In a series of studies conducted in Malawi to determine the effects of different salinity concentrations on survival, growth, feed conversion, reproduction, and whole-body composition of five taxonomic groups of tilapia—Oreochromis shiranus chilwae (Lake Chilwa strain), O. shiranus chilwae (Bunda College strain), O. karongae, O. shiranus shiranus, and Tilapia rendalli—it was observed that the f...

This study was carried out to determine the tolerance of grass pea genotypes salinity stress at callus and seedling stages under in vitro conditions. The calli seedlings six selected tolerant based on primary screening field were separately exposed treatments (0, 125 mM) vitro. Salinity imposed with NaCl during culture, it significantly affected all traits. Genotype Iran had lowest dry weight t...

The ability to quantitatively assess ecological health is of great interest to those tasked with monitoring and conserving ecosystems. For decades, biomonitoring research and policies have relied on multimetric health indices of various forms. Although indices are numbers, many are constructed based on qualitative procedures, thus limiting the quantitative rigor of the practical interpretations...

Salinity stress declines plant growth and its efficiency, which is leading to a substantial reduction in crop yield. Presently, the worldwide challenges are meet food consumption demand, along with decreasing productivity per unit area at same time of environment. Wheat (Triticum aestivum L.) one major cereal grain crops losses gain yield exceeds 60% due salinity stress. Now, it imperative deve...

Abstract The development of energy recovery device (ERD) is a decisive factor for the recent prevalence reverse osmosis (RO) technology in seawater desalination field. Unlike broadly studied large scale ERDs, investigations small ERDs are scarcely reported, especially on performance fluctuations under variable operating conditions. Based an authors’ exploratory research piston type integrated h...

Objective of this study was to evaluation Changes in proline, catalase and germination characteristics of barley seeds under salinity stress. Salinity stress at osmotic potentials of 0 (as control), 4, -8, -12 and -16 bar were adjusted using NaCl before the start of the experiment. Our results showed that, the effect of salinity levels for all traits was significantly. With, increases of salini...

introduction salinity is an important abiotic stress that reduces the crop production potential and the efficiency of plants in arid and semi-arid regions. soil salinity can be increased by irrigation, inappropriate drainage, sea advancement to coastal regions and the accumulation of salts in desert and semi-desert regions. salinity is a limiting factor for plant growth because it limits the fe...

This study aimed to assess ecological quality status of hard substratum macroinvertebrates communities of the Caspian Sea with three ecological indices and their relation with environmental factors. For this purpose benthic communities of the Caspian Sea basin were studied seasonally during 2014 in 8 sampling sites. Temperature, salinity, dissolved oxygen, pH, nitrate, nitrite, silicate and pho...

Salinity reduces substrate water potential, thereby restricting water and nutrient uptake by plants; salinity may also cause ionic imbalance and toxicity. Because substrate salinity fluctuates through the growing season, a plant may be exposed to different salinity levels, at various stages of development, with potentially significant consequences on population dynamics. Here, we present the re...
