In order to study the correlation of agronomic, morphologic and physiologic traits and their effects on grain yield of rice genotypes in two environments (favorable irrigation and water stress), 49 genotypes were evaluated using a completely randomized block design with 3 replications in two experimental conditions. All practices and conditions were the same for the two experiments with the exc...

In order to study the relationships among traits and grouping genotypes of wheat, 11 promising lines of winter wheat along with Orum, Zareh, Mihan, Zarrin  and peshgam  cultivars were evaluated under two levels of irrigation (complete irrigation and cutting irrigation from flowering to maturity) at Agricultural Research Station of Miandoab during 2013-2014 and 2014-2015 growing seasons. The exp...

In order to identify drought stress tolerance in rapeseed, nine commercial rapeseed cultivars (Opera, Karaj1, Karaj2, Karaj3, Zarfam, Okapi, Talayeh, Licord and Modena) were evaluated under two conditions (normal and drought stress) in Kangavar region in the west Iran in 2014-2015 growing season. This research was carried out in a split plot experiment based on completely randomized design in f...

In order to evaluate the effect of terminal moisture stress on 20 barley promising lines (Hordeum vulgare) and for determination of their relative tolerance, an experiment was conducted based on randomized complete blocks design with three replications in growing season of 2010-2011. In this research some old indices such as, stress susceptibility index (SSI), tolerance index (TOL), mean produc...

  This experiment was designed to determine the role of vitamin E and coenzyme Q10 antioxidant on immunity of broilers in cold stress conditions. For this purpose, 500 male chicks in a completely randomized design with 5 treatments, 5 replicates and 20 chicks in each replicate were tested in 25 experimental units. Treatments were: positive control (normal conditions growth without antioxidants)...

background and objectives: rice plant requires abundant water during its growth cycle and usually faced with water deficit. drought  stress alters the allocation assimilate , root and shoot growth during the vegetative period and also lower tillering, death tillers, lower plant height and flowering delay. the aim of this study was to screen different iranian genotypes and some lines from irri w...

One of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. In order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...
