A novel salinity proxy based on Na incorporation into foraminiferal calcite [PDF]

open access: yesBiogeosciences, 2013
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 ...

Salinity control on Na incorporation into calcite tests of the planktonic foraminifera Trilobatus sacculifer – evidence from culture experiments and surface sediments [PDF]

open access: yesBiogeosciences, 2018
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]

open access: yesDesert, 2021
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

A Short Review on the Development of Salt Tolerant Cultivars in Rice [PDF]

open access: yes, 2016
Rice is staple food for half of the world. With a population of almost 9.6 billion by the year 2050, there is a dire need of developing techniques to improve the crop plants, not only in terms of better yield but also to withstand harsh environmental ...

Contrasting Responses of Guar Genotypes Shed Light on Multiple Component Traits of Salinity Tolerance Mechanisms

open access: yesAgronomy, 2021
Guar (Cyamopsis tetragonoloba (L.) Taub.) is a legume crop, and gum derived from its seeds has various industrial applications. Due to its tolerance to various abiotic stresses, guar can be grown under water-deficit or high-salinity conditions.
