A novel salinity proxy based on Na incorporation into foraminiferal calcite [PDF]
Salinity and temperature determine seawater density, and differences in both thereby control global thermohaline circulation. Whereas numerous proxies have been calibrated and applied to reconstruct temperature, a direct and independent proxy for ...

Additive effects of Na+ and Cl– ions on barley growth under salinity stress [PDF]
Soil salinity affects large areas of the world's cultivated land, causing significant reductions in crop yield. Despite the fact that most plants accumulate both sodium (Na(+)) and chloride (Cl(-)) ions in high concentrations in their shoot tissues when grown in saline soils, most research on salt tolerance in annual plants has focused on the toxic ...

Salinity controls on Na incorporation in Red Sea planktonic foraminifera [PDF]
AbstractWhereas several well‐established proxies are available for reconstructing past temperatures, salinity remains challenging to assess. Reconstructions based on the combination of (in)organic temperature proxies and foraminiferal stable oxygen isotopes result in relatively large uncertainties, which may be reduced by application of a direct ...

Linking salinity stress tolerance with tissue-specific Na+ sequestration in wheat roots [PDF]
Salinity stress tolerance is a physiologically complex trait that is conferred by the large array of interacting mechanisms. Among these, vacuolar Na+ sequestration has always been considered as one of the key components differentiating between sensitive

Isoosmotic Regulation of Cotton and Peanut at Saline Concentrations of K and Na [PDF]
Peanut (Arachis hypogaea L.) and cotton (Gossypium hirsutum) plants were grown for 4 weeks in saline, isoosmotic rooting substrates with different proportions of K and Na. Isoosmotic media did not affect growth (except at the highest external K concentrations) or estimates of intracellular osmotic pressure in expanding leaves (i.e.

Genetics of Na+ exclusion and salinity tolerance in Afghani durum wheat landraces [PDF]
Selecting for low concentration of Na+ in the shoot provides one approach for tackling salinity stress that adversely affects crop production. Novel alleles for Na+ exclusion can be identified and then introduced into elite crop cultivars.We have identified loci associated with lower Na+ concentration in leaves of durum wheat landraces originating from

Salinity control on Na incorporation into calcite tests of the planktonic foraminifera Trilobatus sacculifer – evidence from culture experiments and surface sediments [PDF]
The quantitative reconstruction of past seawater salinity has yet to be achieved, and the search for a direct and independent salinity proxy is ongoing. Recent culture and field studies show a significant positive correlation of Na∕Ca with salinity in

The effect of salt stress on yield and accumulation of some minerals in two salt-tolerant and susceptible onion cultivars [PDF]
Salt stress is a major agro-environmental constraint on crop productivity. In this study, the effect of different levels of salinity stress (0,25,50,75, and 100mM NaCl) on the accumulation of some ions in two salt-tolerant and susceptible onion cultivars
