“…In contrast to the effect of Cl À on NO À 3 uptake, others have reported that increased NO À 3 in the substrate decreased Cl À uptake and accumulation in numerous annual horticultural crops (Bernstein et al, 1974;Kafkafi et al, 1982;Feigin et al, 1987;Martinez and Cerda Â, 1989). This effect is particularly relevant in tree or vine crops that are prone to Cl-toxicity.…”

“…This is not surprising since an increase in Cl À uptake and accumulation is often accompanied by a decrease in shoot-NO À 3 concentration. Examples of such an effect have been found in cucumber, Cucumis sativus L. (Martinez and Cerda Â, 1989), eggplant, Solanum melongena L. (Savvas and Lenz, 1996), melon, Cucumis melo L. (Feigin et al, 1987), and tomato (Kafkafi et al, 1982;Feigin et al, 1987;Martinez and Cerda Â, 1989). Many attributed this reduction to Cl À antagonism of NO À 3 uptake (Bar et al, 1997;Feigin et al, 1987;Kafkafi et al, 1982) while others attributed the response to salinity's effect on reduced water uptake (Lea-Cox and Syvertsen, 1993).…”

“…Nitrogen deficiency is a growth limiting factor for plants (Tuncay et al, 2011). In cases of natural salinity, Na is often accompanied by chloride, which competes with nitrate (Kafkafi et al, 1982). However, high chloride content in water may reduce the absorption of nitrates and reduce their accumulation in leaves (Miceli et al, 2003).…”

This study was carried out to investigate the effects of irrigating lettuce (Lactuca sativa L. cv. Funly) with different concentrations of diluted seawater (0%, 2.5%, 5%, 10%, 15%, 20%) on the fresh yield, marketable yield and quality (DM, total soluble solids, titratable acidity, total sugar, vitamin C, NO3-N, protein, and total oxalate content). The experiments were conducted in a greenhouse in the autumn of 2012. The fresh yield, marketable yield, and DM of lettuce irrigated with 2.5% and 5% seawater were similar to those of control, but these parameters decreased in response to 10% seawater, and the lowest values were obtained in response to 20% seawater. The 2.5% seawater treatment had no effect on the vitamin C and NO3-N content, but both significantly decreased when lettuce was irrigated with seawater concentrations higher than 2.5%. Total soluble solids, total sugar, and protein content significantly increased in response to low salinity (2.5% and 5%) but decreased in response to increasing seawater stress. The titratable acidity values remained unchanged under the various saline conditions. Irrigation with diluted seawater did not affect the total oxalate content up to a concentration of 5%, but increasing the concentration of seawater above 5% increased oxalate content. The results of this study demonstrated that low concentrations of seawater are suitable for lettuce production and lettuce can be grown successfully using diluted seawater at concentrations of 2.5% and 5%.

“…This is not surprising, since with few exceptions (Feigin, 1985), an increase in Cluptake and accumulation is accompanied by a decrease in shoot nitrogen concentration. Example of this effect are also found in barley (Aslam et al, 1984), cotton (Silberbush and Ben-Asher, 1987), cucumber (Martinez et al, 1994), eggplant (Savvas and Lenz, 1996), tomato (Kafkafi et al, 1982), tomato and melon (Feigin et al, 1987) and wheat (Balasubramanian and Sarin, 1975). This study provides evidence that the salt stress reduces the nitrate assimilation capacity in all the sesame varieties, but the percentage of reduction varied.…”

In the present investigation a pot culture experiment was conducted in order to estimate the effects of salt stress on some physiological traits in seven sesame varieties like PAIYUR-1, SVPR-1, TMV-3, TMV-4, TMV-5, VIR-1 and VIR-2. Young and fully matured leaves were taken from control and salinity treated plants on 15th Days After Treatment (DAT), 30th (DAT) and 45th (DAT) for all the experiments in different salinity (NaCl) concentrations of control, 40mM, 80mM, 120mM.During the experiments of photosynthetic enzymes, foliar nitrogen and ABA content were measured. Lower rate of decreased photosynthesis, photosynthetic enzymes activity, foliar nitrogen and ABA content was increased with increasing salinity level in leaves of all the seven sesame varieties on all the sampling days. On 45th DAT, significantly higher enhancement of photosynthetic enzymes activity, foliar nitrogen, ABA content was observed in TMV-3 with 120mM salinity by relative to control plants while lower enhancement was noticed in PAIYUR-1 with 120mM salinity by compared to control plants. Moderate enhancement of photosynthetic enzymes, foliar nitrogen, ABA content was monitored in the variety VIR-2 with 120mM salinity on 45th DAT compared to control plants. TMV-3 exhibited higher adaptive potential under salinity stress as judged by increased photosynthetic rate and activities of photosynthetic, foliar nitrogen, higher accumulation ABA when compared to variety TMV-4 and PAIYUR-1 was closely followed by VIR-1. Variety VIR-2 was followed by SVPR-1 and TMV-5.
