In recent decade, establish and maintenance of turf grasses is faced with serious doubts due to reduction of precipitation and water resources. So, identification of drought-resistant native and rangeland species, and introducing them as turf grass not only is effective in reducing water consumption, but also help to preserve the genetic resources of the country. In order to evaluate the usabil...
The effect of substituting native grass with jengkol (Archidendron jiringa) by-product on fermentation characteristics, rumen microbial profile, methane production, and hydrogen balance using in vitro method was investigated. Seven treatments (different composition of native grass, jengkol peel, jengkol leaves, and concentrate) with five replications in a block randomized desi...
crested wheatgrass (agropyron cristatum (l.) gaertner.) is a potential source of low-maintenance turf species for use in areas with less water. the main goal of this study was to evaluate turf quality characteristics of 24 crested wheatgrass specimens collected from different locations of iran as low-maintenance turfgrass. the experimental design was a randomized complete block design with 3 re...
Within highway rights-of-way, native perennial grasses provide desirable services to support natural and human constructed ecosystems. However, native perennial grass establishment in annual grass dominated roadsides of semiarid and Mediterranean climates of the western United States requires specific cultural and chemical management treatments to control weeds. In 2004, field studies were cond...
Invasive grass weeds reduce farm productivity, threaten biodiversity, and increase weed control costs. Identification of invasive grasses from native grasses has generally relied on the morphological examination of grass floral material. DNA barcoding may provide an alternative means to identify co-occurring native and invasive grasses, particularly during early growth stages when floral charac...
Epichloë fungal endophytes are broadly found in cool-season grasses. The symbiosis between these grasses and Epichloë may improve the abiotic and biotic resistance of the grass plant, but some Epichloë species produce alkaloids that are toxic for livestock. Therefore, it is important to understand the characteristics of the grass-Epichloë s symbiosis so that the beneficial aspects can be preser...
A COMPLETE knowledge of the factors that contribute to the nutritive value of native grass and hay is of both practical and scientific value. Seasonal and environmental factors contribute largely to variations in the nutrient content of the grass, and other less well-defined factors apparently influence the availability of these nutrients in digestion. Factors associated with the physical chara...
Populations of the rare annual forb Amsinckia grandiflora may be declining because of competitive suppression by exotic annual grasses, and may perform better in a matrix of native perennial bunchgrasses. We conducted a field competition experiment in which Amsinckia seedlings were transplanted into forty 0.64-m 2 experimental plots of exotic annual grassland or restored perennial grassland. Th...
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...
