in wheat na+ exclusion and k+/na+ have shown to be associated with salinity tolerance, therefore in order to identify qtls with additive effect for na+ and k+ concentration traits in roots and shoots of wheat, 319  bread wheat recombinant inbred lines (ril f7), derived from a cross between roshan cultivar (salt tolerant) and falat cultivar (salt sensitive), along with their parents and 2 checks...

salinity stress is one of the most important abiotic factors that restrict the growth and yield of many plants. salinity can increasingly influence the host susceptibility, occurrence and development of plant diseases due to its negative effects on the host plants. mycorrhizal fungi are able to increase the tolerance of some plants to salinity. in this study, the biological effects of glomus mo...

The effects of shading in combination with salinity treatments were studied in citrus trees on two rootstocks with contrasting salt tolerance to determine if shading could reduce the negative effects of salinity stress. Well-nourished 2-year-old 'Valencia' orange trees grafted on Cleopatra mandarin (Cleo, relatively salt tolerant) or Carrizo citrange (Carr, relatively salt sensitive), were grow...

Miscanthus is a woody rhizomatous C4 grass that can be used as a CO2 neutral biofuel resource. It has potential to grow in marginal areas such as saline soils, avoiding competition for arable lands with food crops. This study explored genetic diversity for salt tolerance in Miscanthus and discovered mechanisms and traits that can be used to improve the yield under salt stress. Seventy genotypes...

The ability of bacteria to adapt to external osmotic changes is fundamental for their survival. Halotolerant microorganisms, such as Tistlia consotensis, have to cope with continuous fluctuations in the salinity of their natural environments which require effective adaptation strategies against salt stress. Changes of extracellular protein profiles from Tistlia consotensis in conditions of low ...

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. osmotic pressure of leaf sap and intracellular osmotic pressure...

As the plant hormone abscisic acid (ABA) is involved in responses to salinity stress. We tested its putative relationship with the degree of tolerance to this abiotic stress. For this purpose we examined the responses of sensitive (IR29) and tolerant (IR651) varieties of indica rice (Oryza sativa L.) to a range of salinity (0 (control) and 100 mM NaCl). Shoot and root dry weight was reduced and...
