Povijest, degradacija i ekološka obnova priobalne močvare Saline na Brijunima

2023
The Saline coastal wetland covers an area of 12 hectares on the island of Veli Brijun within the Brijuni National Park. This anthropogenic habitat has high ecological potential and consists of three saline ponds endangered by the current climate change manifestations and local influences, in particular interruptions of water supply from the local water

Importance of Na content and water status for growth in Na-salinized rice and tomato plants

Soil Science and Plant Nutrition, 1998
Abstract The effect of a high Na content in plant on rice (Oryza sativa L. cv. Yamabiko) and tomato (Lycopersicon esculentum Mill cv. Saturn) growth was investigated. The high Na content was achieved by the supply of NaCI (rice: R1: 40, R2: 60, R3: 80, R4: 100, R5: 120; tomato: R1′: 10, R2′: 20, R3′: 40, R4′: 60, R5′: 80 mmol( + ) kg-1) to the nutrient

Leaf K/Na ratio predicts salinity induced yield loss in irrigated rice [PDF]

Euphytica, 2000
Summary Salinity is a major constraint to irrigated rice production, particularly in semi-arid and arid climates. Irrigated rice is a well suited crop to controlling and even decreasing soil salinity, but rice is a salt-susceptible crop and yield losses due to salinity can be substantial.

Physiological and Molecular Responses to Salinity Due to Excessive Na+ in Plants

2021
Salinity due to excessive sodium ions in plants is amongst one such abiotic stresses that are severely hampering crop productivity. Most plants are severely affected by excess sodium ions in soil. This abiotic stress creates relatively more problems in plants belonging to glycophytes group than the ones to halophytes group by interrupting their ...

Isotope Techniques to Study Kinetics of Na+ and K+ Transport Under Salinity Conditions

2012
Radioisotopes (particularly (22)Na, (24)Na, (42)K, and (86)Rb) have been used for many decades to trace the fluxes and accumulation of sodium and potassium ions in plant tissues. In this article, standard procedures for the tracing of ion fluxes are described, with emphasis on special problems encountered when examining K(+) and Na(+) transport under ...

Wheat grain yield on saline soils is improved by an ancestral Na+ transporter gene

Nature Biotechnology, 2012
The ability of wheat to maintain a low sodium concentration ([Na(+)]) in leaves correlates with improved growth under saline conditions. This trait, termed Na(+) exclusion, contributes to the greater salt tolerance of bread wheat relative to durum wheat.

Decreased Myocardial Na+K+ATPase Activity in Rats with Reduced Renal Mass-Saline Hypertension

Journal of Hypertension, 1985
Inhibition of cardiovascular Na,K-pump activity has been shown to promote an increase in the contractile activity of myocardial and vascular smooth muscle and a consequent rise in blood pressure (BP). It has also been shown that vascular Na,K-pump activity and myocardial Na+K+ATPase activity [the energy source for active sodium (Na) and potassium (K ...

Perturbation of Na+ and K+ gradients in human fibroblasts incubated in unsupplemented saline solutions

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1986
Changes in the intracellular concentrations of Na+ and K+ of fetal human fibroblasts have been followed after replacement of serum-containing growth media with unsupplemented and serum-supplemented saline solution (Earle's balanced salt solution). Incubation in unsupplemented salt solution was followed by a progressive increase of the internal Na ...

[Effects of salinity and Na+/K+ in percolating water from saline-alkali soil on the growth of Litopenaeus vannamei].

Ying yong sheng tai xue bao = The journal of applied ecology, 2008
In order to develop shrimp farming with the percolating water from coastal saline-alkali soil, the effects of the salinity and Na+/K+ in this percolating water on the survival, growth, metabolism, and glutamic oxaloacetic transaminase (GOT), glutamicpyruvic transaminase (GPT) and Na+-K+-ATPase activities of Litopenaeus vannamei were investigated.
