Abstract Various resistances to salinity are due to plants genetically variations, and selection on the basis of one factor will not be a suitable criterion in measurement of resistance to salinity, therefore in choosing resistant varieties, it is necessary to notice to a set of resistant indexes to salinity, creating changes in physiology, anatomy and morphology of plant species. This resear...
In this study, the effect of dietary safflower extract supplementation was investigated on common carp survival and physiological response to salinity stress. To this, the fingerling fish with average weight of 9.51 ± 0/13 g were fed with diets containing 0, 0.5, 1.5 and 3 % safflower extract for 70 days. After this period, some fish were randomly exposed to water salinity of 20 g/l and their m...
pollen grains as well as whole plants of four olive (olea europaea l.) cultivars were screened for nacl salinity stress. different vegetative and physiological indexes of the cultivars were analyzed. leaf and root na/k ratio as well as stomatal resistance of plants exposed to salinity proved to be appropriate indexes of whole plant response to salt stress. whereas, in vitro pollen germination p...
To evaluate the tolerance to salinity in almond, this factorial experiment was conducted based on completely randomized block design with three replications in greenhouse of Agricultural and Natural Resources Research Center in East Azerbaijan province. The first factor included almond cultivars (Mangha, Nonpareil, Eskandar, Araz and Sahand), and the second factor was salinity levels (electrica...
in many studies, the medicinal properties and impact of blond plantain on mechanisms of human physical activities has been proven. salinity is an important abiotic stresses with detrimental effects on seed germination. an experiment was conducted to study germination characteristics of blond plantain under water and salinity stress conditions at different temperatures. the experiment was conduc...
in order to investigate effective morpho-physiological traits related to salinity resistance, and their relationship with grain yield as well as study of salinity tolerance and susceptibility indices in 169 barley recombinant inbred lines, a population of barley derived from a cross between arigashar and igri, this experiments were carried out using alpha lattice design with two replications d...
به منظور بررسی تاثیر فسفر بر رشد و ترکیب شیمیایی نهالهای پسته در شرایط شور، آزمایش گلخانهای در قالب طرح کاملاَ تصادفی به صورت فاکتوریل با سه تکرار صورت گرفت. تیمارها شامل شش سطح فسفر ( 0، 30، 60، 90، 120 و 150 میلیگرم در کیلوگرم خاک از منبع اسید فسفریک) و شش سطح شوری (0، 600، 1200، 1800، 2400 و 3000 میلیگرم کلرید سدیم در کیلوگرم خاک) بودند. نتایج نشان داد که افزایش سطوح شوری منجر به کاهش مع...

Chickpea (Cicer arietinum L.) is highly sensitive to salinity and selection of chickpea genotypes that are moderately tolerant to salinity can help to expand chickpea cultivation in saline areas. Eleven chickpea genotypes were grown in a hydroponic system containing different NaCl concentrations (8 and 12 dS m-1) and control (Hoagland solution) in order to study the effects of salt stress on ph...
to determine the relative salt tolerance and/or resistance in seedlings of pistachio genotypes, four pot experimentswere conducted. in experiments 1 and 2, the effects of salinity on growth indices were studid. experiments were donein the form of split plot based on rcbd. in each experiment, mainplots consisted of different electrical conductivitiesof irrigation water (eciws). in experiment 1, ...
