Pflanzenphysiologische Untersuchungen der nichtparasitären Blattverbräunung der Sommergerste "Hordeum vulgare" L.
… Blattverbräunung (NBV) bei der Sommergerste Hordeum vulgare L. untersucht. Ziel der Arbeit war es, herauszufinden, durch welche Faktoren die NBV ausgelöst wird. Ausgangspunkt für die Versuche waren Beobachtungen, die zur allgemeinen Hypothese führten, dass es sich bei der NBV um eine …

Genetic analysis of tissue culture responses in barley (Hordeum vulgare L.).
The overall objectives of this thesis were to screen barley genotypes for in vitro culture response; and to use the double haploid (DH) lines derived from the cross between responsive and unresponsive parental lines to confirm the location of previously reported QTL that control barley tissue …

Physiological and molecular mechanisms of salt tolerance in barley (Hordeum vulgare L.)
Two isogenic barley cultivars Golden Promise and Maythorpe were used in this study to investigate physiological and molecular mechanisms of salt tolerance. Using the mRNA differential display technique, 21 cDNA fragments were cloned from young leaves, 10 of them had homologues from GenBank. A …

Evaluation of Barley (Hordeum vulgare L.) Stem and Root Traits that Influence Lodging
Barley (Hordeum vulgare L.) lodging is a detrimental phenomenon that occurs globally and causes several hundred million dollars in financial losses annually to the industry due to reduced yield, downgraded quality, and increased disease load. While lodging can be managed through agronomic …

Genetic diversity of the HvFT1 flowering gene in Nordic spring barley (Hordeum vulgare L.)
… 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 maturing …

IDENTIFICATION AND CHARACTERIZATION OF GENETIC LOCI FOR CULM MORPHOLOGY TRAITS IN BARLEY (HORDEUM VULGARE L.)
Barley (Hordeum vulgare L.) is one of the most important cereal crops worldwide and it has been widely used as a model species in plant genetics and breeding. Stem lodging is a major constraint to yield potential and grain quality in barley. Since the Green Revolution, height reduction has been the …

Assessment of stress-induced and developmentally-induced DNA methylation changes in barley (Hordeum vulgare L.)
DNA methylation is involved in both plant development and adaptation to environmental stress. Changes in DNA methylation can affect the expression of genes that are important for both plant tissue differentiation and stress response. Characterisation of tissue and stress specific methylation …

Regulation of (1,3;1,4)-beta-glucan synthesis in barley (Hordeum vulgare L.) endosperm and leaf tissues.
… for (1,3;1,4)-β-glucan synthesis in barley (Hordeum vulgare L.) in both endosperm and leaf tissues. For the grain (1,3;1,4)-β-glucan content regulation study, transcriptional profiles of candidate genes involved in (1,3;1,4)-β-glucan synthesis and degradation, from the developing barley …

Characterization of Hulled and Hulless Winter Barley, Hordeum vulgare L., Through Traditional Breeding and Molecular Techniques
… of hulled and hulless winter barley (Hordeum vulgare L.) is necessary for improvement using traditional and molecular breeding techniques. Identification of genomic regions conferring resistance to Fusarium head blight (caused by Fusarium graminearum), leaf rust (caused by Puccinia …

Natural genetic variation and gene expression patterns underlying lateral shoot (tiller) development in barley (Hordeum vulgare L)
The main shoot and other above-ground tissues develop from the shoot apical meristem (SAM), including axillary meristems (AXM) from which lateral branches develop. In barley, lateral branches called tillers contribute directly to grain yield and define shoot architecture. Two studies were completed …

Development of intensive nitrogen management strategies for winter barley (Hordeum vulgare L) in the mid-Atlantic region
Winter barley (Hordeum vulgare L.) production in the mid-Atlantic region occupies a substantial amount of arable land. Variable levels of winter and spring precipitation can result in N loss. The objectives of this study were to determine the optimum rate and timing of N fertilization and develop …

Contribution à l'étude de la relation parasitaire entre Typhula incarnata Lasch ex Fr. et l'orge d'hiver (Hordeum vulgare L. var. hybernum VIB.)
Typhula incarnata est une minuscule clavaire psychrophile qui peut être pathogène sur un grand nombre de graminées aux faibles et moyennes latitudes. Dans les décennies 1970 et 1980, ce champignon a connu en Belgique un grand développement dans les cultures d'orge d'hiver où il a souvent été …

Exploring variation in water use efficiency in barley (Hordeum vulgare L.) among wild and circadian mutant varieties, and its impact on responses to drought
Climate change will drive substantial changes in water resources and uses across the world, while population growth, changing dietary preferences and biofuel use will require greater agricultural output. Yet farmland is not likely to increase, therefore yields must rise. Episodes of drought arising …

Earliness factors in Nordic spring barley (Hordeum vulgare L.) Detection of QTL for growth and development traits in a Golf x Tampar barley mapping population
Barley (Hordeum vulgare L.) is the fourth most grown cereal crop in the world and can be successfully grown in a broad range of environments. Success of cultivation in subarctic regions such as Iceland depends largely on the ability of breeders to create high yielding cultivars that are adapted to …
