“…All our major crops and most wild species are relatively sensitive to environmental stress conditions such as drought or salinity, but tomato is moderately resistant to salt, withstanding a soil ECsat up to 6 dS m −1 , so that it can be cultivated in regions exposed to a certain degree of soil salinisation (Maggio et al, 2004). Yet high soil salinity inhibits seed germination and plant growth, and causes reduction in crop yields (Dalton et al, 1997;Romero-Aranda et al, 2002).…”

“…Responses to salinity in tomato, within its salt-tolerance range under natural conditions, have been extensively studied, but only few authors have analysed its responses to higher salt concentrations (Maggio et al, 2004). Subjecting the plants to 'shock treatments' at very high NaCl concentrations, well above those they encounter in the field, may trigger adaptation mechanisms that cannot be observed at low or moderate salinity levels.…”

The effects of salt and water stress on growth and several stress markers were investigated in cherry tomato plants. Some growth parameters (stem length and number of leaves) and chlorophyll contents were determined every third day during plant growth, and leaf material was collected after 25 and 33 days of treatment. Both stresses inhibited plant growth; chlorophyll levels, however, decreased only in response to high NaCl concentrations. Proline contents largely increased in leaves of stressed plants, reaching levels high enough to play a major role in cellular osmotic adjustment. Despite reports indicating that tomato does not synthesize glycine betaine, the stress-induced accumulation of this osmolyte was detected in cherry tomato, albeit at lower concentration than that of proline. Therefore, it appears that the plants are able to synthesise glycine betaine as a secondary osmolyte under strong stress conditions. Total sugars levels, on the contrary, decreased in stress-treated plants. Both stress treatments caused secondary oxidative stress in the plants, as indicated by a significant increase in malondialdehyde (MDA) contents. Water stress led to an increase in total phenolics and flavonoid contents and a reduction of carotenoid levels in the leaves; flavonoids also increased under high salinity conditions.

“…This may indicate that L. pennelliiderived salt tolerance involves the production of more roots as a strategy to absorb more water in soil with low osmotic potential. An increased root to shoot ratio has been reported to be associated with NaCl stress in tomato (Maggio et al 2004). The root to shoot ratio of M82 decreased by 2.2 and 2.5-fold for wet and dry mass, respectively, while that of LA716 increased by 2.5 and 3.5-fold, respectively.…”

The growth and ion content of salt sensitive Lycopersicon esculentum Mill. cv. M82 and salt tolerant L. pennellii Correll accession LA716 were examined under both control and stress conditions (150 mM NaCl). L. esculentum grew more vigorously than L. pennellii under optimal conditions, however, L. pennellii was able to maintain its growth better than cultivated tomato when the plants were exposed to salinity. Sodium content of both L. esculentum and L. pennellii increased as a result of NaCl stress. In addition, both species showed reduced potassium and calcium content due to salinity. The physiological traits were also measured in a population of 52 L. pennellii introgression lines grown under both normal and stress conditions. A total of 311 quantitative trait loci (QTL) were identified for the studied traits: plant height, stem diameter, leaf number, leaf and root fresh and dry mass, and sodium, potassium and calcium contents. Some of the loci (124) were identified under both control and stress conditions while 86 QTL were identified only under non-stress conditions and 101 loci were identified only under NaCl stress.

“…Therefore, methods or practices that increase water use efficiency, soil productivity and reduce the excessive amount of water applied are of importance for conserving water. The effect of the quality of irrigation water on soil properties has been discussed by many researchers [3][4][5][6][7][8][9][10][11][12][13]. Ragab [14] found that soil electrical conductivity (EC s ) values increased with increasing salinity of irrigation water and decreased soil moisture depletion in calcareous soil.…”

A field experiments were conducted for three growing seasons (2007 to 2009) at five different sites of soil types and salinity levels. Five different ground water qualities were used to irrigate five fields each with area of 50 to 54 hectares planted with wheat crop and the irrigation system used at each field was center pivot sprinkler system. The irrigated fields were located at different locations of Riyadh region in Saudi Arabia. The soil samples were taken at different depths (10, 20, 40, 60 cm) The quality effect of irrigation water on each soil salinity at each depth was determined. The results showed that all irrigated fields have differed in salt concentration as indicated by soil electrical conductivity (EC e ) values of the saturated paste extracts. The soil salinity in some fields decreased and increased in other soils, and the distribution of salts through the soil profile is highly correlated with the salinity of irrigation water and soil type. Saline water increased the soil salt content throughout the profile to a greater extent than nonsaline water. Thus, the salts accumulation in soil of field 4 and 5 was closely related to the salt concentration of irrigation water, and there was a progressive and significant increase in soil salinity values as the salinity of irrigation water increases. Also, the obtained results showed that the decrease or increase in soil salinity through the soil profiles for all fields occurred mainly at first season and slight increase in the following two seasons, and not with the increase of the number of seasons, and the soil salinity values remains closely the same and does not influenced by the prolonged use of low or high salinity waters for a number of years for all fields during the study.
