The Tibetan hulless barley (Hordeum vulgare L. var. nudum), also called "Qingke" in Chinese and "Ne" in Tibetan, is the staple food for Tibetans and an important livestock feed in the Tibetan Plateau. The diploid nature and adaptation to diverse environments of the highland give it unique resources for genetic research and crop improvement. Here we produced a 3.89-Gb draft assembly of Tibetan h...
Barley consumption is limited in broiler chicken diet due to their β. glucanas polysaccharide content. The application of synthetic enzymes in poultry diet can increase the barley content. The purpose of this experiment is to study the effect of enzyme supplement-β-glucanas on the performance of broiler chickens, percentage of abdominal fat, intestine weight and economic evaluation of productio...
Barley is an important crop for the production of malt and beer. However, crops such as rice and wheat are rarely used for malting. α-amylase is the key enzyme that degrades starch during malting. In this study, we compared the genomic properties, gene copies, and conserved promoter motifs of α-amylase genes in barley, rice, and wheat. In all three crops, α-amylase consists of four subfamilies ...
Strips of fallow vegetation along cropland borders are an effective strategy for providing brood habitat for declining populations of upland game birds (Order: Galliformes), including northern bobwhite (Colinus virginianus), but fallow borders lack nectar-producing vegetation needed to sustain many beneficial insect populations (e.g., crop pest predators, parasitoids, and pollinator species). P...
Preventing the introduction of weeds into the farming system through sowing of clean seeds is an essential component of weed management. The weed seed contamination of cleaned grain and herbicide resistance levels of the recovered weed seeds were examined in a study conducted across 74 farms in the Western Australian grainbelt. Most farmers grew and conserved their own crop seed. The majority o...
Miscanthus is a C4 herbaceous perennial species and it was chosen as bioenergy crop due to high biomass yield. sinensis has many phenotypes which are adaptated various environments in China. In this study, 421 accessions of M. were collected from 22 provinces, the genetic polymorphisms amongst these germplasm collections identified using 20 primer pairs designed against 10 each eSSR gSSR transf...
in this research, the citations received by doaj’s journals from the isi web of science’s articles in 2003 to 2008 were studied and compared. the citations received by the journals in five fields (arts & humanities, social sciences, pure sciences, technology & engineering, and health & medical sciences) as well as the difference among the citations received by doaj’s journals in the above- ment...
Eighty-one cultivars from 12 field crop species were assessed for suitability as hosts to the root lesion nematode, Pratylenchus neglectus, in two field trials. Host status was assessed on the basis of either final P. neglectus densities in soil or multiplication rate under different crops. Both techniques gave consistent results for crop and cultivar ranking, and it was therefore concluded tha...
in order to investigate the yield and quality of forage in intercropping barley and fennel, an experiment was carried out as split plot based on a randomized complete block design with three replications at the research farm of agriculture and natural resources of ramin university during growing season of 2012-2013. four treatments levels of nitrogen including: (0, 70, 140 and 210 kgn.ha-1) hav...
sunn pest (eurygaster integriceps put.) cause serious economic damage to wheat and barley in borujerd, north of lorestan province, iran. sweep net sampling, is the most convenient sampling procedure for many arthropods, but it is difficult to interpret in terms of accuracy and precision. much of the variation of sweep net catches, stems from human factors and its calibration. in this research, ...
