“…Different responses between plant species are reported in the literature regarding pre-treatment in solutions to attenuate salt stress . Soaking increased the germination of Physalis angulata L. (Souza et al, 2016) and chia (Stefanello et al, 2019) seeds, and consequently their salt tolerance. Fredj et al (2013), when evaluating different soaking times (12, 24, and 36h) of coriander seeds in solutions prepared with different NaCl concentrations (0, 2, 4, 6, and 8g L -1 ), reported germination percentage above 90% up to the concentration of 4g L -1 , especially when the seeds were soaked for 12h.…”

Salinity is one of the striking problems in agricultural production in many parts of the world. Seed germination and seedling growth are two critical stages for the establishment of crops generally most sensitive to salt stress. The present study aimed at evaluating the germination and initial growth of pepper seedlings produced from seeds under different soaking times in NaCl solutions. The experiment was carried out in a completely randomized design, in a 2 × 4 × 5 factorial scheme using two pepper species (Capsicum chinense Jacq. and Capsicum frutescens L.), four levels of electrical conductivity (EC) of solutions (1.5, 3.0, 4.5, and 6.0 dS m-1) and five times of seed soaking in the solutions (2, 4, 6, 8 and 10 h), with three replications. The traits evaluated were the number of germinated seedlings, percentage of germination, seedling height, and root length. The results showed that C. frutescens pepper was more tolerant to different times of soaking in saline solutions prepared with NaCl compared to C. chinense. Thus, the results suggest that depending on the pepper species, it is recommended to use seeds primed in saline solutions with salinity levels compatible with those under field conditions (in saline soils and/or irrigation with saline waters).

“…When evaluating the influence of the salts NaCl, KCl, CaCl 2 and MgCl 2 on the seed germination of chia (Salvia hispanica L. -Lamiaceae), Stefanello et al (2020) concluded that CaCl 2 and MgCl 2 had a negative effect on germination and vigor of seeds when compared to NaCl and KCl. In other words, the chemical differences between these salts can cause changes in the results of germination and vigor of seeds, even when at similar osmotic potentials (Souza & Cardoso, 2000).…”

Mandacaru (Cereus jamacaru DC.) is a cactus widely found in the Caatinga, with its seeds usually subjected to adverse conditions. Therefore, the objective of this study was to evaluate the effect of water restriction on germination and vigor of mandacaru seeds by using different salts and osmotic potentials. To that end, we used saline solutions of NaCl, KCl, CaCl 2 and MgCl 2 prepared at the osmotic potentials of 0.0; -0.2; -0.4; -0.6; -0.8; -1.0 and -1.2 MPa. Four replicates of 50 seeds per treatment were used, distributed in "gerbox" boxes between blotter paper and under temperature of 25 °C. Counts of the number of germinated seeds were performed daily for 21 days after root protrusion. The variables analyzed were the following: water content (%), germination (%), mean germination time and normal seedlings (%). A completely randomized following the factorial scheme 4 × 7 (salts × osmotic potentials) was employed. Results obtained suggest that mandacaru seeds show the ability to germinate in saline soils, a characteristic found in arid and semi-arid areas. Decreased osmotic potential promoted reductions in germination (%) and vigor of Cereus jamacaru DC seeds. The MgCl 2 salt was the one that most negatively affected the germination and initial seedling development.

“…Literature results show that salinity harms the percentage of the physiological potential of various cultures, such as Oryza sativa L. (CAVALCANTE et al, 2019), Pisum sativum (PEREIRA et al, 2020), Vigna unguiculata L. (GOMES FILHO et al, 2019), and Salvia hispanica (STEFANELLO et al, 2020).…”

Saline stress is a condition that causes changes in physiological performance in several species and even in cultivars of the same species. Thus, this studyaimed to evaluate the physiological performance of black bean cultivars to salt stress. A completely randomized experimental design was used in a factorial scheme with two cultivars (Mataço and BRS Paisano) and five osmotic potentials simulated with sodium chloride solutions (control = 0.0; -0.2; -0.4; -0.6 and -0.8 MPa), in four replications of 50 seeds per treatment. The variables related to germination, first germination count, germination speed index, and shoot length were evaluated. There were significant interactions (p <0.05) for all variables analyzed. In general, it is concluded that the physiological performance of the seeds of black bean cultivars is affected under simulated saline stress by NaCl solution with an osmotic potential below -0.2 MPa.
