plants and soil microbes are the main sources of most enzymes available in the environment. it is, therefore, anticipated that any change in the growth of soil biota in response to salinity, may reduce the synthesis and production of extra- and intra- cellular enzymes. as a result, a reduction in the growth of plants and the activity of soil microbes in saline environments may lessen the level ...

Convenient reading out and/or determination of ionic strength (IS) is of great significance for both scientific research and real life applications. We presented here a novel method for the rapid and sensitive IS assay based on the electrolyte-induced sensitive wavelength blueshifts of the reflection spectra of polyacrylate capped Fe3O4 magnetic photonic crystals (PA-Fe3O4-MPCs). For HCl, MgSO4...

In order to study the effects of different salinity levels on turnip (Brassica rapa L.), an investigation was conducted at Yasouj University, Iran, in 2010. The effects of four salinity levels including 1.92, 9.87, 19.6 and 21.94 ds m-1 (20:1 ratio of NaCl: CaCl2 in Hoagland solution) on germination, vegetative and maturity stages of turnip (Baherghan landrace) were investigated. The results re...

Thirty Atriplex lines were examined for potential habitat improvement and phytoremediation of selenium (Se) contaminated sites. Studies were conducted to determine the biomass production, Se accumulation, and resistance of each line to the beet armyworm, Spodoptera exigua, an agriculturally important insect. Plants were tested using three salinity treatments: (1) control, no Se; (2) NaCl and Ca...

Brine fluids have recently been of high interest to enhanced oil recovery process in both academia and industry. Both diluted formation brines specifically formulated were reported improve crude displacement porous rock, owing either their bulk salinity or brine-type. Mechanisms for such an improvement widely proposed, including microscopic interfacial phenomena: wettability alteration reductio...

Soil and water resources can be severely degraded by salinity when total salt input exceeds output in irrigated agriculture. This study was conducted to examine partitioning of Ca2+, Na+, and Cl- between soil and soybean [Glycine max (L.) Merr.] plants under different irrigation regimes with both field and modeling assessments. In drip and sprinkler treatments, the irrigation water was salinize...

 Background: As Moringa peregrina is a valuable medicinal plant in traditional medicine, it is necessary to determine responses of this plant to salinity.  Objective: To determine some biochemical and growth responses of Moringa peregrina to salinity at the seedling stage. Methods: This experiment was conducted in Institute of Medicinal Plants-ACECR, on base of factorial experiment as ...

salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. the present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (nitraria schoberi). thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...
