in order to study the effects of a superabsorbent polymer on yield and yield components of dry land wheat cultivars, a field experiment was carried out in factorial arrangement using randomized complete block design with four replications on research field in khomein city, during 2010-2011 cropping season. the experimental factors included three dry land cultivars called azar2, sardari, rasad a...

in recent years, the russian wheat aphid, has been included worldwidely in the list of the important pests of cereals, particularly wheat plants. in addition to direct serious damage, the aphid is the main vector of barley yellow dwarf, barley mosaic, and sugarcane mosaic viruses. the pest was reported from east azarbaidjan province (iran) a few years ago and it is now widespread in tabriz,...

Drought is the cause of adverse environmental impacts on plant growth and crop yield. In this study, the effects of water deficit on plant molecular and physiological responses were investigated using two cultivars (namely, Sardari and Zarin) of bread wheat selected based on the results of a three-year research. For the purposes of this study, they were grown in plastic pots containing field so...

a split plot experiment based on randomized complete block design (rcbd) with three replications was conducted in 2012,treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (sardari, rijav, biseton and rashid) as the second factor. plant characteristics such as plant height, length o...

a study was performed to study the effect of drought stress on protein changes of five wheat genotypes. wheat genotypes were planted in early november, growing season of 2008-2009. the experiment was carried out in a factotial design with three replications. two drought stress levels (irrigated and non irrigated) and five genotype of wheat (f103-l-1-12//pony/opata, f1.158/fdl//blo/3/sh14414/cro...

this study was performed to investigate the photosynthetic partitioning pattern of materials to aerial parts of bread wheat in dryland conditions. it was as well to study its relationship with bread wheat resistance and grain yield in drought conditions. seven genotypes including two cultivars (azar2, sardari) and five lines were investigated in a field experiment through a randomized complete ...

cold is one of the most important abiotic stresses in some regions of iran. to investigate of some tolerance related traits to cold condition, 22 bread wheat genotypes planted in ardabil region in 1980. after plants passed winter cold condition (135 freezing days), cell membrane stability, chlorophyll content of leaf and crown depth and grain yield of genotypes were measured. anova analysis sho...
