“…Sahin et al [31] pointed out that the reason for the decrease in plant growth may be salinity toxicity and the reduced water uptake due to the elevation of the soil matrix and osmotic potential caused by salinity. Similarly, our findings showed that compared to the S2 treatment, the S6 treatment decreased the ET a and WUE from 28.7% to 44.7% and from 34.1% to 58.3% from 2021 to 2022 (Figure 8), consistent with the results reported by Li et al [33]. The downward trend of the FW and FW/DW with the increase in irrigation water salinity (Figure 6) indicated that the water content of plants treated with S6 was lower, further proving that the inhibitory effect of the S6 treatment on plant root water uptake was greater than that of the S2 treatment.…”

“…Hou et al [66] demonstrated that the smaller the fruit, the lower the osmotic and water potential, which could help it compete more effectively for water in cases where the ability of its roots to absorb water is impaired. Furthermore, smaller fruits were less sensitive to salinity than larger fruits [33,67].…”

“…For fruit quality, saline water irrigation was found to have the opposite effects, which significantly improved the contents of TSS, TS, TA, and VC in tomato fruits. That may be because in order to weaken the harmful osmotic effects of salt, tomato plants underwent osmotic regulation, inducing a decrease in fruit water concentration, which consequently led to a certain increase in TSS, TS, TA, and VC concentrations [33,62]. In this study, the maximum values of TSS and TS was obtained with the S6 treatment, while the threshold for irrigation water salinity of VC and TA was recommended to be 4 g L −1 (Tables 3 and 4).…”

“…Compared to either salinity or drought stress conditions alone, the increased negative effects of treatments where the two stress factors were applied together were reported by Ors et al [32] on plant growth, photosynthetic activity, nutrient element content, and chlorophyll amount in tomato seedlings. Li et al [33] indicated that stomatal regulation was more likely to result in lower stomatal conductance than the net photosynthetic rate under appropriate reduced irrigation when subjected to salinity stress. Yang et al [34] found that simultaneous water and salt stress aggravated a decline in yield, but mild drought at a certain salinity level can promote fruit osmotic adjustment, thereby improving tomato fruit quality.…”

Drought hardening could promote the development of plant roots, potentially improving the resistance of crops to other adversities. To investigate the response and resistance of physiological and growth characteristics induced by drought hardening to salt stress in the later stages, a greenhouse experiment was carried out from 2021 to 2022 with one blank control treatment and twelve treatments that comprised combinations of four irrigation regimes (W1 = 85%, W2 = 70%, W3 = 55%, and W4 = 40% of the field capacity) and three irrigation water salinity levels (S2, S4, and S6, referring to 2 g, 4 g, and 6 g of sodium chloride added to 1000 mL of tap water, respectively). The results show that saline water irrigation introduced a large amount of salt into the soil, resulting in the deterioration of tomato growth, physiology, yield, and water use efficiency (WUE), but had a positive, significant effect on fruit quality. When the irrigation water salinity was 2 g L−1, the W2 treatment could reduce soil salt accumulation, even at the end of the maturation stage; consequently, enhancing the increments in plant height and leaf area index during the whole growing stage. The physiological activity of tomato plants under the W2 and W3 treatments showed a promoting effect. Correspondingly, the maximum values of the fruit quality of tomato plants irrigated with the same saline water were all obtained with the W2 or W3 treatment. However, the yield and WUE of the W3 treatment were lower than that of the W2 treatment, which was the highest among the same saline water irrigation treatments, consistent with the reflection of the changing trend of the ratio of fresh weight to dry weight. Overall, drought hardening can be considered an economically viable approach to mitigate the hazards of saline water irrigation, and the W2S2 combination is recommended for tomato production due to the maximum values of yield and WUE with a higher fruit quality among the twelve saline water irrigation treatments.

“…The photosynthetic response is always adjusted by gs , resulting in a change in WUE when plants are exposed to osmotic stress. The salinity effect on WUE varies with the intensity and duration of stress [ 55 , 56 ]. WUE was improved under a certain stress range, but this improvement was dependent on the cultivar.…”

The olive tree (Olea europaea L.) is the main fruit tree in most of the arid and semi-arid regions of Tunisia, which is where the problem of salinity is more pronounced. Salinity is one of the main factors that affects the productivity of olive trees, so the objective of this experiment was to study the effects of salinity on the photosynthesis, water relations, mineral status, and enzymatic activity of two cultivars of Olea europaea L., ‘Chemlali’ and ‘Koroneiki’. The trial was conducted under controlled conditions in a greenhouse for a period of 49 days and included two treatments: T0 control and T100 (irrigation with 100 mM of NaCl solution). Under salinity stress, the photosynthesis, stomatal conductance, and leaves of both cultivars were negatively affected. ‘Chemlali’ showed greater tolerance to NaCl salinity, based on a progressive decrease in osmotic potential (Ψπ) followed by a progressive and synchronous decrease in gs, without a comparable decrease in photosynthesis. The water use efficiency (WUE) improved as a result. In addition, the K+/Na+ ratio in ‘Chemlali’ rose. This appears to be crucial for managing stress. Conversely, enzymatic activity showed an accumulation of glutathione peroxidase (GPX) in stressed plants. The catalase (CAT) and ascorbate peroxidase (APX) content decreased in both stressed varieties. It can be concluded that the cultivar ‘Koroneiki’ is more susceptible to salt stress than the cultivar ‘Chemlali’, because the accumulation of GPX and the decreases in CAT and APX were more pronounced in this cultivar.
