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 ...

in order to investigation of waterlogging stress effects on morphological and physiological traits of rapeseed in different developmental stages, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental...

in order to investigate the effects of different irrigation regimes on yield and growth indices of three chickpea cultivars, an experiment was conducted during the 2007 growing season at mashhad (iran). 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; dry ...

stem reserve remobilization is very important to keep the grain yield in wheat under terminal drought but the importance of this mechanism is unclear under terminal salinity. in this research stem reserve remobilization under terminal salinity were studied in greenhouse on four genotypes no14 and no49, different in remobilization, and bam as salt-tolerant and ghods as salt-sensitive cultivars. ...

It is well established that a high external NH(+) 4 concentration depresses many processes in plant development, but the underlying mechanisms are still not well understood. To determine whether the negative effects of high levels of NH(+) 4 are related to competitive cation uptake, wheat was grown in a field with moderate (18 g N m(-2)) and high (30 g N m(-2)) supplies of NH(+) 4 in the presen...

in order to study the effect of irrigation cut on dry matter remobilization and some of agronomy traits on spring barley, a field experiment was conducted by using a split-plot based on randomized complete block design (rcbd), in three replications, at agricultural and natural resource research center of ardebil, in 2009. irrigation treatments included normal irrigation (as local routine in pas...

Post-anthesis drought affects wheat production worldwide, primarily through the limitation of grain filling. The enhanced remobilization stem reserves induced by can provide considerable carbon sources for aim this study, which was part an ongoing wheat-breeding program targeting tolerance, to assess ability 20 contrasting common genotypes (2 cultivars, 8 F6:7 families (FAM), and 10 parent (PAR...

The experiment was conducted to investigate potential causes of grain sterility in widely cultivated rice variety in Malaysia, MR219 and its two mutant lines (RM311 and RM109) by examining the source-sink relations. RM311 produced increased dry matter yield both at heading and maturity and also showed higher grain yield with greater proportion of grain sterility than the other two genotypes (RM...
