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...

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,...

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...

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 ...

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...

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...

This research was carried out to study the effect of ageing on antioxidant and biochemical changes of wheat (Triticum aestivum L.) seeds. The experiment laid out in completely randomized design (CRD) with four replications in Islamic Azad University, Boroujerd Branch, Boroujerd, Iran in 2015. The seeds of wheat (cv Sardari) were harvested at maturity and ageing treatments were done at 43° C wit...

Seed germination is an important growth phase in the plant life cycle that can be injured by osmotic stress. Germination is divided into three phases and many processes are initiated before radical protrusion. Many metabolic activities occur, especially in Sensu stricto germination phase since the seed embryo is a live organ, so differences in protein patterns are important in this phase. This ...
