Current research on effect of increasing concentrations (0 (control), 100, 200, 300, 400 and 500 mM) of different salts including NaCl and Na2SO4 on germination and initial growth phase of Halostachys caspica were studied. The experimental design was completely randomized design with three replications. Characters of percentage, speed and index of germination, seed healthy index, radicle, plumu...

A strain of rats that will predictably develop experimental hypertension by means of different techniques was used to study NaCl-induced hypertension. Observations were continued for 1 year after weaning unless death intervened. Among groups of rats on 0.4, 1, 2, 4, and 8% NaCl chow, respectively, blood pressures generally rose as dietary NaCl increased. Average blood pressures ranged from 146....

This paper presents the printed thick film Ag|AgCl|KCl reference electrodes for electrochemical or biosensors application and their electrochemical and analytical performance. The reference electrode exhibits a stable potential against standard glass reference electrode with a potential difference of 5 mV in the deionized water. The anodic and cathodic peak current of the electrode increase wit...

In vitro chemotactic responses of infective third-stage larvae (L3) of Brugia pahangi to NaCl, Na2HPO4, KCl, K2HPO4, MgCl2 and CaCl2 were assessed. Compared to deionized water as a control, 200 mm NaCl and 100 mm Na2HPO4 significantly attracted L3 (P < 0.01 and P < 0.01), whereas L3 were likely to avoid 200 mm KCl and 100 mm K2HPO4 (P < 0.05 and P < 0.05). L3 showed no significant tendency to a...

The response of duckweed (Lemna minor L.) to salinity and osmotic stress was evaluated by monitoring growth and peroxidase activity every second day, for a period of 17 days. The nutrient medium was supplemented with isoosmolar concentrations of NaCl and mannitol (50 mM and 100 mM NaCl, 100 mM and 200 mM mannitol). Growth decreased markedly with increasing concentrations of NaCl and mannitol. T...

Salinity negatively affects plant growth and causes significant crop yield losses world-wide. Maize is an economically important cereal crop affected by high salinity. In this study, maize seedlings were subjected to 75 mM and 150 mM NaCl, to emulate high soil salinity. Roots, mature leaves (basal leaf-pair 1,2) and young leaves (distal leaf-pair 3,4) were harvested after 3 weeks of sowing. Roo...

Asparagus breslerianus a wild species in Iran, exhibited tolerance to salt in dry gypsum hills and dry lands. In order to check for salt tolerance thresholdvia in vitro conditions, the A. breslerianus callus was subjected to NaCl (sodium chloride) treatments. Six weeks old calli derived from male spear bud, were exposed to 0, 21.88, 43.76, 65.64, 76.58, 87.52, 109.40, 131.28, 153.16 and 175.04 ...

The effects of salinity (NaCl) stress on growth, cytosolic Ca(2+) gradients and cytosolic pH homeostasis of root hairs of Arabidopsis thaliana are assessed here. Neither cytosolic Ca(2+) nor pH at the hair apex were significantly affected by 20 min exposure of up to 90 mM NaCl or of up to 5 mM extracellular Ca(2+). Exposure to increasing NaCl concentrations, up to 90 mM, for 2 d or 6 d reduced ...

in order to study the effects of ascorbic acid as an important antioxidant reducing salinity damage, an experiment was conducted on two althernantera genotypes (“entire leaf” and “undulated leaf”) at research greenhouse of shahid chamran university in 2013. concentrations of 0, 0.5 and 1 mm of ascorbic acid were sprayed weekly on plants grown under 0, 30, 60, 90 mm nacl. the experiment was carr...

Dehydrated toads initiated water absorption response (WR) behavior and absorbed water from dilute NaCl solutions. With 200-250 mM NaCl, WR behavior and water absorption were both suppressed. With 200-250 mM Na-gluconate, WR initiation was significantly greater than with NaCl but water loss was greater. Neural recordings from spinal nerve #6 showed a greater integrated response to 250 mM NaCl th...
