forage species in mixtures are extensively grown worldwide nowadays, particularly as a step towards sustainable agriculture, however, information on this topic is scanty in our country. thus a 2-year (2001-2003) field experiment was conducted to determine the forage yield, botanical composition, as well as competition of some forage grasses and legumes as mono and dual cultures combinations at ...

Two in situ protein disappearance experiments were conducted to determine disappearance rates of leaf protein fractions and characterize individual leaf protein fractions that escaped ruminal degradation. Fresh leaf blades of two warm-season grasses, switchgrass (Panicum virgatum L.) and big bluestem (Andropogon gerardii Vitman), and one cool-season grass, smooth bromegrass (Bromus inermis Leys...

7-49 ABSTRACT Grass seedling establishment is dependent on adventitious root development. However, evaluating the establishment status of a seeding by excavating a population of seedlings and determining root morphology is difficult and generally will not be undertaken. Based on both field and greenhouse studies we have found that root and shoot morphological development is closely related with...

Cells of the terrestrial plant species bromegrass (Bromus inermis L.) are not naturally adapted to withstand the hydrostatic pressures encountered in aquatic environments. However, after treatment with the natural plant growth hormone abscisic acid (75 micromolar), bromegrass cells survived a hydrostatic pressure of 101.3 megapascals, approximating the limits of ocean depth (10,860 m). The incr...

Development of new tillers in smooth bromegrass is largely determinant, with synchronized elevation and Smooth bromegrass (Bromus inermis Leyss.) is poorly adapted to elongation of new apical meristems above the soil surmanagement-intensive rotational grazing because of slow and limited regrowth potential. In an effort to find existing germplasm with tolerface (Krause and Moser, 1977). Cutting ...

Germplasm managers at the Western Regional Plant Introduction Station (WRPIS) have focused on improving seed regeneration in forage and turf grass species through studies of diversity maintenance, using isozyme markers in annual ryegrass (Lolium multiflorum Lam.) and through studies of pollen isolation, using strains of dominant pubescent and recessive glabrous smooth bromegrass (Bromus inermis...

Near infrared reflectance spectroscopy (NIRS) has recently become a potentially valuable and reliable tool for analyses of plant samples in forage-breeding programs. The success of NIRS is dependent on identification of appropriate and reliable selection criteria and development of reliable calibration. The objectives of this study were to develop and compare NIRS analysis equations for the in ...

Interseeding annual warm-season grasses may increase forage and pasture productivity. From 2017 to 2019, we conducted a grazing experiment that examined smooth bromegrass (Bromus inermis Leyss.) responses interseeding sorghum-sudangrass [Sorghum bicolor (L.) Moench × S. ssp. drummondii (Nees ex Steud.) de Wet & Harlan]. The had split-plot design with six main plots each containing two, 0.60-ha ...

Development of new tillers in smooth bromegrass is largely Smooth bromegrass (Bromus inermis Leyss) is poorly adapted to determinant, with synchronized elevation and elongamanagement-intensive rotational grazing because of slow and limited tion of new apical meristems above the soil surface regrowth potential.

Information on the tiller development of hybrid bromegrass (Bromus inermis × Bromus riparius Rehm) is limited. The objective this study was to evaluate effect clipping frequency at vegetative and reproductive stages concentrations sugars ‘AC Knowles’ compared ‘Kirk’ crested wheatgrass (Agropyron cristatum L.). This experiment conducted in greenhouse using tillers vernalized plants dug from fiel...
