Activity Distribution

In this study, three pearling fractions, namely bran, dehulled grains and pearled grains, derived from fourteen hulled and one hull-less Greek barley cultivars (Hordeum vulgare L.), were analyzed for the protein, ash, β-glucan, phenolic compounds and tocols contents. High variations appeared in the bioactive contents across the barley cultivars and fractions as well. The protein and ash contents decreased from the outer to the inner layers, whereas β-glucans presented an inverse trend. The highest protein and β-glucan contents were in the hull-less cultivar; however, one hulled cultivar (Sirios) exhibited similar β-glucan content, while another (Constantinos) had even higher protein content. The results also revealed that functional compounds were mainly located in bran fraction. Similar trends were also noted for the antioxidant activity. Ferulic acid was the primary phenolic acid in all fractions, followed by sinapic and p-coumaric acids that were dominant in bound form. However, oligomeric flavonoids, such as prodelphinidin B3, catechin, and procyanidin B2, were more abundant in free form. Overall, this study highlights that different barley cultivars can provide pearling flour fractions of varying composition (nutrients and bioactives), which have the potential to serve as nutritionally valuable ingredients in formulations of cereal-based functional food products.

A brief historical sketch of the classification of barley (Hordeum vulgare L.) cultivars is presented along with reference to key reviews on this subject. Characters, utilized in the comprehensive study on the barley cultivars of North America by Aberg and Wiebe (U.S. Department of Agriculture Technical Bulletin 942), were subjected to a series of phenetic character analyses using an information theory model and a spatial autocorrelation model. The ranking of the 48 characters in order of their importance (for classification and identification purposes) from the character analysis by information theory was compared with the previous rating of characters made by Aberg and Wiebe and was found to differ significantly. Numerous trials of character analysis by spatial autocorrelation using various Minkowski distances, setting various values among three parameters, never yielded results comparable with those obtained by Aberg and Wiebe. Among those trials, a few combinations of values for the three parameters (X, Y, and Z) yielded results comparable with those obtained with character analysis by information theory. Those same combinations of values were found by Estabrook and Gates (Taxon, 33: 13–25) in their study of Banisteriopsis in 1984, where they also developed the method of character analysis by spatial autocorrelation. Kernel weight was found to be the most important character.

Diploid Level

Cells of haploid barley embryos (Hordeum vulgare L. 'Bruce', 'Perth', and 'Klages') and callus cells originating from embryos were cytophotometrically examined to determine the ploidy level. Specific embryo tissues regularly exhibited predictable ploidies and smaller embryos had a higher percentage of haploid cells than larger embryos of the same age. The predominantly haploid cells of the scutellar epidermis of the embryo initiated callus which generally, at least initially, was haploid. Monitoring of the ploidy evolution of these haploid calli showed that over a 6-month period each line exhibited its own unique rate of polyploidization, although lines of the same cultivar showed similar trends. Accumulation of cells at the diploid level was often a characteristic of these cultures.

The number of adventitious roots of two- and six-row barleys (Hordeum vulgare L.) grown under irrigation at Bozeman, Montana in 1970 and 1971, was related to yield and other agronomic characteristics. Adventitious roots were counted shortly before heading and at maturity and correlated with 15 agronomic characteristics. Adventitious root number was not correlated with yield of barley, except for two out of six cases in two-row barley. Roots per tiller, per plant and per square metre were all positively correlated with each other. The number of kernels per spike increased as roots per tiller increased but decreased with a high number of tillers per plant. Kernel plumpness and numbers of tillers were negatively correlated in two-row barley, but not in six-row barley. Cultivars differed significantly in yield and adventitious root number. Six-row barley had more roots per tiller but fewer tillers per square metre than two-row barley. Roots per tiller and roots per square metre measurements had the best repeatability between years for six-row barley, but no root measurements were consistent over years for the two-row type. Tillers per plant measurements for both two-row and six-row barleys and tillers per square metre for just two-row barley were consistent over years. Tiller and root number interact and are usually positively related. The genetic variation for root number shown here could be used in crosses for selection of superior genotypes.Key words: Barley, Hordeum vulgare, adventitious roots, subcrown internode, yield components, seeding rate

