Amylose and amylopectin are the 2 major components of plant storage starch. The rice starch branching enzyme (RBE) plays an important role in the starch components of rice. In the present study, we selected a specific 195-bp segment from the RBE3 gene to construct hairpin DNA, which was driven by an endosperm-specific high molecular weight glutenin promoter to regulate the biosynthesis of starc...

in order to investigate effective morpho-physiological traits related to salinity resistance, and their relationship with grain yield as well as study of salinity tolerance and susceptibility indices in 169 barley recombinant inbred lines, a  population of barley derived from a cross between arigashar and igri, this experiments were carried out using alpha lattice design with two replications d...

to evaluate canola cultivars response to physiological characteristics and grain yield end seasonal drought stress in weather condition of ahvaz, farm experiments were done at research farm of khuzestan agriculture and natural resources center. during 2007-2008 and 2008-2009 crop years. farm test comprised drought stress was done as split plot form with randomize complete block design with four...

The objective of the study was to determine geometric, gravimetric, aerodynamic, and frictional properties maize grain as affected by varietal differences moisture content. Honampa, Omankwa, Abontem, Timtim, Obatanpa were five varieties studied. Moisture content, geometric properties, gravimetric aerodynamic mean diameters ranged between 6.65 7.55 mm, while projected areas 52.98 73.12 m2. surfa...

to investigate the yield and agronomic traits of winter bread wheat genotypes in irrigating condition and also to determine the relationship of these traits with grain yield, 15 advanced genotypes of wheat along with three conventional cultivars where studied using randomized complete block design in three replications in 2010 growing season at kheyr-abad agricultural research station. the anal...

Two durum wheat trials were carried out in Mediterranean conditions during 2010/2011 and 2011/2012 growing seasons at Plant Breeding Station-Elvas (Portugal). The experiments were conducted under rainfed conditions however, in 2012, due to extreme drought it was necessary to use artificial irrigation between booting and mid grain filling stage. Thirty durum wheat genotypes were studied and six ...

The aim of the study was to compare two ozone exposure patterns with different peak concentrations under equal dose conditions. Spring wheat (Triticum aestivum cv. ‘Nandu’) was ‘pre-cultivated’ under glasshouse conditions and exposed to two different ozone exposure scenarios (A: 1700–0900 h: 20 ppb, 0900–1700 h: 65 ppb; B: 1600–1200 h: 20 ppb, 1200–1600 h: 110 ppb) in large fumigation chambers ...

Increasing grain yield potential in wheat has been a major target of most breeding programs. Genetic advance has been frequently hindered by negative correlations among yield components that have been often observed in segregant populations and germplasm collections. A tetraploid wheat collection was evaluated in seven environments and genotyped with a 90K SNP assay to identify major and stable...
