Drought is the major abiotic stress that decreases plant water status, inhibits photosynthesis, induces oxidative stress, restricts growth and finally lead to the reduction of wheat yield. It has been proven that drought priming during vegetative growth stage could enhance tolerance to drought stress at grain filling in wheat. However, whether drought priming imposed at grain filling in parenta...

in order to study the effect of irrigation on fatty acid composition, oil and protein content of sunflower cultivars included azargol, allstar, alison and euroflor, an experiment was conducted at experimental field of the agricultural faculty of bu-ali sina university in 2007. treatments were arranged on split plot based on randomized complete block with three replications. the irrigation treat...

Individual grain weight is a major yield component in wheat. To provide a comprehensive understanding of grain weight determination, the carpel size at anthesis, grain dry matter accumulation, grain water uptake and loss, grain morphological expansion, and final grain weight at different positions within spikelets were investigated in a recombinant inbred line mapping population of bread wheat ...

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 ...

Not enough attention has been paid to the comparison in yield performance and N responsiveness between hybrid rice inbred using large number of new cultivars released after 2000 under machine transplanting. Field experiments were conducted 2017 2018; 48 widely planted included four groups, namely indica hybrids (IHs), japonica inbreds (JIs), indica-japonica (IJHs), (IIs) that transplanted by wi...

The grain filling rate (GFR) is an important dynamic trait that determines the final grain yield and is controlled by a network of genes and environment factors. To determine the genetic basis of the GFR, a conditional quantitative trait locus (QTL) analysis method was conducted using time-related phenotypic values of the GFR collected from a set of 243 immortalized F(2) (IF(2)) population, whi...

to identify and characterize bread wheat (triticum aestivum l.) genotypes adapted to terminal water deficit conditions, 51 superior hexaploid wheat genotypes together with commercial check cultivars were studied, in a two stages screening practice, for drought tolerance in karaj, kermanshah, isfahan, neishabour and varamin filed stations under terminal water deficit conditions in 2002-2005 grow...
