“…Cl -is the most prevalent anion under saline conditions. To prevent these problems, plants suppress the influx and accumulation of Na + in the cytoplasm, especially in leaves (Esmaili et al 2008, Patel andPandey 2008). We found that, in all tissues under salt stress, the Na + and Cl -contents increased dramatically in salt-sensitive cultivars.…”

“…Plants subjected to such environments, take up high amounts of Na + (Esmaili 2008), whereas the uptake of K + and Ca 2+ is considerably reduced (Patel and Pandey 2008). Reasonable amounts of both K + and Ca 2+ are required to maintain the integrity and functioning of cell membranes (Ashraf 2004).…”

“…Reasonable amounts of both K + and Ca 2+ are required to maintain the integrity and functioning of cell membranes (Ashraf 2004). In Agropyron spp., the high salt tolerance of A. elongatum relative to A. intermedium, is associated with its higher uptake of K + under saline conditions (Ashraf 2004, Afzal et al 2008, Patel and Pandey 2008. Researchers concluded that roots of the salt-tolerant Beta vulgaris had a greater affinity for K + relative to Na + than did the salt-sensitive Phaseolus vulgaris.…”

In this study, Na + , Cl -, K + , Ca 2+ , chlorophyll and proline levels and the rate of lipid peroxidation level in terms of malondialdehyde (MDA), were investigated in tissues of 15 different tomato cultivars in salt tolerance. As a material, 15 different tomato genotypes were used during a 28-day period and 150 mmol NaCl was applied in sand culture. While one of tomato genotypes was a wild type belonging to Lycopersicum peruvianum, the others were local genotypes belonging to Lycopersicum esculentum L. Better NaCl-stress tolerance in salt-tolerant cultivars as compared to salt-sensitive cultivars observed during the present investigation might be due to restriction of Na + accumulation and ability to maintain high K + /Na + ratio in tissue. The chlorophyll level decreased more in salt-sensitive than in salt-resistant cultivars, whereas proline level increased more in salt-sensitive than in salt-resistant cultivars. The exposure to NaCl induced a significant increase in MDA level in both salt-resistant and salt-sensitive cultivars; yet, MDA level was higher in salt-sensitive cultivars. As a result, exclusion or inclusion of Na + , Cl -, K + and Ca 2+ MDA levels, chlorophyll and proline levels may play a key protective role against stress and these features can be used as identifiers for tolerance to salt.

“…The main negative effects of high salinity that influence plant growth and development are photosynthesis inhibition (Sharma et al 2005), water deficit (Suárez and Medina 2008), ion toxicity associated with excessive Cl -and Na + (Afzal et al 2008, Patel andPandey 2008), interference with nutrition leading to nutrient imbalance (Misra et al 1997). Bastías et al (2004) have reported that high concentrations of salt disrupt homeostasis in water relations and change the ion distribution at both cellular and whole plant levels.…”

Two-year old seedlings of Silver buffaloberry (Shepherdia argentea (Pursh) Nutt.) were exposed to NaCl salinity (0, 200, 400 and 600 mmol/l) for 30 days. Leaf water potential (Ψ w ), chlorophyll contents (Chl a, b, and a + b) and K + content decreased with an increase in salinity. Relative water content (RWC) declined significantly with 400 and 600 mmol/l NaCl. However, salinity induced an excessive accumulation of Na + in the leaves of plants. Light responses of photosynthesis showed that net photosynthetic rate (P N ) values were continuously raised with the increase of photosynthetic photon flux density (PPFD) at all salinity levels and plants treated with 600 mmol/l salinity suffered from photoinhibition with the lowest P N values. The reduction of P N and stomatal conductance (g s ) associated with a sharp increase of intercellular CO 2 concentration (C i ) in the leaves at 600 mmol/l salt-treated plants showed that non-stomatal limitations might have prevailed over stomatal limitations under severe saline conditions, due to severe cellular dehydration, inhibited synthesis of chlorophyll and ionic imbalance and toxicity. It is concluded that S. argentea possesses high salt tolerance capacity and can be widely cultivated in salt-affected areas.

duced successfully on marginal lands, such as those affected by salinity, reduces the pressure to produce energy crops on land that would otherwise be used to produce food crops. In this paper, the degree of salinity tolerance of "Red River" prairie cordgrass (Spartina pectinata Link) and "Cave-in-Rock" switchgrass (Panicum virgatum L.) was determined by evaluating seed germination, plant growth, ion uptake, and leaf anatomical feature responses in saline conditions. Red River seeds retained 50% of germination potential under high salinity up to 300 mM NaCl, whereas Cave-in-Rock seed germination was reduced by 80% at 300 mM NaCl. Red River seedlings survived up to 500 mM NaCl, while more than 30% of Cave-in-Rock did not survive above 100 mM NaCl in greenhouse experiments. Red River produced more biomass and second-generation tillers and had a greater root and shoot biomass ratio than Cave-in-Rock under all salinity ranges. Sodium accumulation in shoots of Cave-in-Rock increased with increasing salinity, whereas Red River maintained a low level of sodium in biomass through salt-gland exclusion. The increasing rate of selectivity coefficient for potassium over sodium in Red River was higher than in Cave-in-Rock with increasing salinity. Although seed germination and plant growth decreased as salinity increased, Red River retained its potential of seed germination and to produce new tillers and biomass under salinity stress.
