A. and Savard, M. E. 2013. Taylor barley. Can. J. Plant Sci. 93: 969–977. Taylor is a hulless two-row spring barley (Hordeum vulgare L.) cultivar with malting quality potential, and is one of the first hulless cultivars to be registered for that purpose in Canada. This line was developed in 2001 from a CDC Freedom/Rivers cross by in vitro selection using three Fusarium derived mycotoxins in the medium of an anther culture system. Taylor was evaluated in the Western Cooperative Hulless Barley Registration Test (2006–2008), and in pilot-scale malting trials (2007–2008), before being registered as HB705 in 2009 with its name changed to Taylor in 2011. In extensive evaluation in Fusarium head blight (Fusarium graminearum Schwabe) nurseries from 2002 to 2011, Taylor consistently showed low deoxynivalenol concentration.

K., Rossnagel, B. G. and Harvey, B. L. 2011. Norman barley. Can. J. Plant Sci. 91: 1105–1113. Norman is a hulled two-row spring malting barley (Hordeum vulgare L.) cultivar derived from the cultivar CDC Kendall that was widely grown in western Canada and utilized commercially by the malting and brewing industry. Developed in 2000 by in vitro selection using deoxynivalenol mycotoxin in the medium of an anther culture system, Norman was evaluated in the Western Cooperative Two-row Barley Registration Test in 2005 and 2006, and the malting and brewing industry Collaborative Malting Barley Trials in 2006 and 2007, before being registered in 2009. Norman was also evaluated extensively for deoxynivalenol concentration in fusarium head blight (Fusarium graminearum Schwabe) nurseries from 2001 to 2009. Norman accumulates 25 to 30% less deoxynivalenol than its parent cultivar, CDC Kendall, but is similar in all other traits including malting quality.

Three spring barley (Hordeum vulgare L.) and four annual ryegrass (Lolium multiflorum Lam.) types were intercropped to evaluate the potential yield and quality of forage which can be produced under irrigation in southern interior B.C. All treatments were intercrops; when barley cultivar effects are described they are averaged over the ryegrasses and vice versa. Barley cultivars differed in grain maturity. Ryegrass cultivars included diploid and tertraploid Italian and Westerwolds types. Intercrops including late grain maturing barley cultivars (Samson and Virden) increased the yield of the first silage cut (both by 25% over 2 yr) compared to Diamond, a medium-maturing cultivar adapted to the area. Intercrops containing the semi-dwarf barley, Samson, produced more digestible forage including higher in vitro digestible dry matter (IVDDM) and lower ADF and lignin. Annual ryegrass yield in the first cut intercropped with Samson was almost twice that with either Diamond or Virden, showing that Samson barley is less competitive. Second-cut yield (ryegrass regrowth) was greater for tetraploid than diploid annual ryegrasses. Yields of fall pasture (cuts 3 and 4) were similar among ryegrass cultivars. Cuts 2 and 3 (ryegrass only) of Italian ryegrasses had superior quality (higher IVDDM and protein; and lower ADF, lignin, and NDF) to Westerwolds ryegrassses, but all cultivars had similar quality in the late fall (Cut 4). It was concluded that a range of barley and annual ryegrass cultivars can be successfully intercropped to produce forage in south central B.C.Key words: Intercropping, barley annual ryegrass, forage yield and quality

Persian Clover

In the interior of British Columbia, spring barley (Hordeum vulgare L.) and Italian ryegrass (Lolium multiflorum var. italicum Beck.) are intercropped with fertilizer N as a 1-yr break before reseeding irrigated alfalfa (Medicago sativa L.). Persian clover (Trifolium resupinatum L.) was seeded with barley and ryegrass or only ryegrass to determine its effect on seasonal yield and forage nutritive value. All species mixtures were grown with and without a total of 200 kg ha−1 of N to compare N2 fixation by Persian clover with N fertilizer. Averaged over 2 yr, adding Persian clover to barley-ryegrass provided a total yield that was 96% of that obtained by adding fertilizer N to barley-ryegrass. Second cut yield averaged 58% more with clover than with N. However, the grasses yielded more than the grasses with added clover in the third cut. Adding clover to ryegrass provided 94% of the total yield of adding N fertilizer. Persian clover was higher in crude protein and in vitro digestibility of dry matter than ryegrass, so adding clover tended to improve the nutritive value of mixtures. This was most obvious without N, where Persian clover accounted for more of the total forage produced. The study shows that Persian clover is a valuable addition to barley-ryegrass mixtures; it reduces fertilizer needs, improves mid-season yield and improves forage nutritive value.

