“…In addition, Bernstein et al (1974) reported that yield reduced by 50% under saline soil(8 ds m -1 ). Similar results were obtained by Nukaya et al (1979) who reported that tomato was irrigated with saline water (50 -3000 ppm) the yield reduced by 47%. Rajasekaran and Shanmugavelu (1981) and Mondal (1983) reported reduction in tomato yield that was grown under irrigation with saline water ranged from 2.8 to 10.2 ds m -1 , the reduction ranged from 5 to 40%.…”

This study aimed to investigate the adaptation and selection of Castle Rock (fresh market tomato cv) for salinity tolerance. Also, to study the initial assessment of epigenetic variation under the salinity stress and taking advantage of these variations to adapt and select new tolerant line of Castle Rock. The study took about 6 years from 2005 to 2010. Adaptation and selection was conducted for the characteristics, plant height, main stem diameter, number of branches per plant, number of leaves per plant, leaf area, dry matters weight per plant, fruit setting, number of days to 50% flowering, number of days to fruit ripening, number of fruits per plant, average fruit weight, total yield per plant, total chlorophyll content, total soluble solids, titrated acidity, vitamin C content, seed germination, proline content, Ca ++ , K + and Na + content. As well as, anatomy was done for the main stem examining the percentage in measure between the stem diameter and pith, cortex and xylem. Three tomato genotypes were under the trial, Castle Rock (salinity sensitive cv), Edkawy (salinity tolerance cv) and C 9 (Castle Rock adapted selected new line). C 9 proved tolerant to salinity through adaptation in 9 selecting cycles and it can be reproduced as a new Castle Rock improved line for salinity tolerance.

“…In the present work, plants usually were shorter at the higher salt concentrations, but some authors say that plant growth may increase slightly following treatment with low concentrations of NaCl (Nukaya et al,, 1979;Shannon et al, 1987).…”

Plant height; stem thickness; fresh and dry weights of leaves and stems; numbers of leaves, trusses, flowers, and fruits; and leaf concentrations of Cl, Na, N-NO3, K, Ca, and Mg were measured in mature plants from 39 tomato accessions representing five species of Lycopersicon [L. esculentum Mill., L. peruvianum (L.) Mill., L. pimpinellifoliurn (Jusl.) Mill., L. hirsutum H. & B., L. pennellii (Corr.) D'Arcy] in response to various NaCl concentrations. Plants were irrigated with a nutrient solution, plus one of four levels of NaCl with electrical conductivities of 0.28, 0.63, 1.39, and 2.15 S·m-1. Characters were evaluated for each genotype taking into consideration: 1) the significant differences between NaCl concentrations, 2) the experimental errors in the analyses of variance, and 3) the uniformity of response to the salt concentrations. The characters that fulfilled these criteria for all 39 genotypes were: plant height, dry weights of leaves, fresh and dry weights of stems, and leaf concentrations of Cl and Na. However, other characters, although not generally applicable to the entire data set, were good indicators of response differences within a particular species. Leaf concentrations of N-NO3 and Mg were useful indicators in L. pimpinellifolium and L. esculentum and number of leaves and leaf concentration of Mg were useful indicators in L. hirsutum for responses of mature plants to salt stress.

SummaryGreen soybeans (Glycine max. Merr.) were grown in sand to determine the salt tolerance affected by salinization of sea water, NaCI, Na2504, MgC12 and Mg5O4 at osmotic potentials of -1.20, -1.70 and -2.70 bars as compared to a control of -0.70 bars of base nutrient solution. Dry weight of the whole plant, fresh weight of seeds and pods, and number of pole were greatest in the control and decreased in each salinity with decreasing osmotic potentials. Growth was greatest in the Mg504 series, less in the sea water and Na2SO4 series, and least in the NaCI and MgC12 series. There was a marked suppression of growth in the NaCI and MgC12 series at -2.70 bars. Chloride-salinity caused markedly different symptoms from those caused bysulfate-salinity. In chloride-salinity treatments chlorosis and necrosis were observed on margins of leaves, and developed acropetally at the middle and late stages of growth. The lower the osmotic potentials the more pronounced the symptoms. In sulfate-salinity treatments at only -1.70 bars interveinal chlorosis was found. Na, Mg, C1 and SO4 content of leaves and sand solution (SS) tended to increase with decreasing osmotic potentials of treatment solutions in sodium-, magnesium-, chlo ride-and sulfate-salinities, respectively. EC values of SS increased and osmotic potentials of SS decreased as osmotic potentials of treatmentsolutions decreased. The values were similar at the isosmotic potential in each salinity.
