both poor germination and crop establishment due to water stress and salinity are among the most important limitations for production in semi-arid regions such as iran. to evaluate the response of four genotypes of triticale (et-82-15، et-82-8، et-79-17 and juanillo-92) to different water potentials caused by salinity and/or drought and recognizing the germination and seedling establishment, a ...

Ocean acidification is a threat to many marine organisms, especially those that use calcium carbonate to form their shells and skeletons. The ability to accurately measure the carbonate system is the first step in characterizing the drivers behind this threat. Due to logistical realities, regular carbonate system sampling is not possible in many nearshore ocean habitats, particularly in remote,...

Salinity is an important property of industrial and natural waters. It is defined as the measure of the mass of dissolved salts in a given mass of solution. High salinity has an impact on people and industries reliant on water. High levels of salt can reduce crop yields, limit the choice of crops that can be grown and, at higher concentrations over long periods, can kill trees and make the land...

Groundwater is one of earth’s most vital renewable and widely distributed resources as well as an important source of water supply worldwide. The increased exploitation of groundwater resources can decrease regional water quality as a whole. The estimation of sodium adsorption ratio (SAR) and chloride content, and also, Na, Ca and Mg concentration are much more timeconsuming and expensive than ...

Halophyte, like Salicornia europaea, could make full use of marginal saline land for carbon fixation. How the photosynthesis of S. europaea is regulated under high salinity implicates a significant aspect to exploit this pioneer plant in future. Measurement of photosynthesis parameters demonstrated the reduction of photosynthesis for the 0 and 800 mM NaCl treated plants are more likely due to n...

the present study was laid out in order toevaluate the effect of salinity on some biochemical characterize of grapevine c.vyaghouti. the experiment was done at agricultural and natural resources research center, ilam, iran at 2014. the experiment was a completely block design (crd) with four replications. saline factor was nacl salinity in seven levels (zero, 50, 100, 150, 200 and 250 mm). grap...

  Shrimp farmers have been suffering from loss of production due to White Spot Disease (WSD) in the last decades. A few studies focused on the environmental factors predisposed WSD. Our study aimed to investigate the effects of the different salinities on occurrence of WSD. The treatments were 30 ppt, 40 ppt and 50 ppt in triplicate and corresponding untreated control groups. White Spot Virus (...
