J. Pritchard | 1996The aim of the present study was to quantify osmotic pressures directly in the translocation pathway, from leaf to growing root tip, in order to understand the forces driving solutes from a source to a sink. Solutes move through the translocatio[...]

H. Cabrera ; V. Argandona ; G. Zuniga ; L. Corcuera | 1995To compare the effects of aphid infestation with some effects of wounding and drought-stress, several physiological parameters and metabolite concentrations were measured in infested, mechanically wounded or water-stressed young barley plants (H[...]

J. Webster ; D. Porter ; J. Burd ; D. Mornhinweg | 1996The Russian wheat aphid, Diuraphis noxia (Mordvilko), is a serious pest of barley in western North America. To help manage this pest, a Russian wheat aphid-resistant germplasm line STARS-9301 B was recently released to barley breeders for incorp[...]

D. Hays ; D. Porter ; J. Webster ; B. Carver | 1999The feeding behavior of virulent and avirulent greenbug biotypes after preconditioning of the plant with virulent and avirulent greenbug biotypes was examined. A pair of near-isolines of barley, Hordeum vulgare L., differing by the antibiosis gr[...]

J. Velozo ; R. Alvarez ; G. Wachter ; B. Timmermann ; L. Corcuera | 1999The kinetics of accumulation of gramine were measured in three aphid infested and non-infested cultivars of barley (Hordeum vulgare; cvs. Frontera, Libra and Acuario). After 6 days of infestation gramine content increased 10-fold in the cvs. Lib[...]

S. Moharramipour ; H. Tsumuki ; K. Sato ; H. Yoshida | 1997A set of 150 doubled-haploid (DH) barley (Hordeum vulgare L.) lines derived from the cross of Harrington/TR306 was used to determine the number and chromosomal location of quantitative trait loci (QTLs) controlling resistance to cereal aphids. T[...]

We investigated the phloem loading pathway in barley, by determining plasmodes-matal frequencies at the electron microscope level for both intermediate and small blade bundles of mature barley leaves. Lucifer yellow was injected intercellularly [...]

P. Minchin ; M. Thorpe ; J. Farrar ; O. Koroleva | 2002Phloem loading of carbohydrate within a mature exporting leaf of a barley seedling is shown to respond quickly to a change in the temperature of the root and the shoot meristem. This is interpreted as a close coupling between source supply and s[...]

J. Weibull | 1994The phloem sap content of glutamic acid was determined in EDTA leaf exudate samples from a collection of Hordeum vulgare subsp. spontaneum previously screened for Rhopalosiphum padi resistance. Segregating populations of crosses between subsp. s[...]

X. Ni ; S. Quisenberry ; B. Siegfried ; K. Lee | 1998The effect of cereal leaf surface wax on Diuraphis nox-ia (Mordvilko), the Russian wheat aphid, probing behavior epicuticular wax from wheat (Triticum aestivum L.) c.v. 'Arapahoe' and 'Halt' was different from barley (Hordeum vulgare L.) c.v. 'M[...]
