introduction: almond (prunus amygdalus b.) is one of the most important crops consumed as a dry fruit and it is mainly adaptable to arid and semi-arid regions mostly suffering from salinity stress (8). soils with dry humidity regime are dominant in iran and in the world at large and mostly include regions with more evaporation than precipitation. this in turn leads to increased salinity of the ...

Plant group classification relation to soil environmental characteristics was monitored in Hangzhou Bay coastal wetland, China. 18 taxa, belonging to 17 genus and 7 family were recorded, and classified into five groups by TWINSPAN viz A, Scirpus mariqueter group, B, Spartina alterniflora group, C, Phragmites communis group, D, Tamarix chinensis P. communis group, and E, Salix matsudana Imperata...

For biomarkers to be useful in assessing anthropogenic impacts in field studies involving aquatic organisms, they should not be affected by naturally occurring changes in environmental parameters such as salinity. This is especially important in estuarine environments and for relatively unspecific biomarkers like heat-shock proteins (hsps, stress proteins). In this study, the heat-shock protein...

Internal phosphorus (P) mobilisation from aquatic sediments is an important process adding to eutrophication problems in wetlands. Salinisation, a fast growing global problem, is thought to affect P behaviour. Although several studies have addressed the effects of salinisation, interactions between salinity changes and nutrient cycling in freshwater systems are not fully understood. To tackle e...

A comparison is presented of remote and shipboard measurements of sea surface salinity made in the vicinity of the Delaware coastal current, a low salinity band with its source in the mouth of Delaware Bay. The remote sensing measurements were made from an aircraft with the Electronically Scanned Thinned Array Radiometer. The shipboard measurements were made with a thermosalinograph on board th...

A possible survival strategy for plants under saline conditions is to use some compounds that could alleviate the salt stress effect. One of these compounds is nicotinamide (vitamin B3/niacin). The effect of exogenous application of nicotinamide with different concentrations (0, 200 or 400 mg l-1) on faba bean (Vicia faba L.) plant grown at different NaCl levels (0, 50 or 100 mM) was investigat...

The reuse of saline wastewaters and groundwaters becomes a viable option for the irrigation of salt tolerant floral crops as competition for high quality water increases. A completely randomized design with three replications was used to assess the effects of two water ionic compositions and six salinity levels on the production and mineral accumulation of two cultivars of Celosia argentea var....

Photosynthetic gas exchange, modulated chlorophyll fluorescence, rapid fluorescence induction kinetics, and the polyphasic fluorescence transients were used to evaluate PSII photochemistry in the halophyte Suaeda salsa exposed to a combination of high salinity (100-400 mM NaCl) and heat stress (35-47.5 degrees C, air temperature). CO(2) assimilation rate increased slightly with increasing salt ...

Jiang, Y., J. Tang, X. Yu and J. Camberato. 2013. Growth and Physiological Responses of Diverse Perennial Ryegrass Accessions to Increasing Salinity. 2012 Annu. Rep. Purdue Univ. Turfgrass Sci. Progr. p. 7-11. Summary: Ten diverse accessions of perennial ryegrass (Lolium perenne L.) were grown in sand culture and exposed to a half-Hoagland solution amended with 0 (control), 50-, 100-, 150-, 200...

tolerant cultivars showing less growth reduction than sensitive cultivars under saline conditions (Qian et al., We evaluated leaf C isotope discrimination as affected by salinity 2001; Suplick-Ploense et al., 2002). Growth reduction among three Kentucky bluegrass (Poa pratensis L.) cultivars that differ in their salt tolerance. ‘Moonlight’, ‘NorthStar’, and ‘P-105’ under salt stress could be at...
