“…Stefanello, Neves, Abbad, and Viana (2015), also researching S. hispanica seeds, observed that germination and vigor were compromised by an increase in the concentration of salts. Similar results were found in broccoli seeds by Lopes et al (2014); in tomato seeds by Silva Júnior et al (2014); in beet seeds by Bernardes, Mengarda, Lopes, Nogueira, and Rodrigues (2015); and in cabbage by Oliveira et al (2015).…”

“…Under high temperature conditions, there is an increase in seed metabolism, leading to greater soaking during the germination process. Thus, due to the high concentrations of salts present in the water and in the substrate, the absorption of the saline solution caused the seedlings to have inadequate supplies of nutrients because of the ionic imbalance resulting from excess Na + and Clions (Munns & Tester, 2008;Taiz & Zaiger, 2013;Lopes, Nascimento, Barbosa, & Costa, 2014).…”

Most plant species are susceptible to the effects of salinity, such as increases in osmotic potentials and deleterious ionic effects, which in turn affect water absorption in plants and, consequently, compromise germination and seedling growth. Hence, this study aimed to evaluate the effects of salinity on the germination, initial growth, and physiological and biochemical components of S. hispanica seedlings at different temperatures. The experimental design was completely randomized, with treatments distributed in a 5 x 4 factorial scheme with five saline concentrations (0.0 (control), 4.5, 9.0, 13.5, and 18.0 dS m-1) four temperature regimes (20, 25, 30, and 20-30°C), and four replicates of 50 seeds per treatment. The experiment evaluated the germination, growth, biochemical components (chlorophyll a, chlorophyll b, total carotenoids, amino acids, proline and sugars) and phytomass accumulation of S. hispanica seedlings. Saline levels higher than 4.5 dS m-1 together with treatment temperatures of 30 or 20-30°C negatively affected the germination, vigor, growth and biochemical components of the seedlings. The 25°C treatment temperature promoted the best conditions for the development of S. hispanica seedlings up to the saline level of 9.0 dS m-1 .

“…In addition, the increase in the concentration of NaCl ions causes toxicity to plants and may cause damages to the radicle, thus limiting the seed imbibition process and the absorption of water by the plantlet (Munns and Tester, 2008;Voigt et al, 2009;Taiz and Zaiger, 2013). Similar results were observed in other vegetables such as melon (Secco et al, 2010), broccoli (Lopes et al, 2014), beet (Oliveira et al, 2015a) and cabbage (Oliveira et al, 2015b).…”

This study aimed to evaluate the initial growth and tolerance of eggplant cultivars under saline water irrigation. The experiment was carried out in protected environment (greenhouse) at the Federal University of Campina Grande-UFCG, located in the municipality of Pombal-PB, Brazil. The experiment was set in a completely randomized design, in a 2 × 5 factorial scheme, corresponding to two eggplant cultivars (C 1-'Comprida Roxa' and C 2-'Preta Comprida/Enbu') and five levels of irrigation water salinity (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1), with four replication and five plants per replication. Plants were grown for 30 days on trays with 30 cells, with capacity for 0.1 dm 3 of substrate, monitored in relation to emergence, growth and phytomass accumulation, and evaluated with respect to the salinity tolerance index. Emergence, growth and dry matter accumulation of eggplant cultivars were negatively affected by the increase in irrigation water salinity. The cultivar 'Comprida Roxa' showed higher tolerance to irrigation water salinity in comparison to 'Preta Comprida/Enbu'.

“…A high concentration of salts is a stress factor for plants because water is osmotically retained in the salt solution. Therefore, the increase in salt concentration makes water less available to plants (Lopes et al, 2014). Species can adapt to salinity, but when they are sown in salt substrates, there is first a decrease in water uptake, which consequently reduces the speed of their physiological and biochemical processes.…”

The aim of this study was to evaluate seed physiological quality and initial pea (Pisum sativum) seedling development at different water and salt potentials. Polyethylene glycol 6000, sodium chloride and potassium chloride solutions with different osmotic potentials (0; -0.2; -0.4; -0.6; -0.8; -1.0, and -1.2 MPa) were used, and the experiment had a 3 × 7 factorial arrangement. The physiological quality and initial seedling growth characteristics (first germination count, final germination count, strong normal seedlings, epicotyl and taproot lengths, epicotyl dry matter, and root dry matter) were evaluated in a completely randomized experimental design, with four repetitions. Decreases in the observed variables showed that the simulated stress conditions negatively affected physiological performance, germination and initial seedling growth. The water and salt stresses induced by the sodium chloride and potassium chloride solutions were greater than the stress induced by polyethylene glycol 6000.
