“…These results are consistent with Zhang et al [16], who reported that adding an amount of salt to the nutrient solution improves the quality of tomato fruits. The same was reported by Helaly et al [19], who reported that irrigating tomatoes with saline water resulted in a significant increase in total soluble solids and improved fruit quality, compared to the control. Although total tomato fruit production decreased with increasing irrigation water salinity, internal quality, characterized by taste and health-promoting compounds, such as total soluble solids and organic acids in tomato fruits, can be improved [18].…”

“…Also, Zaki et al [17] reported that increasing salinity levels gradually decreased average tomato fruit weight. Helaly et al [19] stated that irrigating tomatoes with saline water resulted in a decreased fruit yield, compared to the control. In general, increasing salt concentration in the nutrient solution led to a decrease in fruit yield.…”

To overcome the scarcity of fresh water, researchers have turned to investigating different techniques that enable using saline water to irrigate crops, aiming to increase the efficiency of using available water resources. A glasshouse experiment was conducted to investigate the yield responses of grafted and non-grafted (self-rooted) tomato plants grown hydroponically under three levels of water salinity (2.5, 6.0, and 9.5 dS m−1). Three tomato varieties (Ghandowra-F1, Forester-F1, and Feisty-Red) were grafted onto five rootstocks (Maxifort, Unifort, Dynafort, Vivifort, and Beaufort). The implemented treatments were studied in terms of tomato fruit yield and quality parameters. Although increasing the concentration of salts in the nutrient solution led to a decrease in fruit yield, the moderate salinity level (S-2: 6.0 dS m−1) showed its superiority over both low salinity (S-1: 2.5 dS m−1) and high salinity (S-3: 9.5 dS m−1) in terms of tomato yield parameters. The studied rootstocks did not significantly improve the tomato fruit yield, but the interaction between the grafting combinations and salinity was significant for both production and quality. More specifically, tomato plants grafted onto the rootstocks “Vivifort and Beaufort” rendered the highest yield at a low salinity level (S-1: 2.5 dS m−1) and a moderate salinity level (S-2: 6.0 dS m−1), respectively, while at high salinity (S-3: 9.5 dS m−1), grafting did not improve tomato productivity, irrespective of the rootstock. These results confirm that tomatoes can be successfully grown under hydroponic systems using salinity levels of up to 6.0 dS m−1 without sacrificing fruit yield and quality. Among the studied tomato varieties, Feisty-Red was found to be appropriate for hydroponic production. The results also demonstrated that Vivifort and Beaufort rootstocks are suitable for grafting hydroponic tomatoes under low and moderate salinity levels, respectively.

“…In contrast, the other genotypes did not change their fruit number under salinity stress conditions (Table 1). This decline in fruit number can be attributed to the disruption of the plant's physiological functions caused by osmotic stress and the consequent imbalance of nutrients resulting from the increased concentration of salt [38]. Therefore, our results indicate that the decline in production was primarily driven by a decrease in the average fresh fruit weight and the number of fruits per plant [39], and this effect was genotype-dependent.…”

Salinity is a major stress factor that compromises vegetable production in semi-arid climates such as the Mediterranean. The accumulation of salts in the soil can be attributed to limited water availability, which can be exacerbated by changes in rainfall patterns and rising temperatures. These factors can alter soil moisture levels and evaporation rates, ultimately leading to an increase in soil salinity, and, concomitantly, the extent to which crop yield is affected by salinity stress is considered cultivar-dependent. In contrast to tomato hybrids, tomato landraces often exhibit greater genetic diversity and resilience to environmental stresses, constituting valuable resources for breeding programs seeking to introduce new tolerance mechanisms. Therefore, in the present study, we investigated the effects of mild salinity stress on the growth, yield, and nutritional status of sixteen Mediterranean tomato landraces of all size types that had been pre-selected as salinity tolerant in previous screening trials. The experiment was carried out in the greenhouse facilities of the Laboratory of Vegetable Production at the Agricultural University of Athens. To induce salinity stress, plants were grown hydroponically and irrigated with a nutrient solution containing NaCl at a concentration that could maintain the NaCl level in the root zone at 30 mM, while the non-salt-treated plants were irrigated with a nutrient solution containing 0.5 mM NaCl. Various plant growth parameters, including dry matter content and fruit yield (measured by the number and weight of fruits per plant), were evaluated to assess the impact of salinity stress. In addition, the nutritional status of the plants was assessed by determining the concentrations of macro- and micronutrients in the leaves, roots, and fruit of the plants. The key results of this study reveal that cherry-type tomato landraces exhibit the highest tolerance to salinity stress, as the landraces ‘Cherry-INRAE (1)’, ‘Cherry-INRAE (3)’, and ‘Cherry-INRAE (4)’ did not experience a decrease in yield when exposed to salinity stress. However, larger landraces such as ‘de Ramellet’ also exhibit mechanisms conferring tolerance to salinity, as their yield was not compromised by the stress applied. The identified tolerant and resistant varieties could potentially be used in breeding programs to develop new varieties and hybrids that are better adapted to salinity-affected environments. The identification and utilization of tomato varieties that are adapted to salinity stress is an important strategy for promoting agriculture sustainability, particularly in semi-arid regions where salinity stress is a major challenge.

“…11,12 Consequently, salinity-induced challenges remain a central concern for global tomato cultivation and fruit quality. It was reported that although tomato fruit yield productivity decreased with saline water irrigation, fruit quality increased based on the increased concentrations of β-carotene, lycopene, and vitamin C. 13 Yet, research on amino acids and many other important phytochemicals, including carotenoids, and specific polyphenols like flavonoids, flavanones, and flavones, remains limited for tomatoes. 14−16 Targeted and untargeted metabolite analysis has been applied to understand variations during different growth stages, plant's metabolic response to environmental contaminants, the impacts of soil types, and the effect of abiotic and biotic stresses.…”

In this study, we evaluated the effect of increasing the salinity of irrigation water on the metabolic content and profiles of two tomato cultivars ('Jaune Flamme' (JF) and 'Red Pear' (RP)) using targeted and untargeted metabolomics approaches. Irrigation of tomato plants was performed with four different salt concentrations provided by chloride (treatment 1) and sulfate (treatment 2) salts. Targeted analysis of the methanolic extract resulted in the identification of nine major polyphenols. Among them, chlorogenic acid, rutin, and naringenin were the prominent compounds in both cultivars. In addition, the quantification of 18 free amino acids from both tomato cultivars showed that different salinity treatments significantly enhanced the levels of glutamine, glutamic acid, and γ-aminobutyric acid (GABA). Using the untargeted metabolomic approach, we identified 129 putative metabolites encompassing a diverse array of phytochemicals including polyphenols, organic acids, lipids, sugars, and amino acids. Principal component analysis (PCA) of mass spectral data acquired under positive and negative ionization modes showed a clear separation between the two cultivars. However, only positive ionization showed separation among different salinity treatments. Unsupervised and supervised learning algorithms were applied to mine the generated data and to pinpoint metabolites different from the two cultivars. These findings suggest that different salinity conditions significantly influenced the accumulation of phytochemicals in tomato cultivars. This study will help tomato breeding programs to develop value-added tomato cultivars under varying environmental conditions.
