Drought stress is one of the limiting factors for grain filling and yield in wheat. The determinants individual weight depend on current assimilation extent remobilization culm reserves to grains. A pot experiment was conducted with eight wheat cultivars at Pot House study contributions culm, including sheath under drought stress. enforced by restricting irrigation during grain-filling period. ...
This study tested the hypothesis that the interaction between polyamines and ethylene may mediate the effects of soil drying on grain filling of rice (Oryza sativa L.). Two rice cultivars were pot grown. Three treatments, well-watered, moderate soil drying (MD), and severe soil drying (SD), were imposed from 8 d post-anthesis until maturity. The endosperm cell division rate, grain-filling rate,...
Identification of easily measured physiological traits contributing to yield under specified environmental conditions would benefit genotypic selection for grain sorghum. A field experiment was conducted to determine broad-sense heritability and expected genetic advance, and to examine the relationships of grain yield with 11 physiological traits related to developmental periods, vegetative gro...
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 of nitrogen fertilizer application and seed inoculation by azotobacter and azosprillium on yield, rate and grain filling period of corn sc-500 cultivar, a factorial experiment was conducted based on randomized complete block design with three replications in farm of agriculture and natural resource research center of azarbaijan-e- shargi province in 2011. the factors were...
In an investigation of the role of peroxidase enzymes in the differentiation of the tissues of the crease region of barley, plants of winter barley cv. Halcyon were grown from anthesis onwards in controlled conditions at a constant temperature of 16 degrees C. Four ears were harvested at 2-d intervals from 6 d after anthesis (daa) until 50 daa. Grains from mid-ear were used for (i) fresh and dr...
In bread wheat, QTL interval mapping was conducted for nine important drought responsive agronomic traits. For this purpose, a doubled haploid (DH) mapping population derived from Kukri/Excalibur was grown over three years at four separate locations in India, both under irrigated and rain-fed environments. Single locus analysis using composite interval mapping (CIM) allowed detection of 98 QTL,...
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...
The response of wheat crops to elevated CO2 (eCO2 ) was measured and modelled with the Australian Grains Free-Air CO2 Enrichment experiment, located at Horsham, Australia. Treatments included CO2 by water, N and temperature. The location represents a semi-arid environment with a seasonal VPD of around 0.5 kPa. Over 3 years, the observed mean biomass at anthesis and grain yield ranged from 4200 ...
