Germination of castor seeds from five dwarf hybrid genotypes, compared to a ‘Local’ genotype selected by the University of Catania from a Tunisian population well adapted to the Mediterranean environment, was studied at five different salt levels (0, −0.3, −0.6, −0.9, and −1.2 MPa) in order to assess seed germination performance under stress conditions. The results confirmed that optimum moisture (0 MPa) ensured 100% of germination; on the contrary, salt concentration negatively influenced the final germination percentage (FGP) and radicle elongation, causing severe consequences for plant establishment. At a level of −1.2 MPa, no germination occurred, while a level of −0.3 MPa slightly affected the seed germination of the dwarf genotypes, which achieved 77.3% of germination, contrary to the ‘Local’ genotype, in which germination was kept stable. Higher levels of salt (−0.6 and −0.9 MPa) caused a linear decrease in FGP and radicle elongation. Overall, the dwarf hybrid ‘C1019’ performed better at higher salt impositions, as did ‘C857’, confirming these genotypes were the most tolerant among the dwarf hybrids. Conversely, ‘C1013’ turned out to be the most susceptible genotype, followed by ‘C1008’. On the other hand, the ‘Local’ castor genotype was the best-performing genotype at −0.3 MPa and the most tolerant genotype in terms of salt concentration and germination time, which were accurately predicted by the hydrotime model, validating it as a valid method of assessing the germination response of castor seeds to Ψ.

Soil and water salinity is an important limiting factor affecting yield and production levels in arid and semi-arid areas. Salt tolerance during germination is an important parameter that also affects the other plant development stages. In this respect, this study was designed to determine the responses of pumpkin seed varieties (Develi, Ürgüp, Hybrid) to different NaCl salinities. The study was carried out in 2022 in the laboratory of Biosystems Engineering Department of Erciyes University in randomized plots design with 3 replications. Experiments were conducted with 5 different water salinity. Germination percentage (GP), germination index (GI), mean germination time (MGT), seedling vigor index (SVI), ion leakage (Il), radicula length (RL) and plumule length (PL), root and shoot fresh and dry weights and some mineral composition (Na, K, Ca) were examined. Proline, antioxidant capacity, total phenolic and DPPH content were significantly affected by salinity. In scatter plot correlation analysis SVI a positive correlation was observed between GP (r2 = 0.774), GI (r2 = 0.745), RL (r2 = 0.929), FRW (r2 = 0.837), FSW (r2 = 0.836), DRW (r2 = 0.894), AC (r2 = 0.747), TP (r2 = 0.640) and DPPH (r2 = 0.635). It was determined that there were negative correlations between SVI and MGT (r2 = − 0.902), II (r2 = − 0.588), DSW (r2 = − 0.682) and PR (r2 = − 0.344). Present findings revealed that investigated parameters were significantly affected by increasing salinity levels. While Hybrid cultivar was the most affected by salinity, Develi cultivar was found to be resistant to saline conditions.
