“…protein concentrations. This was in agreement with previous findings where a significant negative relationship between starch and protein was reported in a variety of HB genotypes (Bhatty 1999) or for Condor HB grown at different locations (Edney et al 1992). Amylose concentration (dry starch basis) was 0% for HB340, 1.0% for SB94022, 4.5% for CDC Candle, 5.0% for SB94917, 7.0% for SR93139, 25.4% for CDC Dawn, 24.6% for SB90354, 36.4% for CDC 92-55-08-31, and 41.7% for CDC 92-55-06-48.…”

Cereal Chem. 77(2):140-144Nine hull-less barley (HB) containing waxy (0-7% amylose), normal (≈25% amylose), or high amylose (≈42% amylose) starch with normal or fractured granule make-up and 4-9% (1→3)(1→4)-β-D-glucans (βglucan) were pearled to remove 70% of the original grain weight in 10% intervals. The pearled fractions were analyzed for β-glucan distribution within HB grain. Protein content of the pearled fractions indicated that the three outermost fractions contained pericarp and testa, aleurone, and subaleurone tissues, respectively. For all HB, β-glucan and acid-extract viscosity were very low in the outermost 20% of the kernel. For low βglucan HB, β-glucan content was the greatest in the subaleurone region and declined slightly toward inner layers. For high β-glucan HB, however, more than 80% of grain β-glucan was distributed more evenly throughout the endosperm. Acid extract viscosity was significantly (P < 0.01) correlated with total (r = 0.75) and soluble (r = 0.87) β-glucan content throughout the kernel of all HB. Growing conditions, location and year, had significant effects on the concentration of protein, starch and β-glucan. However, protein, starch, and β-glucan distribution patterns were not affected by growing conditions. The difference in β-glucan distribution between low and high β-glucan HB may explain the difference in milling performance of HB with low or high β-glucan.Publication no. C-2000-0210-04R.

“…In hull-less varieties, the hull becomes detached during threshing, which results in less fiber and more digestible feed for livestock than hulled varieties (Edney et al 1992). This can result in seed being more vulnerable to mechanical damage and invasion by fungi during storage (White et al 1999).…”

R. 2005. Variable crop plant establishment contributes to differences in competitiveness with wild oat among wheat and barley varieties. Can. J. Plant Sci. 85: 771-776. Field experiments were conducted at three locations in Alberta to determine the relative competitiveness with wild oat (Avena fatua L.) of three hard red spring (HRS) and three Canada prairie spring (CPS) wheat (Triticum aestivum L.) varieties and a semidwarf hull-less barley (Hordeum vulgare L.) (Falcon), and normal height general purpose barley (AC Lacombe). Crop variety significantly affected crop yield loss, wild oat shoot dry weight and wild oat seed yield (competitive indicators). AC Lacombe barley was consistently more competitive than Falcon barley or any of the wheat varieties, while the HRS wheat varieties were mainly more competitive than the CPS varieties. Falcon barley was generally similar in competitiveness to the CPS wheat varieties. Differences among varieties in crop plant density at establishment correlated significantly with the competitive indicators suggesting that this factor contributed to the differences in competitiveness among the varieties. Crop density tended to be higher with the more competitive AC Lacombe barley and HRS wheat varieties than with the less competitive Falcon barley and CPS wheat varieties. Variety and seeding rate did not interact significantly but intentionally increasing the seeding rate improved the competitiveness of all varieties. . La variété a une incidence significative sur la réduc-tion du rendement, sur le poids sec des pousses de folle avoine et sur le rendement grainier de cette dernière (indicateurs de compétitivité). L'orge AC Lacombe est toujours plus compétitive que l'orge Falcon ou que les variétés de blé, mais les cultivars de BRVP sont passablement plus compétitifs que ceux de BPPC. L'orge Falcon est généralement aussi compétitive que les variétés de BPPC. La variation de la densité du peuplement à l'établissement de la culture présente une corrélation significative avec les indicateurs de compétitivité, signe que ce paramètre concourt aux différences de compétitivité entre les variétés. La densité du peuplement a tendance à être plus élevée chez l'orge AC Lacombe et chez les variétés de BRVP, plus compétitives, que chez l'orge Falcon et les variétés de BPPC, moins compétitives. La variété et la densité des semis n'interagissent pas de manière significative, mais l'accroissement délibéré de la densité des semis rehausse la compétitivité de toutes les variétés.

“…26 The higher content of protein observed in naked barley samples has been reported before, as well as the lower content of dietary ®bre. 8,27 The level of dietary ®bre in naked barley samples, however, has been shown to be about 25% higher than in pearled covered barley samples. 28 The presence of hull in the covered barley samples probably also accounts for the larger proportion of unextractable ®bre/extractable ®bre in these samples compared to naked samples.…”
