“…Inversely, this correlation was weak with VC and IGD. Similar results were obtained with R. graveolens (Mguis et al, 2011;Barichello et al, 2021) and R. chalepensis (Hamdini et al 2021), which seem more tolerant to NaCl than R. montana since their thresholds of NaCl tolerance are 200 and 273.7 mM, respectively. The sensitivity of plants to salinity at the germination stage is also highlighted in the majority of plants, but with a more pronounced tolerance in halophytes compared to glycophytes (Qadir et al, 2008).This is the case, for example, of some species of the Atriplex genus (Bouda, Haddioui, 2011), Suaeda aralocaspica (Bunge) Freitag & Schütze (Wanget al, 2017), Marrubium vulgare L. (Nedjimi et al, 2020), and Lavandula stoechas L. .…”

This work is part of the exsitu conservation of Ruta montana (L.) L., a spontaneous Rutaceae, known for its many therapeutic properties. The aim is to study, under controlled conditions, the effects of daylight and darkness, temperature, salt, and water stress on the germination of its seeds. Salt stress was induced by different molar concentrations of NaCl (0–200 mM), and water stress was simulated using different concentrations of polyethylene glycol (PEG6000) corresponding to different water potentials (0-1.2 MPa). The results obtained showed that R. montana seeds were viable and could germinate both in daylight and in continuous darkness. Germination was possible at temperatures between 10 and 30 °C, with the maximum final germination percentage (FGP = 81.66%) recorded at 20 °C. At this optimum temperature, FGP decreased significantly when the seeds were placed under salt and water stress (p< 0.01).This decrease became more and more significant when the osmotic pressure induced by NaCl increased and when the water potential induced by PEG6000 in the medium decreased. The depressive effect of salt and water stress on FGP was verified by a linear regression analysis, which showed high values of the coefficient of determination (R 2):0.934 for water stress and 0.890 for salt stress. This effect on the velocity coefficient and latency time was more moderate or lower. The thresholds of tolerance to salinity and water deficit found were 150 mM and −1 MPa, respectively, for which the lowest FGP values were recorded with 16.25% for water stress and 11.10% for salt stress.

Excess salt in the soil has negatively affected the cultivation of forage crops, such as white oats. Consequently, it is crucial to seek alternatives capable of inducing salt stress tolerance in these plants. The present study focuses on investigating the effects of salicylic acid in mitigating salt stress on seed germination and initial growth of white oats. The experiment was conducted in a completely randomized design, with five concentrations of salicylic acid (0; 0.5; 1; 1.5 and 2 mM) and three levels of salinity (0, 50 and 100 mM), with four replicates. The seeds were sown on germitest paper and stored in a Biochemical Oxygen Demand chamber set at 20 °C and a 12-hour photoperiod. Tests were conducted for germination, first count, length, and dry mass of seedlings. Excess salt in the medium resulted in reduced germination and initial growth of white oat seedlings, while salicylic acid was not harmful to seed germination up to 2 mM. Conditioning white oat seeds with salicylic acid can be used to mitigate the negative effects induced by salt stress, depending on the intensity of the stress and the concentrations used.

“…According to Barichello et al (2021), a decreased root length is related to damage caused by the toxic effect of excess salts, because the concentration of ions in the cytosol becomes cytotoxic in relation to the ions, which causes protein denaturation and membrane destabilization and may ultimately result in cell death.…”

Soybean stands out among the crops with the greatest application of transgenics, mainly for tolerance to herbicides, pests, and diseases; however, studies on salt stress in genetically modified plants are scarce. This study aimed to evaluate the tolerance of both traditional and genetically modified soybean genotypes to saline stress during the germination and seedling phases. Seeds of 13 soybean genotypes were selected (five traditional (BRS Carnaúba, BRS Pérola, BRS Tracajá, BRS Sambaíba, and FTR-4389) and eight transgenic (BRS Sambaíba RR, BRS-333-RR, BRS-9820- RR, PAS-13565-74-RR, PAS-11711-007-RR, BRS-918-IPRO, AS-3810-IPRO, and M-8210-IPRO)), subjected to four osmotic potentials (0.0, 0.1, -0.2, and -0.3 MPa). The seed quality was evaluated using the following variables: the germination percentage, germination speed index, shoot length, root length, dry mass accumulation, and salinity tolerance index. All variables were found to be affected by salt stress. However, the conventional genotypes, BRS Carnaúba, BRS Pérola, BRS Tracajá, and BRS Sambaíba, and the RR group PAS-13565-74-RR, and PAS-11711-007-RR were tolerant to salinity, whereas the genotypes FTR-4389 (conventional) and BRS Sambaíba RR (RR) were less tolerant to salt stress, and all genotypes in the IPRO group were moderately tolerant to salt stress.
