salinity is one of the most important limiting factors for crops, because of most agronomic and horticultural crops are sensitive to salinity. on the other hands, considerable lands of the world were affected by salinity and they are increasing day by day. an experiment was conducted with five levels of irrigation water salinity in soilless culture and greenhouse condition to evaluate the effec...
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
Soil salinity is one of the important and determinant factors in land degradation and desertification. This study was undertaken to investigate salt tolerance in Salsola tomentosa under greenhouse conditions to choose a suitable species for saline conditions. The treatment solutions for salinity tests were different concentrations of NaCl (0, 100, 200, 300, 400, and 500 mM) with three replicate...
salinity is one of the most limitation factors for crop production in agricultural systems due to the toxic effects and preventing water and nutrients absorption, in this research the efficiency of four strains of fluorescent pseudomonads on concentration of nutrient elements in rice was determined, under saline conditions. a pot experiment was carried out based on the factorial completely rand...
The effect of four water salinity levels (0.75, 5, 10 and 15 dS.m -1 ) on growth indices and physiological parameters in some wild pistachio (P. atlantica, P. atlantica subsp. kurdica, P. atlantica subsp. mutica and P. atlantica subsp. cabulica) were investigated under greenhouse conditions. Leaf dry weight was reduced to about 30-54% at ECw 10 dS.m -1 . Chemical analysis of shoot and root indi...
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...
to study the effects of foliar application of common and nano-sized iron sulphate on five sunflower cultivars (alster, olsion, hysun36, yourflour and hysun33) under two levels of salinity (0 and 100 mm nacl), a pot experiment in factorial based using a randomized complete block design with three replications was conducted. plant height, leaf area, shoot weight, chlorophyll content and the conce...
monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
abstract salinity tolerance is one of the major factor influencing crop productivity in arid and semi-arid areas. the salinity tolerance of fruit trees can be enhanced through the use of tolerant rootstocks. this experiment was conducted to investigate the effects of salinity stress and rootstock on the growth, photosynthetic rate and nutrient concentrations of almond (prunus dulcis miller.) cv...
In order to evaluate the salinity tolerance of six pomegranate genotypes including Malas Dane Ghermez Esfahan, Malas Yazdi, Shirin Shahvar, Meykhosh Yazd, Malas Saveh and Malas Yousofkhani, a greenhouse experiment was conducted as a factorial based on randomized complete block design with five salinity levels of 0, 25, 50, 75 and 100 mM sodium chloride at Agricultural College of Lorestan Univer...
