Drought stress is one of the most important abiotic stresses influencing performance of crop plants. Therefore, the identification or development of tolerant genotypes is of high importance for incorporating in cotton production. In this study to evaluate the effect of drought stress on some cotton traits, 5 improved cotton varieties were studied in a split plot design with three replications i...

Globally, increasing water and energy demand is expected to reach 6.9 trillion cubic meters by 2030, exceeding 40% of the available supplies. Climate change rising temperatures caused shortages due lesser irregular rainfalls, leading lower production crops. The research assess drought tolerance Pima cotton (Gossypium barbadense. L) lines in Uzbekistan revealed line, T-450 as most promising for ...

one of the most effective ways to deal with drought stress and increase water use efficiency is the development of drought-tolerant varieties which display less reduction in yield per unit water reduction. therefore, the breeding of diploid pollinators was considered as an essential measure for producing drought-tolerant hybrids. in this study, from 4 diploid pollinator populations, 45 half-sib...

in order to study of drought stress on physiological and agronomicalcharacteristics of rapeseed varieties, an experiment was carried out as split plot basedon randomized complete block design with three replications at yazd region duringof 2011-2012. irrigation treatments was designed in two levels as main plot includingirrigation after 80 mm evaporation from evaporation pan, class a (control t...

in order to study of drought tolerance in bread wheat genotypes, this study was conducted in maragheh dryland agricultural research station. the study included two experiments and the statistical design of each experiment was a rcbd with four replications, and 20 bread wheat genotypes that were compared under drought stress (rainfed) and supplementary irrigation. analysis of simple variance sup...
