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...

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...
