“…One of the biggest issues in the agriculture sector is salt stress which reduces plant growth as indicated previously and in the present study [5,12,25,41]. Salt stress limits plant growth by interfering with various physiological processes and molecular alterations, i.e., photosynthesis, ionic imbalance, and increasing ROS buildup [7,8,11].…”

“…Salinity induces a series of morpho-physiological responses and molecular modifications that prevent plant development and flowering behavior [5][6][7][8][9]. Salinity injury in plants is primarily caused by osmotic stress, cytotoxicity, and nutritional conflict [5][6][7][8][9]. Salinity reduces a plant's ability to absorb enough water to meet its evaporative demands, causing growth and flowering decline and lessened metabolic pathways [8,[10][11][12].…”

Petunia (Petunia × hybrida Hort. Vilm.-Andr.) is a well-suited plant for sustainable landscape issues in borderline areas with irrigation with saline water. Salicylic acid (SA) as a modulator performs an imperative function in modulating plant salt tolerance. However, there are a few reports on the effect of SA on petunia plants irrigated with saline water. During the 2022/2023 season, a factorial pot experiment in a randomized complete block design was carried out in Riyadh, Saudi Arabia, to assess the effect of SA concentration (0, 500, 1000, 2000 mgL−1) on petunia plant growth, flowering, ion content, chlorophyll level, and proline concentration under irrigation with salty water (230, 1500, 3000 mgL−1). Saline water up to 3000 mgL−1 dramatically reduced plant growth, chlorophyll, ions, and flowering attributes, while the contrary was observed in proline and sodium concentrations as compared to the control treatments (irrigation with tap water). Foliar spraying with 1000 mgL−1 SA considerably boosted plant growth and flowering as well as chlorophyll, proline, and ion content compared to untreated plants under such salinity levels. Alternatively, the application of 1000 mgL−1 to normal or salinized water significantly decreased the Na content in non-treated plants under such a salinity level. Accordingly, using 1000 mgL−1 of SA under salt stress conditions could be a useful technique to lessen the mutilation induced by the use of salinized water in the era of climate change.

“…Consequently, it is difficult for existing freshwater resources to meet the water needs of agriculture, a traditional large-scale water-using industry, forcing attention to turn to opening up new available water sources, i.e., saline water, which is rich in reserves and easy to exploit and utilize. However, while saline water irrigation replenishes the soil with water, it also carries a large amount of salt into the soil [3]. Thus, a series of problems caused by a massive accumulation of soil salt at a fast speed occurs, such as soil salinization, plant physiological drought, ion toxicity, and micropopulation decline, decreasing crop yield and quality [4][5][6][7].…”

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.
