the effect of levels of nitrogen on growth and nitrogen uptake patterns and grain protein quality of grain sorghum was investigated by two experiments which were conducted at pakdasht-tehran in 2003. in a completely randomized design with three replications, grain sorghum (sorghum bicolor (l.) moench) hybrid h-726 was grown under greenhouse conditions using water culture technique. the first ex...

Abstract This research was conducted in Toroq Experimental field station, Mashhad, Iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. Moisture stress treatments (at seven levels) were assigned to main plots, including: D1 ( full irrigation), D2 (no irrigation from one-leaf to double ridge) st...

The wheat gluten proteins correspond to the major storage proteins that are deposited in the starchy endosperm cells of the developing grain. These form a continuous proteinaceous matrix in the cells of the mature dry grain and are brought together to form a continuous viscoelastic network when flour is mixed with water to form dough. These viscoelastic properties underpin the utilization of wh...

The influence of grain hardness, determined by using molecular markers and physical methods (near-infrared (NIR) technique and particle size index-PSI) on dough characteristics, which in turn were determined with the use of a farinograph and reomixer, as well as bread-making properties were studied. The material covered 24 winter wheat genotypes differing in grain hardness. The field experiment...

sheath blight disease, caused by rhizoctonia solani ag-1 ia, is one of the most serious fungal diseases of rice, worldwide. rice resistance is a relative phenomenon and disease response varied (due to complex quantitative inheritance and high environmental diversity), so an accurate disease assessment would be difficult. to detect a reliable reaction of rice in a high level of disease developme...

Sorghum is one of the most promising bioenergy crops. Stem juice yield, together with stem sugar concentration, determines sugar yield in sweet sorghum. Bulked segregant analysis (BSA) is a gene mapping technique for identifying genomic regions containing genetic loci affecting a trait of interest that when combined with deep sequencing could effectively accelerate the gene mapping process. In ...

Cereal Chem. 66(3):224-227 A reconstituted whole wheat bread (containing 16.3% bran plus 12.7% was included in the baking process. Addition of a high level of enzymeshorts) with a loaf volume equal to the control was obtained by allowing active soy flour eliminated the need for the no-yeast sponge stage. Certain indigenous lipoxygenase (soaking the nonflour milling fractions) or added salts and...

A field experiment was conducted to evaluate the crop water stress index (CWSI), grain yield and canopy temperature of triticale under two irrigation regimes at Research Station of College of Agriculture and Natural Resources of Darab, Shiraz University, in 2013. A split plot design was used with three triticale cultivars (Sanabad, ET-83-3, and ET-84-5), as sub-plots and four levels of irrigati...

Storage proteins account for about 50% of the total protein in mature cereal grains and have important impacts on their nutritional quality for humans and livestock and on their functional properties in food processing. Current knowledge of the structures and properties of the prolamin and globulin storage proteins of cereals and their mechanisms of synthesis, trafficking and deposition in the ...
