Salinity, which is more common in semi-arid and arid areas, increasing every day with climate change, poor quality irrigation water, soil structure. High salt concentration restricts plant production causes productivity loss agriculture. To sustain agriculture saline soils, the determination of species resistant to salinity comes into prominence areas problems. For this reason, research was per...

Germination cues reflect the conditions under which a species is likely to succeed in recruitment. Therefore, knowledge of the seed germination characteristics of key plant species in desertified areas is essential for restoration. The aims of this study were to evaluate the seed germination responses of seven native species, and to explore the implications for vegetation restoration. Seeds of ...

The seasonal change and host preference of arbuscular mycorrhizal (AM) colonization and community composition of five common plant species Agropyron cristatum, Anemarrhena asphodeloides, Cleistogenes squarrosa, Leymus chinensis, and Stipa grandis in the Inner Mongolia steppe were investigated. The AM root length colonization rates were different among the five plant species and were generally h...

The biotypic diversity of the Russian wheat aphid, Diuraphis noxia (Kurdjumov) (Hemiptera: Aphididae), was assessed in five isolates collected in Colorado. Three isolates, RWA 1, RWA 2, and an isolate from Montezuma County, CO, designated RWA 6, were originally collected from cultivated wheat, Triticum aestivum L., and obtained from established colonies at Colorado State University. The fourth ...

A Barcé-halom Dévaványa külterületén, a településtől nyugatra található. 1970-ben régészeti feltárás igazolta kurgán késő rézkori–kora bronzkori eredetét, dokumentált temetkezés Jamnaja-kultúrához köthető. római korban környékét szarmaták lakták. halomfelszínt 18. század vége óta szántóföldként hasznosították. Az 1930-as években keleti oldalából nagymennyiségű földet hordtak el, roncsolás nyoma...

Integrating use of seeded perennial cool-season grass pastures with native rangeland can increase available forage and provide a high plane of nutrition for grazing livestock. Our objective was to compare performance of yearling beef heifers grazing native rangeland with those grazing an integrated system that included seeded forages. Twice-replicated, 3-ha pastures seeded to either ‘Rosana’ we...

The level and pattern of nucleotide variation in duplicate gene provide important information on the evolutionary history of polyploids and divergent process between homoeologous loci within lineages. Kengyilia is a group of allohexaploid species with the StYP genomic constitutions in the wheat tribe. To investigate the evolutionary dynamics of the Pgk1 gene in Kengyilia and its diploid relativ...
