in order to evaluate the relationship between grain yield and agronomic characteristics in bread wheat genotypes in different planting dates under rainfed conditions, a factorial experiment was conducted based on rcbd with four replications at gonbad-e qabus region, iran, during 2012-2014 growing seasons. number of spikes per unit area, grain filling rate, effective grain filling period, number...
In order to evaluation the effects of mycorrhiza, plant growth promoting rhizobacteria and nano zinc oxide foliar application on effective traits at grain filing of triticale under soil salinity condition, a factorial experiment was conducted based on randomized complete block design with three replications in research greenhouse of Faculty of Agriculture Sciences, University of Mohaghegh Ardab...
It has been proposed that delayed leaf senescence can extend grain filling duration and thus increase yields in cereal crops. We found that wheat (Triticum aestivum) NAM RNAi plants with delayed senescence carried out 40% more flag leaf photosynthesis after anthesis than control plants, but had the same rate and duration of starch accumulation during grain filling and the same final grain weigh...
plant photosynthetate partitioning is important in seed yield formation. in this research, in order to study grain filling procedure of chickpea in the presense of drought stress and nitrogen (n) fertilizer on remobilization rate, final grain weight and grain yield were measured. experiment was performed in an split-factorial using randomized complete block design with three replications. droug...
One of the technology options that can help farmers cope with water scarcity at the field level is alternate wetting and drying (AWD). Limited information is available on the varietal responses to nitrogen, AWD, and their interactions. Field experiments were conducted at the International Rice Research Institute (IRRI) farm in 2009 dry season (DS), 2009 wet season (WS), and 2010 DS to determine...
In order to study the effect of sowing date on grain yield and grain-filling duration of triticale cultivars, an experiment was conducted based on strip-plot experiment with four replicates at Ramin Agricultural Research and Educational Center (RAREC) during 2009-10. The sowing date treatments were November, 10th (Aban, 20th) and December, 4th (Azar, 14th) and the cultivars include: ET.79-3،ET....
BACKGROUND AND AIMS Experiments have shown that biotrophic fungi divert assimilates for their growth. However, no attempt has been made either to account for this additional sink or to predict to what extent it competes with both grain filling and plant reserve metabolism for carbon. Fungal sink competitiveness with grains was quantified by a mixed experimental-modelling approach based on winte...
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 ...
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...
