objective: knowing about cognitive dissonance aspects and psychological components will be helpful not only in psychological field but also in commercial and political areas. therefore the aim of this study was evaluation of relation between personality and physiological components of cognitive dissonance. method: 130 students of elmi-karbordi university of safadasht were invited and they wer...
the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...
Salinity stress is an important challenge for wheat production in the world. Plant growth promoting rhizosphere bacteria, isolated from halophytic plants, can increase the tolerance of crop plants to salinity by direct and indirect mechanisms. In this study, plant growth-promoting traits of bacterial strains (Bacillus safensis, Bacillus pumilus and Zhihengliuella halotolerans), isolated from th...
Understanding how plants respond to environmental gradients and influence ecosystem functions remains a core challenge in ecology. Across species ecosystems, have been shown coordinate leaf, stem, root traits along gradient with optimal resource acquisition or conservation strategies at its extremes, termed the plant economic spectrum (PES), turn driving functioning. PES theory has successfully...
Salinity is one of the environmental factors that has a critical influence on plant growth and development. Researchers have shown that some plant growth regulators such as nitric oxide improves the plants resistance to environmental stresses such as salinity, heat, cold and drought. Sodium nitroprusside (SNP) commonly was used as a nitric oxide (NO) donor in plants. The aim of this resea...
in order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(triticum aestivum l.), an experiment was carried out at the experimental farm of shiraz university. results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...
in order to investigate the effect of zinc element application on growth and some morphophysiological of maize (single cross 704) an experiment was conducted during 2010 at greenhouse. experimented design was complete randomize factorial with four replications. treatments of experiment were soil salinity (4, 8 ds.m-1 and 0 as a control) and different zinc concentration including 0, 10 and 20 mg...
salinity stress is one of the most important abiotic stresses which threaten plants. in order to study the effect of salinity stress on yield and yield components of sunflower and also genetic analysis of these traits in relation with salt tolerance, a factorial experiment based on a completely randomized design with three replications was conducted. pots were arranged outside the greenhouse in...
background: as moringa peregrina is a valuable medicinal plant in traditional medicine, it is necessary to determine responses of this plant to salinity. objective: to determine some biochemical and growth responses of moringa peregrina to salinity at the seedling stage. methods: this experiment was conducted in institute of medicinal plants-acecr, on base of factorial experiment as completely...
Salinity stress is considered as one of the major factors that reduce plant growth in many regions in the world. Agropyron pectiniforme and Agropyron trichophorum species are perennial grasses species that product valuable forage and grazing material in pasture and rangelands of Iran. The aim of this study was determining effect of salinity stress with NaCl on seed germination traits of Ag. pec...
