BACKGROUND Archaeobotanical samples of barley (Hordeum vulgare L.) found at Qasr Ibrim display a two-row phenotype that is unique to the region of archaeological sites upriver of the first cataract of the Nile, characterised by the development of distinctive lateral bracts. The phenotype occurs throughout all strata at Qasr Ibrim, which range in age from 3000 to a few hundred years. METHODOLO...

The study was carried out to determine the gel pasting properties of barley (Hordeum vulgare L. cv. Geoncheonheugbori) as affected by different proton beam irradiation. The λmax, blue value, and amylose content were significantly associated with increasing proton beam irradiation. The pasting time in barley flour irradiated with proton beam ranged 0.09 to 0.16 min shorter than nonirradiated bar...

A study was conducted in an eight-arm radial maze to determine if cattle with various foraging experiences could facilitate location of feeding sites by other cattle. Heifers assigned as "followers" (n=24) were initially trained to expect straw at the end of each arm. Initial training of heifers assigned as "leaders" (n=12) differed based on the three following treatments:(1) no-experience, (2)...

In their classic study of the enzymes involved in the mobilization of stored carbohydrate reserves in barley, Brown and Morris (3), in 1890, noted that the excised barley embryo formed a large quantity of starch when floated on water for a few hours. More recently investigators (2, 4, 5) working with excised barley embryos appear to have ignored or neglected this important biochemical transform...

OBJECTIVE Two experiments were conducted to determine the content of digestible energy (DE) and metabolizable energy (ME) as well as the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) in barley grains obtained from Australia, France or Canada. METHODS In Exp. 1, 18 growing barrows (Duroc×Landrace×Yorkshire; 31.5±3.2 kg)...

BACKGROUND Archaeological evidence has revealed that barley (Hordeum vulgare) is one of the oldest crops used by ancient farmers. Studies of the time and place of barley domestication may help in understanding ancient human civilization. SCOPE The studies of domesticated genes in crops have uncovered the mechanisms which converted wild and unpromising wild species to the most important food f...

The Genome-Wide Association Studies approach was used to detect Quantitative Trait Loci associated with tocochromanol concentrations using a panel of 1,466 barley accessions. All major tocochromanol types- α-, β-, δ-, γ-tocopherol and tocotrienol- were assayed. We found 13 single nucleotide polymorphisms associated with the concentration of one or more of these tocochromanol forms in barley, se...

The impact of the protein content of feed barley on the costs of feeding beef, dairy cattle, and swine in Montana is evaluated. A model of least-cost feed rations is constructed to analyze the marginal value of additional protein content in feed barley. The results indicate that increasing the protein content of feed barley above 12% will not substantially increase the value of barley to feeder...

Barley contains approximately 10% dietary fiber and is easily cooked with rice, the dominant cereal in Japan, to increase the intake of dietary fiber. This research involved three experiments to examine the influence of barley on blood lipids in human subjects. All subjects received a boiled barley-rice (50/50 w/w mix) supplement two times per day in place of rice for 2 or 4 weeks. In the normo...

Variation in the currently recognized species, Barbatula nuda (Bleeker 1865), from North China was studied, and three distinct species are identified: B. nuda, B. toni, and B. gibba sp. nov.. The name B. nuda is presently misapplied; this species is distinct from B. toni, a species widely distributed in Northeast China, and occurs only in the Liao-He basin of Liaoning Province and the Tumen-Jia...
