluate whether Unmanned Aerial Vehicle (UAV) based remote sensing can complement or replac...
