drought is one of the most important factors limiting crop yields around the world. drought stress in plants, the change (increase or decrease) in the production of plant proteins. this research was carried out using bread wheat genotypes. for evaluation of leaf protein pattern in wheat, 10 genotypes were assayed with 3 replications under irrigated (non-stress) and rain-fed (stress) conditions....

to determine chromosomal localization and relationship between field and laboratory indicators of drought tolerance, an experiment was conducted in 2003-2004 cropping season at sararood agricultural research station, kermanshah, iran. seven genotypes of wheat-barley disomic addition lines provided by international center for agricultural research in dryland areas (icarda), their donor and recip...

Two greenhouse experiments were carried out at the Institute of Biological Production Systems, Leibniz Universität Hannover, Germany during 2008/2009 and 2009/2010 growing seasons to study the influence of the osmotic adjustment (OA) capacity, relative water content (RWC) and specific leaf area (SLA) on tolerance to drought in 22 breeding lines, two parents and tolerant cultivar (Sahel 1) of br...

The genus Triticum includes bread (Triticum aestivum) and durum wheat (Triticum durum) and constitutes a major source for human food consumption. Drought is currently the leading threat on world's food supply, limiting crop yield, and is complicated since drought tolerance is a quantitative trait with a complex phenotype affected by the plant's developmental stage. Drought tolerance is crucial ...

this study was conducted over a three-year period (1998, 1999 and 2000) to evaluate some drought tolerance indices and their relations with sugar yield in some sugar beet genotypes under early season drought and non-drought conditions. the experimental design was a split plot with a randomized complete block. the main plots consisted of two irrigation regimes: non-stress and water stress in ear...

As a result of the rapid increase in world population, need for wheat, which is one main nutrition human diet, also rapidly increases. However, due to yield losses caused by abiotic stress factors such as drought, wheat production not sufficient. Therefore, genetic characterization studies performed on genotypes terms drought tolerance are important. In this study, regardingdrought was carried ...

this experiment was conducted to evaluate eight new sugar beet genotypes with different drought tolerance responses to three irrigation schemes (including normal irrigation and early season and continuous stressed) in motahari research station of sugar beet seed institute (sbsi),karaj,iranduring 2005-2006. the study was accomplished in a split plot design (irrigation schemes and genotypes as ma...
