Fructan was precipitated from a water and ethanol extract of oat (Avena sativa L.) and barley (Hordeum vulgare L.). The degree of polymerization and response on a differential refractometer, based on peak area and height, was compared to fructan collected from a lead-based HPLC column and to commercially available inulin. Statistically significant differences are discussed.

Densoviruses (DVs) infect arthropods and belong to the Parvoviridae family. Here, we report the complete coding sequence of a novel DV isolated from the plant Hordeum marinum (Poaceae) by viral metagenomics, and we confirmed reamplification by PCR. Phylogenetic analyses showed that this novel DV is related to the genus Iteradensovirus.

Laboratory experiments were conducted to compare the expression of Diuruphis noxia (Mordvilko) (Homoptera: Aphididae) resistance in four plant introduction (PI) lines of wild barley (Hordeum) infected with different species or strains of endophytic fungi (tribe Balansieae, family Clavicipitaceae, Neotyphodium gen. nov. [formerly Acremonium]). Aphid densities were significantly lower on endophyt...

Spectroelectrochemical studies of the intervalence charge transfer (IVCT) characteristics of both diastereoisomeric forms of the dinuclear complex [{Ru(bpy)2}2(mu-dpi-)]n+ [bpy=2,2'-bipyridine; dpi-=4,5-di(2-pyridyl)imidazolate] showed that the degree of inter-metal electronic coupling (or valence delocalization) is dependent on stereochemical identity. Increasing the relative concentration of ...

ABSTRACT. Barley (Hordeum vulgare L.) is one of the most widely cultivated stable food crops in world. grain samples were collected from four selected areas (Bahir Dar, Bure, Finote Selam and Debre Markos) Ethiopia types processed (kolo, porridge, bread injera) prepared it. The levels essential non-essential metals barley grains its determined by microwave plasma-atomic emission spectrometry af...

barley belongs to the poaceae which is the largest monocotyledon family. plastid single-copy gene acetyl-coa carboxylase (accase) is the first step in the biosynthesis of fatty acids and therefore, it is used to study the phylogenetic relationships, evolutionary and systematic of grasses. in this study, for the first time, phylogenetic relationship of eight species of hordeum genus from iran in...

Agro-hydrological models have increasingly become useful and powerful tools in optimizing water and fertilizer application, and in studying the environmental consequences. Accurate prediction of water dynamics in such models is essential for models to produce reasonable results. In this study, detailed simulations were performed for water dynamics of rainfed winter wheat and barley grown under ...

J. Inst. Brew. 113(2), 147–153, 2007 Fungal hydrophobins have been shown to induce gushing of beer. In order to study the occurrence and fate of hydrophobins at different stages of the production chain of beer, barley samples artificially infected in the field with Fusarium culmorum, F. graminearum and F. poae were collected during the growing period as well as during various stages of the malt...
