“…The tomato (Lycopersicon esculentum Mill.) the salt-sensitive cultivar, "Ailsa Craig" [99] was used in the present study. Seeds were collected from the Laboratory of Protected Horticulture, College of Horticulture, Nanjing Agricultural University, Nanjing, China and surfaced sterilized with 10% Sodium hypochlorite solution (NaClO), rinsed five times with deionized dd H 2 O (double distilled water) and incubated at 28 • C in Petri dishes under dark conditions until the emergence of the radicle.…”

Salinity is a ubiquitous stressor, depleting osmotic potential and affecting the tomato seedlings’ development and productivity. Considering this critical concern, we explored the salinity response in tomato seedlings by evaluating them under progressive salt stress duration (0, 3, 6, and 12 days). Intriguingly, besides the adverse effect of salt stress on tomato growth the findings exhibited a significant role of tomato antioxidative system, RBOH genes, ABA biosynthesis, and signaling transcription factor for establishing tolerance to salinity stress. For instance, the activities of enzymatic and non-enzymatic antioxidants continued to incline positively with the increased levels of reactive oxygen species (O2•−, H2O2), MDA, and cellular damage, suggesting the scavenging capacity of tomato seedlings against salt stress. Notably, the RBOH transcription factors activated the hydrogen peroxide-mediated signalling pathway that induced the detoxification mechanisms in tomato seedlings. Consequently, the increased gene expression of antioxidant enzymes and the corresponding ratio of non-enzymatic antioxidants AsA-GSH suggested the modulation of antioxidants to survive the salt-induced oxidative stress. In addition, the endogenous ABA level was enhanced under salinity stress, indicating higher ABA biosynthesis and signalling gene expression. Subsequently, the upregulated transcript abundance of ABA biosynthesis and signalling-related genes suggested the ABA-mediated capacity of tomato seedlings to regulate homeostasis under salt stress. The current findings have revealed fascinating responses of the tomato to survive the salt stress periods, in order to improve the abiotic stress tolerance in tomato.

“…However, some cultivars still indicated higher growth under salt stress conditions (Fariduddin et al, 2012). The low salinity conditions stimulated plant growth and the accumulation of salts in the cell walls of some tomato cultivars (Kadoglidou et al, 2021).…”

“…The capacity of tolerance to salt stress ranges differently among the genotypes of tomatoes (Oliveira et al, 2022). It is possible to identify the most tolerant tomato genotypes to the effects of salinity based on the critical plant stage of cultivation (Kadoglidou et al, 2021).…”

The use of water with different salinity values in the production of vegetable seedlings is an issue of global concern; therefore, selecting tomato cultivars with tolerance to saline water is essential to improve the fruit quality and production. This study aimed to estimate the maximum electrical conductivity of irrigation water that does not harm the production of tomato seedlings and find cultivars with tolerance to the effects of salinity in this phase. In the first experiment, the treatments were arranged in a 3 × 8 factorial scheme (three tomato cultivars and eight values of electrical conductivity of irrigation water). The second experiment was arranged in a 10 × 3 factorial scheme (10 cultivars and three values of electrical conductivity of irrigation water). The 50% reduction in the root dry matter accumulation occurred with the electrical conductivity of irrigation water (ECw) of 2.31 dS m-1. The reduction of more than 50% of the Dickson quality index was observed with an ECw of 6.38 dS m-1. Irrigation with 3.0 dS m-1 impairs the complete emergence and growth of seedlings of all tomato cultivars. Coração de Boi, Dominador, Maestrina, Sheena, and Shanty were the tomato cultivars most tolerant to the irrigation water with 3.0 dS m-1 of ECw. The electrical conductivity of irrigation water higher than 2.31 dS m-1 impairs the root growth of tomato seedlings.

“…Kayess et al (2020) also observed a decrease in shoot fresh weight with a rise in salinity level. Kadoglidou et al (2021) observed a significant reduction in shoot fresh weight and shoot dry matter content under salt stress. Roots play an essential role in plant growth and development.…”

Salinity consists of critical abiotic stress adversely affecting tomato growth and development. Given the increase in saline areas, breeders endeavor to develop crops that can tolerate salinity. It indicates the importance of genotypes that can grow in salt-affected soil to cope with the problem. This study focused on identifying salt-tolerant and salt-sensitive genotypes using Principal Component Analysis (PCA). This study used a two-factor factorial under a complete randomized design, with three replications and three levels (T0 = control, T1 = 6 dS/m, T2 = 12 dS/m) of salt (NaCl) treatment. Data collection ensued at the seedling stage. Data for various morphological and biochemical attributes were recorded and subjected to analysis of variance and PCA to check the variation in germplasm and identification of suitable genotypes. Analysis of variance showed significant results for all attributes indicating the presence of variability in germplasm. Using PCA identified tolerant and non-tolerant tomato genotypes. Based on the results obtained from PCA analysis, genotypes AUT-318, CLN-2498A, 17884, Picendanto, 17260, 17256, 17263, and 17266 showed as salt tolerant, whereas the 19903, 19908, Target-66, H-24, 17255, Nadir, and Peelo displayed as salt-sensitive genotypes. Selected genotypes suit further use for the development of breeding material.
