abstract in order to investigate the effects of different irrigation regimes on yield and yield components of three chickpea cultivars, an experiment was conducted during the 2007 growing season at mashhad. six irrigation regimes including i1= full irrigation, i2= irrigation at branching, i3= irrigation at flowering, i4= irrigation at pod formation, i5= irrigation at seed filling stage, and i6=...

Poor grain filling of inferior grains located on lower secondary panicle branch causes great drop in rice yield and quality. Dynamic gene expression patterns between superior and inferior grains were examined from the view of the whole transcriptome by using RNA-Seq method. In total, 19,442 genes were detected during rice grain development. Genes involved in starch synthesis, grain storage and ...

in order to study planting date impacts and ending season drought stress  on grain yield and  gaining weight  rate  and wheat filling period characteristics in new advanced bread wheat genotypes ,this research  is done by using plan statistical  of spilt plot  in form of complete random blocks basic  plot with 3 replications in both common separated irrigation  and ending season drought  stress...

This study tested the hypothesis that a controlled water deficit during grain filling of wheat (Triticum aestivum) could accelerate grain-filling rate through regulating the key enzymes involved in Suc-to-starch pathway in the grains. Two high lodging-resistant wheat cultivars were field grown. Well-watered and water-deficit (WD) treatments were imposed from 9 DPA until maturity. The WD promote...

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...

Low temperature at stand establishment and high temperature at reproductive stage are involved in reduction of grain yield of spring maize. A field study was therefore conducted to evaluate different physiological strategies for improving performance of spring maize under temperature extremes. Seed priming and foliar spray with 3% moringa leaf extract (MLE) and 100 mg L-1 kinetin solution alone...
