ABSTRACT Most barley cultivars are resistant to stripe rust of wheat that is caused by Puccinia striiformis f. sp. tritici. The barley cv. Steptoe is susceptible to all identified races of P. striiformis f. sp. hordei (PSH), the barley stripe rust pathogen, but is resistant to most P. striiformis f. sp. tritici races. To determine inheritance of the Steptoe resistance to P. striiformis f. sp. t...

Barley was brought to California by the Spanish padres via Mexico and was cultivated on mission lands since at least 1771 [7] . Until 1860, when it was surpassed by wheat, barley was the most important grain grown by the early American settlers in California [1] . It was the principle feed grain for livestock, and malting barley was also the basis for an early California export trade with Great...

Direct or indirect methods can be used to determine the DE and ME of feed ingredients for pigs. In situations when only the indirect approach is suitable, the regression method presents a robust indirect approach. Three experiments were conducted to compare the direct and regression methods for determining the DE and ME values of barley, sorghum, and wheat for pigs. In each experiment, 24 barro...

Little is known about the effect of management practices on net global warming potential (GWP) and greenhouse gas intensity (GHGI) that account for all sources and sinks of greenhouse gas (GHG) emissions in dryland cropping systems. The objective of this study was to compare the effect of a combination of tillage, cropping system, and N fertilization on GWP and GHGI under dryland cropping syste...

Cereals such as barley and wheat are unable to germinate under anoxic conditions. Data are presented on the utilization of the soluble sugars present in the dry seed of wheat and barley kept under strict anoxia, together with the status of the enzymes involved in the metabolism of carbohydrates. The amount of glucose, fructose, and sucrose decreases during the anaerobic treatment, indicating th...

Laboratory studies were conducted to examine the effects of different concentrations of wild barley (Hordeum spontaneum Koch.) shoot and seed extracts on germination and seedling growth of wheat (Triticum aestivum L.) and wild barley. In this study, all wild barley shoot extract concentrations (with exception of lowest concentration) significantly reduced wheat seed germination after 7 days. Sh...

in order to study the tolerance level of different wild barley (hordeum spontaneum) populations to clodinafop propargyl (topic®), a pot dose response experiment was conducted in a completely randomized design with three replications at ferdowsi university of mashhad greenhouse in 2009. cultivared barley (hordeum vulgare) and three wild barley populations (shiraz, boshroyeh, and torogh) were stu...

This paper discusses archaeobotanical remains of naked barley recovered from the Okhotsk cultural layers of the Hamanaka 2 archaeological site on Rebun Island, northern Japan. Calibrated ages (68% confidence interval) of the directly dated barley remains suggest that the crop was used at the site ca. 440-890 cal yr AD. Together with the finds from the Oumu site (north-eastern Hokkaido Island), ...

Commercial lentil screenings (LS) were substituted for barley grain and canola meal, and the resulting experimental diets (0, 12.5, 25 and 33% LS; 17±18% CP dry matter) were evaluated in situ and in digestibility and feedlot studies using Romanov Suffolk lambs. Mature Suffolk, Dorset and Rambouillet ewes were used to evaluate LS or whole barley as protein/energy supplements for ewes in mid-gest...

McCartney, D. H. and Vaage, A. S. 1994. Comparative yield and feeding value of barley, oat and triticale silage. Can. J. Anim. Sci. 74: 91-96. The yield and feeding value of barley (Hordeum vulgare 'Johnson'), oat (Avena sativa 'Calibre') and triticale (Triticosecale 'Carmen') silages were compared in a field study, a heifer growth trial (1 19 d in length, with four pens of eight Charolais cros...
