in this study, the effect of drought stress on morphological and physiological characteristics of wheatgrass and tall fescue was investigated in a factorial-split plot in time arrangement based on a completely randomized design with three replications. after turf establishment, half pots were exposed to drought stress and the half other were completely irrigated. based on the results tall fescu...

The lack of light and shadow created by the development of human artificial and shade of the trees in landscapes are the one of the main challenge facing the lawn as one of the main components of urban landscapes. In this study, the effects of different shade levels (0, 50, 70 and 90%) on the appearance and morphological characteristics of wheatgrass (Agropyron deserturumL.) and tall fescue (Fe...

a few information about the combined effects of different environmental stress on turfgrass physiology and growth is available. also, a separate study of environmental factors on plant cannot be a suitable model for natural conditions. this study was conducted to investigate the interactive effects of different levels of shade (0, 50, and 70%) and water treatments (well-watered and non-irrigate...

the objectives of this research were to study the varieties and relationships of yield and quality traits under two harvesting management procedures concerning forage dry matter (dm yield) and 5 quality traits such as dry matter digestibility (dmd%), water soluble carbohydrates (wsc%), crude protein (cp%), acid detergent fibre (adf%) and total ash in tall wheatgrass (agropyron elongatum). in th...

the objective of this research was to study the effects of phenological stages on yield and quality traits in 22 populations of tall wheatgrass agropyron elongatum. a split plot design was conducted using a complete randomized block with two replications in lorestan (borujerd), iran during 2007-2008. the genotypes were cut in five maturity stages as vegetation, stem elongation, heading date, an...

Halogeton (Halogeton glomeratus) is an invasive species that displaces Gardner's saltbush (Atriplex gardneri) on saline rangelands, whereas, forage kochia (Bassia prostrata) potentially can rehabilitate these ecosystems. Salinity tolerance has been hypothesized as the predominant factor affecting frequency of these species. This study compared relative salinity tolerance of these species, and t...

Broad phenotypic variations were induced in derivatives of an asymmetric somatic hybridization of bread wheat (Triticum aestivum) and tall wheatgrass (Thinopyrum ponticum Podp); however, how these variations occurred was unknown. We explored the nature of these variations by cytogenetic assays and DNA profiling techniques to characterize six genetically stable somatic introgression lines. Karyo...

Integrating use of seeded perennial cool-season grass pastures with native rangeland can increase available forage and provide a high plane of nutrition for grazing livestock. Our objective was to compare performance of yearling beef heifers grazing native rangeland with those grazing an integrated system that included seeded forages. Twice-replicated, 3-ha pastures seeded to either ‘Rosana’ we...
