Seed dormancy has fundamental importance in plant survival and crop production; however, the mechanisms regulating dormancy remain unclear [1-3]. Seed dormancy levels generally decrease during domestication to ensure that crops successfully germinate in the field. However, reduction of seed dormancy can cause devastating losses in cereals like wheat (Triticum aestivum L.) and barley (Hordeum vu...

The subcellular compartmentation of nucleoside diphosphate kinase (EC 2.7.4.6) and the uridine nucleotides has been studied in leaves. Membrane filtration of barley (Hordeum vulgare L.) leaf mesophyll protoplasts and differential centrifugation of spinach (Spinacia oleracea L.) leaf extracts showed that about half the nucleoside diphosphate kinase is present in the cytosol. The activity is adeq...

INTRODUCTION Salinity and waterlogging are two major abiotic stresses severely limiting barley production. The lack of a reliable screening method makes it very hard to improve the tolerance through breeding programs. METHODS This work used 188 DH lines from a cross between a Chinese landrace variety, TX9425 (waterlogging and salinity tolerant), and a Japanese malting barley, Naso Nijo (water...

to study the mixing rates effects of barley (hordeum vulgare l.) and chickpea (desi type) (cicer ariethinum l.) on forage production under dryland conditions, a field experiment was conducted at agricultural research station of university of tehran (karaj campus) during the 2003 – 2004 growing season. the 11 treatments of this experiment were statistically compared based on a randomized complet...

The Russian wheat aphid, Diuraphis noxia (Mordvilko) (Hemiptera: Aphididae), causes severe damage to barley, Hordeum vulgare L. (Poales: Poaceae), in the highlands of Ethiopia. Little information is available on the control of this pest in Ethiopia. An experiment aimed at evaluating the resistance of barley varieties from the USA to D. noxia populations and determining biotypic variation betwee...

The requirements for modelling photosynthesis and related processes within the framework of a Functional-Structural Plant Model (FSPM; cf. Vos et al. this volume) are discussed. A combined local gas (carbon dioxide, water vapour) and radiant energy exchange model (GREM) is presented, that was specified to be embedded into an FSPM. The model accounts for the effect of organ nitrogen content (N) ...

Photoperiodic flowering is a major factor determining crop performance and is controlled by interactions between environmental signals and the circadian clock. We proposed Hvlux1, an ortholog of the Arabidopsis circadian gene LUX ARRHYTHMO, as a candidate underlying the early maturity 10 (eam10) locus in barley (Hordeum vulgare L.). The link between eam10 and Hvlux1 was discovered using high-th...

The stability of aging barley calli was investigated with the barley retroelement 1 (BARE-1) retrotransposon specific inter-retrotransposon amplified polymorphism (IRAP) technique. Mature embryos of barley (Hordeum vulgare cv. Zafer-160) were cultured on callus induction MS medium supplemented with 3 mg/L 2,4-D and maintained on the same medium for 60 days. Ten IRAP primers were used in 25 diff...

Zuo Z.Y., Li X.N., Xu C., Yang J.J., Zhu X.C., Liu S.Q., Song F.B., Liu F.L., Mao H.P. (2017): Responses of barley Albina and Xantha mutants deficient in magnesium chelatase to soil salinity. Plant Soil Environ., 63: 348–354. Soil salinity reduces the plant growth and grain yield in barley. The barley mutants Albina and Xantha, deficient in magnesium chelatase, represent a suitable model object...
