studies on manipulating the source-sink relationships during postanthesis in wheat have shown inconsistent results, concluding that wheat yield could be either sink- or source-limited. most studies have reported data of grain mass as an average of all grains preventing the recognition of different sensitivities to the availability of assimilates of grains placed at different positions within th...

to evaluate interaction of salinity stress and nitrogen use methods on yield and yield components, in experiment was conducted in split plot in randomized complete block with 3 replications. treatments included: salinity of irrigation water levels 1.5, 4.4 and 7.9 ds/m as main plots, and nitrogen treatments 1. using n fertilizer at 3 stage in soil, 2. using two third n fertilizer in soil at pla...

in order to examination of dual purpose herbicides on some wheat physiological indexes in different stages of phenology of this corp, an experiment was conducted in 1386-1387, in kordkoy, golestan province with dry farming condition. this study was performed as factorial in randomized complete block design with 2 factors and 4 replications. the first factor included the type of herbicides: shov...

The primary aim of this research was to study visual spatial attention and its impact on the accuracy diagonal spike in volleyball. A total 20 volleyball players Baghdad participated study. sample homogeneous terms height, weight age players. tests used present were: 1) Visual Spatial Attention Test. 2) Volleyball Spike Based findings study, researcher concluded that has a significant

this study was conducted to evaluate the effect of drought stress on 22 durum wheat genotypes. different characteristics such as grain weight per spike, plant biomass, 100 grain weight, free proline content in leaves, and percentage of cell membrane damage were studied in greenhouse and laboratory conditions. genotypes were sown under normal irrigation and moisture stress conditions. in stress ...

in order to study the sink-source physiological relationship, current photosynthesis, contribution and remobilization of assimilates to grain yield in wheat and triticale genotypes, a field experiment was conducted in iran, ahvaz area on 2003-4. treatments were two bread wheat (simareh and tawer), one durum wheat (showa) and two triticale (juvanillo92 and line 45) genotypes. grain weight change...

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, ...
