The foremost cause behind worldwide crop losses is attributed to abiotic stresses. Among them, salinity is a major concern for agriculture and is expected to play an increasingly important role as rising food demands and climate changes will inevitably lead to the greater use of marginal lands and poor-quality irrigation water. Tomato is a moderately salinity-sensitive crop which is widely used in the presence of poor-quality irrigation water without manifesting yield reduction. However, the excessive accumulation of salts can reduce photosynthetic efficiency, unbalance nutrient assimilation, reduce growth, and reduce product quality. This study was undertaken to explore the response of some varieties of Solanum lycopersicum that could be used as model systems to evaluate the performance of wild tomato ecotypes in future studies to identify genetic resources that respond adequately to climate change in the Mediterranean area. Tomato seedlings were raised in vitro on plates with sucrose-free agarized medium containing increasing concentrations of sea salt. The autotrophic conditions enabled a response resembling the plant's behavior in vivo. The obtained results identified an interesting variety that can be used as a model for modern cultivars and concentrations, from which the behavior of some Solanum spp. can be further investigated.
