Abstract	This study addresses the physiological response of four tomato genotypes with distinct sensitivity to high NaCl concentrations, with the aim of identifying physiological traits to rank the genotypes’ sensitivity to salt stress. The central hypothesis was that tomato genotypes grown in saline environments show a characteristic salinity-triggered absorption and translocation of ions, leading to a distinct distribution pattern of Na, K, and soluble sugars. Experiments were conducted on two commercial cultivars: one assumed to be sensitive (Solanum lycopersicum L. F1 hybrid Harzfeuer) and one known to be tolerant (S. lycopersicum L. var. edkawi) to high salt concentrations. Furthermore, two wild salt-tolerant relatives (S. pennellii and S. lycopersicum var. cerasiforme) were selected. Based on our results regarding vegetative performance and partitioning of Na, K, glucose, fructose, and sucrose, it is possible to classify the genotype S. lycopersicum F1 hybrid Harzfeuer as moderately sensitive to salt stress and the genotypes S. lycopersicum var. edkawi, S. lycopersicum var. cerasiforme, and S. pennellii as moderately resistant to 210 mM NaCl. Calculations of the percentage of modification revealed non-specific genotype responses for the amount of sodium in roots and leaves, as well as the sucrose concentration and the osmotic potential of leaves. As shown, the salt-induced changes in potassium levels in leaves, and glucose concentration in roots might be used as additional traits to discriminate genotypes regarding their salt-sensitivity. These parameters might be useful when comparisons of fruit production or vegetative performance provide no conclusive indication e.g. due to the distinct growth habits of commercial cultivars selected for fruit productivity and native genotypes having a stronger vegetative development. However, additional studies should be conducted to evaluate a large number of genotypes differing in their NaCl tolerance. Furthermore, plant responses considering the dynamic source-sink relations due to fruit load needs to be considered.
