Enlarged root systems that extend into the salt affected soil improve water and nutrient capture by plants and can increase plant productivity. In order to examine root system characteristics of four bread wheat cultivars contrasting in salt tolerance (Arg, Ofoq, Tajan and Morvarid) a greenhouse experiment was conducted with applying two salinity levels (0 and 150 mM NaCl) on plants grown in PV...
Salt stress is one of the main abiotic stresses for rice that causes negative effects on its growth and productivity. In present study, effects of salt stress on differential gene expression of some genes which are responsible in salt stress were investigated in two rice tolerant and sensitive genotypes (FL478 and IR29) by applying cDNA-AFLP technique. Among the TDFs (Transcript Derived F...
Potassium-argon analysis by stqwise dissolution provides a way to measure in detail the distribution of argon isotopes and potassium in rock salt. The method can be used for salt that contains only trace amounts of potassium, because the potassium and argon in detrital silicates within the salt are not released during the dissolution. Water may be used as the solvent when relatively large a...
Soil salinity is one of the most critical factors reducing crop yield. SOS signaling is one of the significant pathways that regulate ion homeostasis and it has the important role in mechanism of plant resistance to environmental stresses such as salt stress. Roots are the first organ of plants exposed to salt, so the role of genes involved in this pathway and their relation to salt tolerance w...
the biosorption of hexavelent chromium from saline solutions by posidonia oceanica, a marinebiomass, was studied as a function of ph, initial chromium (vi) and salt (nacl) concentrations in batchsystem. the sorbent exhibited the maximal chromium (vi) uptake at ph 2 regardless of the presence ofincreasing salt concentration. equilibrium uptake increased with chromium (vi) concentration up to 250...
because of large-scale dry regions, salt marsh monitoring is necessary using of remote sensing data's. the aim of this study is to monitor salt kashan using of satellite data's processing. therefore, the satellite images of lissiii sensor were used. initially, the technique of color composite images envi4.8 software was used to clearly distinguish salt. then, principal component analy...
Background and Objective: There is a direct relationship between high intake of salt and increased risk of many non-communicable diseases. The aim of this study was to determine the self-efficacy and readiness of women to reduce discretionary salt consumption. Materials and Methods: This cross-sectional study was conducted in 2016 using a self-administered questionnaire on 561 women at...
Background: Cardiovascular diseases (CVDs) are the leading cause of premature death in the 21st century. Dietary factors, such as high salt intake, are related to increased risk of CVDs{Akpolat, 2009 #21}. One of the main sources of dietary salt is bread. On the other hand, salt content is a quality indicator of bread. Therefore, this study was conducted to evaluate the salt content in a variet...
Salt crystallization is one of the most powerful weathering agents that may cause a rapid change in the mechanical properties of stones, and thus limit their durability. Consequently, determining the mechanical properties of stones due to salt crystallization is important for natural building stones used in marine environmental and mild climatic conditions, which expose excessive salt crys...
