The non-leaf photosynthetic organs have recently attracted much attention for the breeding and screening of varieties of cereal crops to achieve a high grain yield. However, the glume photosynthetic characteristics and responses to high temperature at the late stages of grain filling are not well known in winter wheat (Triticum aestivum L.). In the present study, an experiment was conducted to ...

in order to study the effects of a superabsorbent polymer on yield and yield components of dry land wheat cultivars, a field experiment was carried out in factorial arrangement using randomized complete block design with four replications on research field in khomein city, during 2010-2011 cropping season. the experimental factors included three dry land cultivars called azar2, sardari, rasad a...

To identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. The measured characters consisted of peduncle weight, ...

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...

The results indicated that the seed yield per plant showed a significant positive correlation with most of traits like days to 50% flowering, height, filled grains panicle, number spikelet fertility, flag leaf width, numbers tillers plant, effective panicle length and 100 weight, representing importance these for development great yielding varieties in contrast trait sterility has been reported...

studies manipulating the source-sink relationships during post anthesis in wheat have shown inconsistent results, concluding that wheat yield could be either sinkor source-limited. the aim of this study was to determine source limitation degree of 36 iranian wheat cultivars andto investigate their intrinsic compensatory mechanism in response to source size reduction. a split plot design based o...
