Among seed-transmitted cereal viruses the most important is Barley stripe mosaic virus (BSMV), infecting barley. Investigations on the occurrence of BSMV in Poland have been carried out in the Institute of Plant Protection in Poznań since 2000. The studies aimed at the evaluation of the BSMV distribution in plant material, the rate of its seed transmission in different barley cultivars and the ...

OBJECTIVE The hull attached to the barley kernel can be mechanically removed thus reducing the fiber content of the barley. This experiment was carried out to evaluate the effects of partial dehulling on the nutrient digestibility as well as the digestible energy (DE) and metabolizable energy (ME) content of barley in pigs. METHODS Two hulled barley samples (high fiber barley [HF] and low fib...

Abscisic acid (ABA) accumulates in seeds during the transition to the seed filling phase. ABA triggers seed maturation, storage activity, and stress signalling and tolerance. Immunomodulation was used to alter the ABA status in barley grains, with the resulting transgenic caryopses responding to the anti-ABA antibody gene expression with increased accumulation of ABA. Calculation of free versus...

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...

Barley lectin is synthesized as a preproprotein with a glycosylated carboxyl-terminal propeptide (CTPP) that is removed before or concomitant with deposition of the mature protein in vacuoles. Expression of a cDNA clone encoding barley lectin in transformed tobacco plants results in the correct processing, maturation, and accumulation of active barley lectin in vacuoles [Wilkins, T.A., Bednarek...

The objective of this study was to explore the potential of near-infrared spectroscopy for determining the compositional quality properties of barley as a feedstock for fuel ethanol production and to compare the prediction accuracy between calibration models obtained using a Fourier transform near-infrared system (FT-NIR) and a dispersive near-infrared system. The total sample set contained 206...

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...
