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...

Salinity is an important constraining factor in the way of crop production around the world. Plant nutrition management could alleviate the harmful effects of salinity. In order to evaluate the interaction effects of Zinc availability and different levels of salinity, an experiment was conducted using four levels of zinc(0, 10, 20 and 40 mg/kg) and three levels of NaCl salinity of irrigation wa...

The effect of acclimation salinity and salinity changes on the concentration of high-energy phosphate metabolites and arginine kinase (AK) flux was examined in vivo in juvenile blue crabs using 31P-nuclear magnetic resonance (NMR). Crabs were acclimated for 7 days to a salinity of 5 or 35 per thousand and then placed in a flow apparatus that could sustain the animals while NMR spectra were acqu...

Cotton (Gosspium hirsutum L.) is classified as a salt tolerant crop. However, its yield and fiber quality are negatively affected by soil salinity. Studies on the enzymatic differences in sucrose metabolism under different soil salinity levels are lacking. Therefore, field experiments, using two cotton cultivars, CCRI-79 (salt-tolerant) and Simian 3 (salt-sensitive), were conducted in 2013 and ...

Ecotones represent locations where vegetation change is likely to occur as a result of climate and other environmental changes. Using a model of an ecotone vulnerable to such future changes, we estimated the resilience of the ecotone to disturbances. The specific ecotone is that between two different vegetation types, salinity-tolerant and salinity-intolerant, along a gradient in groundwater sa...

Black tiger shrimp, Penaeus monodon (Fabricius) is a non-piscine organism becomes most important aquatic resource of Bangladesh in the last decades. Traditionally it cultured 15-30 ppt salinity. Effect different low salinity on its survival, growth, production and economic return was observed three levels 10 ppt, 7 5 for 110 days. Juvenile shrimps (approximately 5g each) were stocked at 4 m-2 d...

Soil salinity problems are widespread around the globe with increased risk of spreading over the years. The fungus Piriformospora indica, identified in Indian Thar desert, colonizes the roots of monocotyledon plants and provides resistance towards biotic as well as abiotic stress conditions. We have identified a cyclophilin A-like protein from P. indica (PiCypA), which shows higher expression l...

salinity affects the yield and quality of fruits crops as result of modifying water and nutrient uptake. in split root system, it should be possible to reduce the deleterious effect of salinity on the plant growth. therefore, an experiment was conducted on strawberry with different concentration of nacl (0, 30, 60 and 90 mm) in a completely randomized blocks design in studding hydroponic greenh...

changes of ions (na+, cr, k+), osmolarity and water concentration of body tissue, size and number of gill chloride cells as well as mortality percentage of the juveniles caspian roaches in weight groups of0.2, 0.5 & 1g water satiny stress were studied. the salinities tested  were 0 (fesh water), 7, 12.5 & 16g/lit and the assessments were completed 0, 12, 24, 48 & 72 hours after exposure. result...

Marine environments are unique habitats for microorganisms and represent uninvestigated areas that possess valuable resources. Fungi may also be important because they contribute to marine ecosystems as decomposers. The aims of this study were to investigate the halotolerance of marine-derived fungi and their enzymatic properties. Eighteen fungal strains representing 11 different species were u...
