to investigate the effect of salicylic acid (sa) on salinity tolerance of two sugar beet cultivars, this experiment was conducted as split factorial based on a randomized complete block design with three replications during growing seasons of 2012 and 2013 in research farm of shahid chamran university. the studied factors were three levels of sa (0 mm, 0.5 mm and 1 mm), two levels of salinity (...
recent years have witnessed an increased attention to form focused instruction and consciousness raising activities (ellis, 2002; doughty & williams, 1998) on the one hand and extensive and meaningful exposure to the target language (klapper & rees, 2003; day & bamford, 1998) on the other. due to significance attributed to above mentioned issues by scholars, this study attempted to bridge them ...
This study aimed to investigate the effects of mild salinity stress on some physiological traits and metabolic profiles rice during seedling stage. Three cultivars differing in response, ‘KDML105’ (salt-sensitive, local Thai jasmine rice), ‘IR29’ (salt-sensitive ‘Pokkali’ (salt-tolerant were subjected by flood-irrigated with 40 mM NaCl. Salinity significantly reduces growth biomass sensitive cu...
the objective of this experiment was to determine the effects of different levels of nitrogen (n) and salinity on biochemical mechanisms of two wheat genotypes. a field experiment was carried out in a three replicate rcbd split factorial experiment in salinity station of college of agriculture, ferdowsi university of mashhad, iran in 2007-2008 and 2008-2009. three levels of salt stress (1.3, 5,...
introduction salinity has various effects on plant growth by affecting physiological processes. the decline in plant productivity under saline condition, frequently linked with the reduction of photosynthetic capability. it has been reported that efficiency of psii photochemistry (fv/fm) of numerous plant species have been decreased due to salt stress studies have shown that salicylic acid (sa...
the present study was an attempt to determine the types of motivation and levels of foreign language learning anxiety among efl students studying at azad and state universities in kermanshah and to determine the relationship between these two factors and language proficiency and gender. to this end, the foreign language learning motivation scale, by deci and ryan )1985(, were administered to 12...
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 the study of the salinity effects on seed germination and effecting parameter of fennel (foeniculum vulgare) was conducted a factorial experiment in a completely randomized design with two factors and three replications. factor a was 10 ecotypes, including; sardasht, saghghez, kerman, tabriz,sabzevar, rome, khusf, bojnoord, mashhad and shabestar and factor b was five concentrations ...
fenugreek is one of the important medicinal plant that used in the pharmaceutical industry. in order to investigate the effects of salinity stress on relative water content, membrane stability, total chlorophyll, sodium, potassium, sodium to potassium ratio and proline, a factorial experiment was conducted in a completely randomized design with three replications in 2013. experimental treatment...
Plant growth promoting rhizobacteria are known as an alternative to chemical fertilizers, which are able to reduce the harmful effects of non-biological stresses such as salinity and increase soil fertility and crop production. This study was conducted to investigate the effect of inoculation of Pseudomonas fluorescens strain FY32 on a number of morphological characters in canola cultivars unde...
