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...

Blue crabs (Callinectes sapidus Rathbun) acclimated to a salinity of 2 approximately doubled in wet mass (excluding carapace) during the period from 10 h before moult to 2 h after moult. Both in blue crabs acclimated to 2 salinity and in crabs acclimated to 28 salinity, the drinking rate increased from approximately 0.4 ml 100 g-1 h-1 at 1 day prior to moult to approximately 8 ml 100 g-1 h-1 du...

plants for optimal growth requires absorb water and nutrients absorption from the soil. magnetic water downward movement of minerals and makes it easy for plants to absorb nutrients and water. this study was designed to investigate the effect of magnetic salt water on some quantity and quality characteristics of artichoke leaves. the experiment was factorial based on completely randomized desig...

salinity stress is one of the most important environmental constraints that have been limited agricultural production in iran. therefore, introducing suitable cultivars having desirable yield under salinity stress will lead to increase of production efficiency. in order to study the response of spring safflower cultivars to salinity, an experiment was carried out at the experimental station of ...

due to the lack of fresh water resources, the use of saline water for the production of plants such as wheat and kochia is inevitable. to sustain production, the effect of saline water on the plants and soil in each region must be studied. therefore in this paper, the effects of irrigation with saline water to produce plants such as wheat and kochia, as well as changes in the soil salinity prof...

The effects of water/oil volume ratio, type and concentration of demulsifier, water salinity and mixing speed on the average water droplets size in water-oil emulsion are evaluated at different times through NMR measurements.The type and concentration of demulsifier have the greatest effects on the average droplet size with 38% and 31.5%, respectively. The water/oil volume ratio, water salinity...

A detailed hydrographic survey of the water column of the Amazon shelf was performed using stable oxygen and hydrogen isotopes to determine the source and fate of waters on the shelf. δO-H2O and δD measurements were made on water column samples from approximately 60 stations (three depths per station) which were each collected during four Amasseds (A Multidisciplinary Amazon Shelf SEDiment Stud...

background and objectives: infunction of the photosynthetic apparatus of halophytes plays an important role in their salinity tolerance. kochia as a halophyte, is of high ability in biomass production in salinity stress conditions. thus study photosynthesis and the related factors salinity stress can provide appropriate physiological view for better understanding of the plant mechanisms of in s...
