The study was made in order to evaluate the response of fifteen wheat genotypes (grown in Pakistan) to sodium chloride salinity at seedling stage keeping two levels of salinity (150 and 200 mM NaCl) along with a control (no application of salt). The effect of varieties on shoot length of wheat was non significant. Maximum shoot length was recorded in MH-97 (15.55cm) while minimum shoot length w...

Effects of salinity on growth and physiological indices of Kosteletzkya virginica seedlings were studied. Plant height, fresh weight (FW), dry weight (DW), and net photosynthetic rate (Pn) increased at 100 mM NaCl and slightly declined at 200 mM, but higher salinity induced a significant reduction. Chlorophyll content, stomatal conductance (Gs), intercellular CO2 concentration (Ci), and transpi...

Climate change, expanding soil salinization, and the developing shortages of freshwater have negatively affected crop production around world. Seawater salinized lands represent potentially cultivable areas for edible salt-tolerant plants. In present study, effect salinity stress on plant growth, mineral composition (macro-and micro-nutrients), antioxidant activity in dune spinach (Tetragonia d...

this research investigate the effects of different concentrations of salt: 0, 75, 100, 150 (mm nacl) and concentration of 0.05 mm gibberellic acid and 5µm salicylic acid on the content of proline and a, b chlorophylls of canola (hayola 401 and rgs). the results showed that with increasing in the amount of salinity in both chlorophylls decreased and the amount of decrease in chlorophyll b was mo...

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...

Despite the large interest in the use of Chenopodium quinoa as a crop on extreme habitats, very little is known about growth response and seed yield under saline conditions. As a prerequisite for its sustainable utilization in salt-affected areas, this study aimed to unravel individual physiological and morphological mechanisms that determine its salt tolerance. Hence, the plants were grown in ...

plasma membrane h+-atpase is a major integral membrane protein with a role in various physiological processes including abiotic stress response. to study the effect of nacl on the expression pattern of a gene encoding the plasma membrane h+-atpase, an experiment was carried out in a completely random design with three replications. a pair of specific primers was designed based on the sequence o...

The most important development period in cereal plants is the initial stage, that is, seed germination and early seedling development. Even if barley thought to be a partially salt-tolerant plant, it may severely affected when exposed salinity at developmental periods. Pre-treatment preparation of seeds before sowing have an agriculture. Nano-seed priming treatment new approach used increase ge...

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...

Salinity is one of the most brutal environmental stresses that hamper crop productivity worldwide Approximately 10% of the total land surface is salt affected and about 10 million hectare of agricultural land is lost annually due to salinization and water logging. This study was conducted to determine the ion exchanges in Halocnemum strobilaceum and Halostachys caspica in saline conditions. The...
