DNA microarrays, being high-density and high-throughput, allow quantitative analyses of thousands of genes and their expression patterns in parallel. In this study, Barley1 GeneChip was used to investigate transcriptome changes associated with boron (B) toxicity in a sensitive barley cultivar (Hordeum vulgare L. cv. Hamidiye). Eight-day-old aseptically grown seedlings were subjected to 5 or 10 ...

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...

in order to study the complementary effects of application time of two herbicides sulfosulfuron 75% wg (apyrus) and 75% sulfosulfuron + 5% metsulfuron-methyl (total) and planting wheat density on wild barley (hordeum spontaneum koch.) control, an experiment was conducted in randomized complete blocks design with two-factors during 2012-2013 growing season in zarghan (fars). the first factor was...

The aim of this study was to evaluate gastrointestinal microbial population response and performance of broiler chickens fed organic acids and silver nanoparticles coated on zeolite under heat stress condition. In this experiment, 375 one-day old broiler chicks (Cobb 500) were randomly divided into 5 treatments containing 5 replicates with 15 birds in each replicate. Five dietary treatments wer...

Ingestion of high levels of rapidly fermented carbohydrates after parturition often leads to the production of excessive quantities of organic acids that may exceed the buffering capacity of the rumen and cause pH to drop. Ruminal acidosis results in animal discomfort, anorexia, depression, decreased digestibility, and decreased milk production. In the present study, we examined the effects of ...

sewage sludge with having the organic matter is considered as a source of micro and macro elements. in order to investigate the effect of different levels and period of application of sewage sludge (ss) on organic matter, respiration, and acid and alkaline phosphatase activity, factorial design were studied, in 3 replications. sewage sludge at five levels, (20 and 40 tons of sewage sludge, 20 a...

Cinmethylin, a pre-emergent applied active ingredient, inhibits the fatty acid thioesterase and offers new option in chemical control of Alopecurus myosuroides, one most problematic weeds arable farming Europe. It was assumed that with delayed sowing winter wheat barley due to more humid cooler conditions, efficacy cinmethylin against A. myosuroides increases. Four field trials were conducted S...

background: foot -and- mouth disease (fmd) is endemic in iran. molecular techniques for diagnosis of persistent infection or carrier animals have shown a potential ability to improve the detection of a low genome copy number in samples. objectives: the purpose of this study is to evaluate the frequency of foot and mouth disease viral carriers in slaughtered sheep in mashhad industrial abattoir ...