Background and Objective. Qingke (Tibetan hulless barley, Hordeum vulgare L.) contains a high content of β-glucan among all the cereal varieties. Although β-glucan has multiple physiological functions, the physiological function of qingke β-glucan was few studied. In this study, the β-glucan was isolated, purified, determined the structural characterization, and measured the inhibitory activity to enzymes correlating blood sugar and lipid. Methods. β-Glucan was isolated from enzymatic aqueous extract of qingke by using deproteinization, decolorization, DEAE-52 column chromatography, and sepharose CL-4B agarose gel column chromatography. The structure of the β-glucan was determined using FT-IR and 13C-NMR spectra analysis, and molecular mass by use of HPSEC-dRI-LS. The kinematic viscosity was measured. The inhibitory effects of this β-glucan on four enzymes were investigated. Results. This β-glucan had a uniform molecular weight of 201,000 Da with β-(1⟶4) as the main chain and β-(1⟶3) as a side chain. The β-glucan presented a relatively strong inhibitory activity on α-glucosidase, moderate inhibition on invertase, and a weak inhibition on α-amylase, whereas it did not inhibit lipase. Conclusion. The study indicates that the enzymatic β-glucan from qingke has the potential as natural auxiliary hypoglycemic additives in functional medicine or foods.

Trichothecene, a factor of aggressiveness of Fusarium graminearum in wheat fusarium head blight (FHB), was evaluated in an anther co-culture assay for the regeneration of doubled haploid (DH) lines with reduced mycotoxin accumulation. A Fusarium graminearum culture filtrate and a defined mixture of purified trichothecenes were compared with a control treatment in two F1-derived microspores populations. Frontana and Katepwa were the FHB resistant and intermediate resistant sources, respectively, and the cultivar Norseman was the FHB susceptible parent. A preliminary evaluation of the subpopulations of DH lines, using the point inoculation method in the greenhouse, showed selection effects for FHB resistance in the trichothecene co-cultured Frontana/Norseman subpopulation only. Three years of field evaluation using the spray inoculation method revealed that the DH subpopulation from the F1 hybrid Frontana/Norseman co-culture in the presence of trichothecenes accumulated consistently less deoxynivalenol (DON) in the grain than the control subpopulation. The FHB symptoms were also significantly reduced for 1 yr (2001) in the same subpopulation. This subpopulation showed increased test weight, plant height and a 1.1-d delay in heading date when compared with the control subpopulation, under disease pressure. A trichothecene co-cultured DH subpopulation from Katepwa/Norseman also had a significantly lower DON content for 1 yr.

Anti-Listeria bacterial starters are highly demanded by the meat industry. Novel bioprotective anti-Listeria starters were searched among Lactobacillus species strains isolated from artisanal sausages. The screening confirmed that anti-Listeria activity is a strain-specific property and yielded only 1 strain (of 36) exhibiting a satisfactory level of inhibition, L. delbrueckii WC0286. This strain was compared with two commercial bioprotective starters, SafePro B-SF-43 and SafePro B-LC-20, in a model simulating in vitro the first step of the fermentation process. The presence of the bioprotective starters did not modify the pH in such a way that could affect the safety or organoleptic properties of the product. Both SafePro B-SF-43 and SafePro B-LC-20 effected an important reduction of Listeria counts (0.56 and 0.72 log CFU g−1, respectively, in 72 h), while the anti-Listeria effect of L. delbrueckii WC0286 was minor (0.15 log CFU g−1). These results discouraged the utilization of L. delbrueckii WC0286 for a challenge test in a pilot salami production, in favor of the best-performing bioprotective starter, SafePro B-LC-20. The test confirmed that SafePro B-LC-20 did not alter the acidification trend of sausages and was capable of inhibiting Listeria, which decreased by 1.21 log CFU g−1. This information is relevant to address research activity toward the development of new bioprotective starters. The data herein presented demonstrate that the efficacy in Listeria control of potentially bioprotective bacterial starters requires further validation in real meat matrixes, possibly by using in vitro meat fermentation experiments to narrow down the list of candidates before pilot scale challenge tests.
