Salinity is one of the major threats facing the cultivation of field crops. The response of six rice (Oryza sativus L.) cultivars to different sodium chloride levels; 0, 30, 60, 90, 120, and 150 mM were investigated during germination and early seedling stages. Germination percent, mean germination time (MGT), shoot and root length and dry weight were all decreased as the levels of NaCl used increased. Percent reduction in dry weight over control was increased as the NaCl levels increased. Forat and Amber 33 were more salt tolerant cultivars with regard to germination percent, while Hwazawi cultivar was more sensitive. Hwazawi cultivar recorded the lower MGT while Amber 33 cultivar showed the higher MGT. Length of radicle and plumule of all cultivars were differently affected by salt, as Hwazawi and Mushkab cultivars showed more reduction in length while Amber 33 was less affected. Forat cultivar dry weight was more affected by salt compare to other cultivars. The effect of NaCl on salt tolerance index of cultivars was significant. The ranges of salt tolerance indices among salt levels were very wide, ranging from 95.42 at 30 mM of NaCl to 71.38 at 150 mM of NaCl. Interaction between salt levels and cultivars showed varying degree of differences. It is concluded that the different cultivars differ in their salt tolerance with respect to seed germination and seedling growth.

“…The level of proline accumulation continued to rise even when promotion of growth was diminished. Similarly, Zhao et al (2009) found that different salt applications increased proline levels in mangrove Thellungiella halophila. Soluble sugar also imparts osmotic regulation of the cell under salt stress (Figure 3).…”

Different techniques have been suggested to protect plants from environmental stress. Therefore, new techniques should be developed to produce salt-resistant genotypes. Selection and improvement of desirable genotypes for this objective require suitable screening methods. Tissue culture can help in the efforts to produce new cultivars against environmental stress factors. In addition, in vitro culture studies permit relatively faster responses, shorter generation time, and regular environmental conditions as compared to classical breeding methods (Zhao et al., 2009;Elmaghrabi et al., 2013). A high level of salt in soil or in tissue culture may lead to numerous genetic and biochemical changes, causing problems such as limitation in mineral nutrient uptake, nutritional imbalance, mineral deficiency, osmotic stress, ion toxicity, and oxidative stress (Rozema and Flower, 2008;Rahnama et al., 2010;James et al., 2011). It has been reported that oxidative and osmotic stresses affect the cellular membrane integrity, enzyme activity, DNA, and chlorophyll content (Lokhande et al., 2010), which inhibits the functioning of most plant species.Proline is the most common metabolite that accumulates in response to salinity stress, shown to serve as a main osmotic regulator, and was reported in various plant species (Koca et al., 2007). The role of proline accumulation in plants' osmotic regulation is still unclear (Koskeroglu and Tuna, 2010). Soluble sugar is known to commonly accumulate in higher plants against salinity stress, which could play a role in osmotic protection (Khedr, 2003). Salt stress usually inhibits the plant growth. When plants are exposed to different abiotic stresses, some reactive oxygen species (ROS) removing enzymes such as superoxide dismutase (SOD), peroxidase (POD), ascorbate peroxidase (APX), and catalase (CAT) are produced (Li and Staden, 1998). The antioxidant enzyme activity is positively associated with salt tolerance in plants (Lokhande et al., 2011). Many researchers have indicated that the salt resistance mechanism is activated during the entire plant stage and this has been tested in both in vitro and ex vitro situations (Watanabe et al., 2000; Troncoso et al., 2002). A close relationship between physiological changes and callus cultures by salt stress has been previously reported in different genotypes (Piwowarczyk et al., 2016).

“…Other investigators have reported the use of NaCl for in vitro salinity screening in other species of plants (Vijayan et al 2003;Zhao et al 2009), but the concentrations used have not been as high as those used in this study. All growth and physiological parameters were significantly affected by salt stress.…”

Salinity stress is a major abiotic stress for plants worldwide. This study was carried out to determine the variation in salt tolerance for 12 different genotypes belonging to three different tomato species: Solanum lycopersicum (L), S. peruvianum (L) and S. pimpinellifolium (L). Shoot apices and callus cultures were exposed to different levels of salinity stress ranging from no salt (control) to 100, 200 and 300 mmol L −1 NaCl. All growth and physiological parameters were significantly affected by salt stress. Most shoot apices of S. lycopersicum did not develop roots when exposed to low NaCl levels, whereas apices of S. peruvianum and S. pimpinellifolium developed roots when exposed to all salt levels. This difference in salt tolerance was clearly shown on the basis of root fresh weights and root surface areas. Callus growth in response to increased salinity was much greater in S. peruvianum and S. pimpinellifolium than in S. lycopersicum. The Cl − and Na + concentrations increased significantly with increasing salt in the three species, although the S. peruvianum lines accumulated more ions compared with the others. As the salt concentration increased, less K + accumulated in S. lycopersicum compared to the related wild species. The results obtained in this study suggest that S. peruvianum line 0043-1 was the accession with the best salt tolerance. The most tolerant cultivated tomato (S. lycopersicum) cultivar was 'Rutgers. ' Both S. peruvianum line 0043-1 and S. lycopersicum 'Rutgers' are good candidates for inclusion in tomato breeding programs for salt-tolerance.
