drought is one of the most important factors limiting crop yields around the world. drought stress in plants, the change (increase or decrease) in the production of plant proteins. this research was carried out using bread wheat genotypes. for evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....

Structural characteristics and baking conditions influence the metabolic responses to carbohydrate-containing foods. We hypothesized that consumption of whole wheat or sourdough breads would have a favourable effect on biomarkers of glucose homeostasis after first and second meals, compared with those for white bread. Ten overweight volunteers consumed 50 g available carbohydrate of each of the...

The following method was used to apply the topology of current study evapotranspiration ETo, net irrigation demand, schedules, and total effective rain fall different crop models: using Food Agriculture Organization's (FAO) CROPWAT 8.0 standard software CLIMWAT 2.0 tool FAO-56 Penman-Monteith approach examine variable ETo. Due high temperatures in summer with an annual mean 6.33 mm/day, topolog...

Four experimental diets were formulated to contain 700 g/kg cereal with decreasing levels of wheat:barley inclusion. Diet 1 contained 700 g/kg wheat, diet 2 contained 600 g/kg wheat and 100 g/kg barley, diet 3 contained 500 g/kg wheat and 200 g/kg barley and diet 4 contained 400 g/kg wheat and 300 g/kg barley. The diets were offered to pigs on three trials to investigate effects on the performa...

Leaf growth in monocot crops such as wheat and barley largely follows the daily temperature course, particularly under cold but humid springtime field conditions. Knowledge of the temperature response of leaf extension, particularly variations close to the thermal limit of growth, helps define physiological growth constraints and breeding-related genotypic differences among cultivars. Here, we ...

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...

Orthologous regions in barley, rice, sorghum, and wheat were studied by bacterial artificial chromosome sequence analysis. General microcolinearity was observed for the four shared genes in this region. However, three genic rearrangements were observed. First, the rice region contains a cluster of 48 predicted small nucleolar RNA genes, but the comparable region from sorghum contains no homolog...

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...
