Water shortage in the arid-semiarid regions of China seriously hampers ecosystem construction. Therefore, elucidation of the mechanisms by which vegetation in that area responds to drought stress may enable us to improve utilization of limited water resources and thus contend with the problem of drought and water shortage. We studied Bothriochloa ischaemum, a native grass species, conducted pot...

responses of twenty chickpea genotypes to drought stress were evaluated in the farm of college of agricultutre, razi university, kermanshah, iran in 2006-2007. the experiment was carried out in randomized complete block design with three replications under two water stress and non-stress conditions. the results showed significant differences among the genotypes for most of the traits. maximum y...

Tolerant and susceptible durum wheat varieties were grown in the 1 and 2 settlement zone under rainfed conditions inDaraa province-Syria, In order to expose plants to different level of water regime, since the two zones differ in total amount of rainfall during the growing season. Plants were suffered from terminal drought stress in both zones, however, the drought was more sever in the 2 settl...

to evaluate the effects of water deficit stress in barley germplasm collection of national gene bank ofiran, 25 genotypes collected from arid and semi arid provinces of iran and 3 sample cultivars werestudied in two environments including: non-stressed and water deficit stress. agronomical, phenologicaland morphological traits were measured. stress indices were calculated to determine tolerant ...

in order to evaluate the effect of different levels of drought stress on some physiological parameters in grapevine, a potted experiment with iranian grapevine cultivars ‘sahani’, ‘bidane-sefid’ and ‘farkhii’ was conducted in summer of 2008. the experiment was performed while employing four drought stress (water potential of soil, ?s= -0.2, -0.6, -1, -1.5 mpa) treatments each in three replicati...

in order to evaluate of physiological traits, related to drought tolerance, an experiment was carried out in controlled condition. the experiment was conducted to assess the effect of drought stress on photosynthesis, chlorophyll fluorescence and photosynthetic pigments in two tolerant genotypes (mcc392 & mcc877) and two susceptible genotypes (mcc68 & mcc448) were grown in drought stress (25% f...

drought stress in plants, the change (increase or decrease) in the production of plant proteins. proteomics in recent years one of the most powerful tools that help us to study the changes in protein in order to investigate the proteome of wheat leaves in response to terminal drought, two genotypes susceptible and resistant wheat genotypes were evaluated under irrigated (non-stress) and rain-fe...
