Comparsion of digestion and particle-associated bacteria after in situ incubation of different barley varieties in the rumen of cattle
The chemical composition of barley grain, including the structure of starch, can vary among barley varieties and result in different digestion efficiencies. It is not known if compositional differences in barley can affect the particle-associated bacteria (PAB) involved in digestion. Therefore, the …

Hull, ferulic acid, para-coumaric acid content and particle size characteristics of various barley varieties in relation to nutrient availability in ruminants
The fibrous barley hull is the main reason for barley’s low available energy relative to corn. Barley grain contains hydroxycinnamic acids (mainly ferulic acid (FA) and ñ-coumaric acid (PCA)) which are cross-linked to polysaccharides, therefore, limit cell wall degradability in the rumen. Paricle …

Location of genes for resistance to Puccinia hordei otth. in the barley varieties Sudan and Reka 1 as determined by means of translocation stocks
… to leaf rust Puccinia hordei Otth. race 4 in two varieties of barley to the correct chromosome pair by means of crossing with nine translocation stocks. The varieties Sudan (C.I.6489) and Reka 1 (C.I.5051) were crossed with the following translocation stocks: 5051-2 (a-b), 5059-5 (a-e), 5030-2 …

Identification and generation of new germplasms in barley with increased tolerance to waterlogging
The ability to maintain high yields for barley production in Ireland is crucial for the indigenous brewing industry. However, high yields are threatened by global climate change, as Ireland is predicted to have increased flooding events. In consequence, the identification and development of barley …

Assessment of stress-induced and developmentally-induced DNA methylation changes in barley (Hordeum vulgare L.)
… functional and crop improvement studies. We used barley as a plant model, and salinity as a stress model, to study methylation markers that discriminate the plant tissues and that are specific to salinity stress. This choice presented the advantage of using a crop plant with a reference genome …

The Effect of Split Nitrogen Fertilization on Yield, Quality, and Nitrogen Use Efficiency of Spring Barley Grown on Two Different Soil Types in Iceland
… using two different soil types and two spring barley varieties, Smyrill (six-row) and Kría (two-row), to study the effects of different N split applications on growth, grain yield, grain protein content (GPC), and NUE. Treatments included single fertilization at sowing, early booting, and/or …

The enzymomology of the malting, milling, mashing and fermentation processes within the scotch malt whisky industry
The wort from the malted barley used in the Scotch Malt Whisky process must be obtained solely from the activity of enzymes associated with the malted barley. Little or no detailed studies have been reported on the complex mixtures of enzymes found in malted barley, nor their subsequent activity …

Genetic diversity of the HvFT1 flowering gene in Nordic spring barley (Hordeum vulgare L.)
… important role in flowering time regulation in barley (Hordeum vulgare L.). It functions as a central integrator for signals of the vernalization, photoperiod and circadian clock pathways and promotes flowering. This is of interest for barley breeders on Iceland, who aim to produce early …

Developing Low-GN and GN-zero Winter Malt Barley for the Eastern United States
… (GN) are carcinogenic precursors produced by barley as a natural defense against insects. The most common GN in barley, epiheterodendrin (EPH), contains a cyanide group that, when combined with heat and copper during distillation, forms ethyl carbamate (EC), a known carcinogen. While GN-zero …

Genomic selection for accelerated barley breeding
… with the increasing demand for new and improved barley varieties, commercial interest in novel breeding techniques which improve efficiency is high. With a growing population and a range of evolving demands placed on crop production by a more variable climate, breeders need new methods to breed …

The effect on yield of cross-breeding varieties of barley
… compared with self fertilized seed of the same varieties. It was originally purported to make these tests with both wheat and barley. However, owing to unfavorable greenhouse conditions the wheat plants bloomed very poorly and the crosses made set very little seed so the wheat was dropped and …
