Barley straw serves as livestock feed and mulch for soil water conservation in the mixed barley-livestock systems of Ethiopian highlands. High demand barley biomass system creates competition between two uses. This study aimed to identify determinants utilization feed. Data on production use were collected from 236 households using a structured questionnaire. Use purposes at three levels, 0–15%...

The barley leaf rust fungus forms appressoria over host leaf stomata and penetrates via the stomatal pore. High levels of avoidance to leaf rust fungi have been described in some wild accessions of Hordeum species where a prominent wax layer on the stomata inhibits triggering of fungal appressorium differentiation. Leaf rust avoidance has not yet been found in H. vulgare. Since cuticular leaf w...

Chloroplast DNA (cpDNA) diversity was found within and among populations (245 accessions total) of wild barley, Hordeum vulgare L. ssp. spontaneum Koch from Israel and Iran. Three polymorphic restriction sites (HindIII, EcoRI, BclI) which define three distinct cpDNA lineages were detected. One lineage is common to populations in the Hule Valley and Kinneret of northern Israel, and in Iran. The ...

Barley HvPIP2;1 is a plasma membrane aquaporin and its expression was down-regulated after salt stress in barley [Katsuhara et al. (2002) Plant Cell Physiol. 43: 885]. We produced and analyzed transgenic rice plants over-expressing barley HvPIP2;1 in the present study. Over-expression of HvPIP2;1 increased (1) radial hydraulic conductivity of roots (Lp(r)) to 140%, and (2) the mass ratio of sho...

agricultural mechanization project must be identified in a short time frame to do a certain way; otherwise, cost is not the time to come and will also result in reduced yield. to avoid these costs in farming systems is necessary in any region that agricultural mechanization projects are and scheduling and planning as well as scientific until activities included in the project to fruition are do...

background and objectivesintercropping or simultaneous growing of two or more crops on the same piece of land has the potential of enhanced ecosystem productivity. in a cereal-legume intercropping system, an increase in cereal and a decrease in legume intercrop yield is reported. several indices such as land equivalent ratio (ler), relative crowding coefficient (k), competitive ratio (cr), aggr...

This paper discusses archaeobotanical remains of naked barley recovered from the Okhotsk cultural layers of the Hamanaka 2 archaeological site on Rebun Island, northern Japan. Calibrated ages (68% confidence interval) of the directly dated barley remains suggest that the crop was used at the site ca. 440-890 cal yr AD. Together with the finds from the Oumu site (north-eastern Hokkaido Island), ...

Barley (Hordeum vulgare cv Prior) leaves converted l-U-(14)C-arginine to labeled proline. Accumulation of radioactivity in proline was greater in wilted leaves, but only after 9 hours of incubation. As the increase in free proline was detectable after only 3 to 6 hours, it is likely that the observed stimulation of proline labeling represents a result rather than a cause of proline accumulation...

Barley (Hordeum vulgare L.) is potentially a new source of genes for wheat (Triticum aestivum L.) improvement. Wheat-barley chromosome recombinant lines provide a means for introgressing barley genes to wheat genome by chromosome engineering, and since these are expected to occur only rarely in special cytogenetic stocks, an efficient selection skill is necessary to identify them. To convert RF...
