Germination and seedling responses of five rapeseed cultivars ('Elite', 'Fornax', 'Licord', 'Okapi', and 'SLM046') to salinity stress levels (0 cont, 5, 10, 15 and 20 dSm-1) evaluated in aRCBD base factorial design in three replicates in the glasshouse. Increasing Salinity decreased significantly rate and final germination, radicle and plumule length and fresh weight. The decreasing rate was different among cultivars. Salinity and cultivar interaction effect were significant in all attributes. Three parametric logistic regressions fitted the best estimation between germination and salinity levels. The highest and the lowest B coefficient belonged to 'Elite' and 'SLM046' that shows high and low susceptibility to salinity. Ld 50 threshold for germination for 'Elite' and 'SLM046' were 10.46 and 23.01 dSm-1, respectively. Tolerance ranking for cultivars was 'SLM046' > 'Okapi' > 'Fornax' > 'Licord' > 'Elite'. This classification belonged to early-season tolerance and it is necessary to study the next growth period to evaluate salinity tolerance rank among cultivars.

- Effect of Salinity on Seed Germination and Seedling Development of Sorghum (Sorghum bicolor (L.) Moench) Genotypes (2020, background): “We included early stages of plant development, because there is well documented that germination and seedling features are the most viable principles, and the final plant performance depends heavily on seedling specifications [20,46].”
- The Influence of Salt Stress on Seed Germination, Growth and Yield of Canola Cultivars (2010, unknown): “Therefore, seeds with more rapid germination under salt stress and/or normal conditions may be expected to achieve a rapid seedling establishment and more salt tolerance and hence higher yields (Munns, 2002; Bybordi and Tabatabaei, 2009).”