Acid Detergent Fibre

Barley (Hordeum vulgare L.) is a major feed in the Maritime region of Canada, but information on the chemical composition of barley cultivars grown in the Maritimes is lacking. Therefore, a study was undertaken to determine if starch, protein, neutral-detergent fibre (NDF), and acid-detergent fibre (ADF) of barley vary from region to region in Canada and to determine if barley cultivars that originated from Eastern Canada exhibit different chemical composition than those that originated from Western Canada. The chemical composition of two-row and six-row, covered and hulless, and feed and malting cultivars were also compared. Seventy-five cultivars were tested in eight environments (i.e. Charlottetown, Ottawa, Brandon, and Bentley in 1991 and 1992). These cultivars were classified into eight classes in four comparisons: eastern vs. western, two-row vs. six-row, hulless vs. covered, and feed vs. malting. Charlottetown grains were relatively low in protein, high in starch, and intermediate in NDF and ADF in comparison with grains produced at the other three locations. This suggests that more research in cultivar development and crop management is needed to increase the protein concentration of barley in the Maritimes. On average, two-row cultivars contained more starch and less fibre than six-row cultivars. Eastern two-row cultivars contained more protein than western two-row cultivars. As expected, hulless barleys contained more starch and protein, but less fibre than covered barleys. Canadian barley cultivars exhibited considerable variation in chemical composition. The cultivar x environment interaction was much smaller than the cultivar effect. Therefore, it is important to identify barley cultivars with high nutritional quality for use in commercial production. Key words: Barley, Hordeum vulgare L., cultivars, starch, protein, fibre

Yield And Yield Components

A field experiment was carried out to study the influence of sowing times on yield and yield components of barley (Hordeum vulgare L.). Seeds of four barley cultivars (BB 1, Karan 19, Karan 163 and Karan 351) were sown with four sowing times (5 November, 17 November, 29 November and 11 December). Most of the yield and yield components were significantly highest in 17 November sowing. Among the cultivars most of the characters showed their highest values in BB 1 and the lowest in Karan 19. Harvest index was found highest in Karan 351 and lowest in BB 1. Key words: Barley, Sowing time, Yield.   doi: 10.3329/jbs.v15i0.2154   J. bio-sci. 15: 139-145, 2007

Ustilago Hordei

Virulence of Ustilago hordei (Pers.) Lagerh. and U. nigra Tapke on the barley (Hordeum vulgare L.) cultivars Keystone and Conquest was studied. One recessive gene or linked genes, the same in both smut species, appeared to confer virulence on both cultivars. Earlier investigators had found identical virulence genes in both species of smut for the cultivars Excelsior, Lion, Pannier and Trebi. Therefore, testing for resistance or susceptibility in a breeding program could be done with a strain of only one of the species.

AbstrakKebiasaan masyarakat Indonesia dalam mengkonsumsi teh, memberikan peluang yang besar dalam pengembangan kombucha. Kombucha merupakan minuman yang terbuat dari teh yang difermentasi menggunakan mikroorganisme, yang mempunyai lebih banyak manfaat dibandingkan dengan teh biasa. Aktivitas mikroorganisme selama fermentasi akan menghasilkan berbagai senyawa yang bermanfaat bagi kesehatan, diantaranya adalah terbentuknya senyawa fenolik. Semakin tinggi senyawa fenolik yang dihasilkan maka semakin tinggi pula aktivitas antioksidannya. Selain itu kombucha mengandung senyawa-senyawa organik yang bermanfaat bagi tubuh sehingga sangat berpotensial sebagai pangan fungsional. Makalah ini bertujuan untuk memaparkan peluang kombucha sebagai pangan fungsional, manfaat kombucha, nilai gizi, jenis mikroba yang berperan, proses pembuatan kombucha serta aktivitas antioksidan minuman kombucha dari berbagai komoditas seperti rosela, daun salam, daun jambu, daun sirih, daun sirsak, daun kopi, daun teh, bawang tiwai, teh hijau, teh oolong, daun coklat, daun mangga dan daun tin. Diharapkan minuman kombucha sebagai alternatif diversifikasi pangan fungsional yang dapat bermanfaat bagi kesehatan dan meningkatkan immunomodulator.AbstractThe habits of the Indonesian people in consuming tea, provide a great opportunity in the development of kombucha. Kombucha is a beverage made from fermented tea using microorganisms, which has more benefits compared to original tea. Microorganism activity during fermentation will produce various compounds that are beneficial to health, including the formation of phenolic compounds. The higher the phenolic compound produced, the higher the antioxidant activity. In addition kombucha contains organic compounds that are beneficial to the body so it is very potential as a functional food. This paper aims to explain the opportunities of kombucha as functional food, the benefits of kombucha, nutritional value, the type of microbes that play a role, the process of making kombucha and the antioxidant activity of kombucha drinks from various commodities such as rosella, “salam” leaves, guava leaves, “sirih” leaves, soursop leaves, coffee leaves , tea leaves, onion tiwai, green tea, oolong tea, cocoa leaves, mango leaves and tin leaves. Kombucha drinks are expected as an alternative to functional food diversification that can benefit health and enhance immunomodulators.
