Wheat and Barley

چکیده
Moisture adsorption rates for stored grains are important for accurate modeling of drying and storage. Wheat and barley samples at initial moisture contents typical of grain storage were exposed to several levels of higher humidity at two temperatures to measure adsorption rates. The best fit to the data was achieved with the Page equation and the cellular diffusion equations. The adsorption rates were lower than those of comparable desorption tests. The adsorption rates for barley were lower than for wheat due to lower diffusion coefficients for the barley endosperm and germ as compared to wheat.

متن کاملPhytotoxicity effects of soil amended residues of wild barley (Hordeum spontaneum Koch) on growth and yield of wheat (Triticum aestivum L.)
Wheat (Triticum aestivum) growth and yield are depressed by physical and chemical interference of weeds. Recently, wild barley (Hordeum spontaneum) population has increased in wheat fields of many provinces of Iran. Since, little is known about the allelopathic effects of wild barley residues in soil, greenhouse studies were conducted to examine the effects of soil amended residues of wild barl...
متن کاملGrowth Response of Winter Wheat (Triticum aestivum L.) and Wild Barley (Hordeum spontaneum Koch) to Nitrogen
A greenhouse study was conducted to investigate the effects of nitrogen (N) on wild barley (Hordeum spontaneum Koch) interference with winter wheat (Triticum aestivum var. Pishtaz) by an additive series experiment. The experiment was conducted in a split plot design with 3 replications. Wheat plant height losses were on average 30, 10, and 10% in a wild barley density of 16 plants per pot with ...
متن کاملBarley allele-specific amplicons useful for identifying wheat-barley recombinant chromosomes.
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...
متن کاملINHIBITORY EFFECTS OF WILD BARLEY (HORDEUM SPONTANEUM Koch.) RESIDUES ON GERMINATION AND SEEDLING GROWTH OF WHEAT (TRITICUM AESTIVUM L.) AND ITS OWN PLANT
Laboratory studies were conducted to examine the effects of different concentrations of wild barley (Hordeum spontaneum Koch.) shoot and seed extracts on germination and seedling growth of wheat (Triticum aestivum L.) and wild barley. In this study, all wild barley shoot extract concentrations (with exception of lowest concentration) significantly reduced wheat seed germination after 7 days. Sh...
متن کاملA Welfare Analysis of Wheat Self-Sufficiency Policy and the Influence on the Barley Market in Iran: A Game Theory Approach
ABSTRACT- Iran achieved its self-sufficiency goal in wheat production a few years ago, perhaps at the expense of decreasing the production of other grains specially barley as stated by critics in the country. Considering the dependency of wheat and barley markets on each other, policy preference functions were estimated separately for each market. Incorporating political weights, a game theory ...
