wheat stem reserves can be an important contributor to grain filling particularly under drought conditions. knowledge concerning genetic variation in stem reserve could be empolyed to develop wheat genotypes more adapted to harsh environments. the aim of this research was to study the ability to store assimilates in stem and their re-mobilization to the grain in all the 81 iranian wheat cultiva...

to assess moisture stress tolerance at the reproductive growth stage in 11 promising genotypes of spring rapeseed (brassica napus l.), two field experiments were conducted in two growing seasons (2008-2010) at the agricultural research center of safiabad, dezful, iran. genotypes were sown under two non-stress (well-irrigated) and moisture stress (irrigation ceased at flowering) conditions using...

it is suggested that cultivars of wheat (triticum aestivum l.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. water use efficiency (wue) is worthy of exploration in this regard. in this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg nha-1) and a plant growth retardant (ch...

Drought is a major environmental constraint to crop distribution and productivity. Stem water-soluble carbohydrates (WSC) buffer wheat grain yield against conditions unfavorable for photosynthesis during the grain filling stage. In this study, 262 winter wheat accessions and 209 genome-wide SSR markers were collected and used to undertake association analysis based on a mixed linear model (MLM)...

the effect of seed inoculation by phosphate solubilizing microorganisms on growth, yield and nutrient uptake of maize (zea mays l. sc. 704) was studied in a field experiment. this experiment was conducted in meshkin abad experimental station during 2005. the experiment design consisted of four randomized complete blocks in a split-factorial arrangement. the main-plots regarding simulating water...

Droughtis oneof the most importantfactors limitingcrop productioninarid and semiaridregions, such as Iran.In order to study drought stress in four grain sorghum varieties (Kimia, Sepideh, KGS15 and KGS23), an experiment was laid in randomized complete block design with three replications in a split plot arrangement. Water treatments were considered the main plot at three levels: irrigation afte...

To determine root growth and grain yield of winter wheat (Triticum aestivum L) under moderate drought stress, a nursery experiment and a field trial were conducted with or without water stress using three representative cultivars released in different years: CW134 (old landrace), CH58 (modern cultivar) and CH1 (new release). In the nursery experiment, plants were grown in soil-filled rhizoboxes...
