“…Therefore, a high germination potential combined with an e cient root system in CT and CC can guarantee a suitable establishment of these species in saline soils, which is a key factor to high competitiveness towards weeds and other species whose seeds are rendered nonviable in saline conditions (Fercha et al 2016). Likewise, studies on rice (Arvas et al 2023) and linseed (Linum usitatissimum) genotypes (Singh et al 2021) found that the resistant genotypes tended to have longer roots and lower yield losses in saline conditions than sensitive genotypes. These studies also noted that root length of the resistant plants was increased by low salinity levels, while sensitive genotypes did not reveal such a response.…”

“…There is a growing interest in exploring the saline-adapted species and the mechanisms by which they can survive in saline conditions as a strategy toward mitigating the effects of salinity (Zhou et al 2021; Arvas et al 2023). In this regard, seed germination and seedling growth potentials as well as antioxidant mechanisms of the ve Asteraceae species, which were previously chosen as the promising species in marginal stressed lands, were evaluated in response to salinity stress.…”

Exploring the saline-adapted species and the mechanisms by which they have evolved in saline conditions would be a feasible way to utilize saline soils. Based on this approach, this study aimed to evaluate the seed germination and seedling responses of the five abundant Asteraceae species to salinity stress and determine the antioxidant defense strategies by which these species demonstrated variations in the tolerance of salinity. Milk thistle (Silybum marianum), blessed thistle (Cnicus benedictus), pot marigold (Calendula officinalis), safflower (Carthamus tinctorius), and cardoon (Cynara cardunculus) were subjected to 0 (control), 50, 100, 150, 200 and 250 Mm NaCl concentrations. Calendula officinalis (CO) showed the highest, Silybum marianum (SM) and Cnicus benedictus (CB) moderate, and Carthamus tinctorius (CT) followed by Cynara cardunculus (CC) the least inhibition of seed germination and seedling growth at all given salinity levels. Each species utilized different antioxidant mechanisms in response to salinity. Peroxidase (POX) was the major antioxidative enzyme in resistance species, CT and CC, while catalase (CAT) and superoxide dismutase (SOD) were more pronounced in moderate, SM and CB, and susceptible, CO, species, respectively. Besides, all species expressed a great ability to accumulate considerable amounts of proline in response to salinity, which was more evident in the 150 and 200 Mm NaCl concentrations. From the results, it can be concluded that CT and CC with longer seedling roots, higher POX activity and proline accumulation coupled with lower cellular damage under increased salinity demonstrated a more saline-tolerance capacity in comparison to other species.

This study estimates genetic variability and correlations among germination and seedling traits conferring salinity tolerance in rice accessions. Five rice accessions were screened under salinity levels of 0, 50, 100, and 200 mM NaCl in a controlled laboratory setting. Traits such as germination energy, capacity, shoot and root length, and biomass were measured. Data were analyzed for variance and correlations to assess variability and trait relationships. Significant genetic variability was found among accessions for all traits. Germination energy showed the highest coefficient of variation (CV) at 22.29% under control conditions, while fresh shoot weight had the highest CV (34.35%) under 200 mM salinity. Accessions ACC2 and ACC5 consistently demonstrated higher performance in germination energy (23.33 to 53.33% and 10.00 to 41.67%), germination capacity (40.00 to 60.00% and 28.33 to 46.67%), and shoot length (0.67 to 2.97 cm and 0.40 to 3.93 cm) under various salinity stress levels. ACC1, ACC3, and ACC4 showed more variability but maintained some consistency in specific traits, with ACC4 generally showing lower performance across most traits. Genetic parameter estimates indicated high heritability (˃60%) for all traits, with the highest in germination capacity (96.88%). High genetic advance (GAM) was observed for all traits (˃20%), with germination energy showing the highest (107.00%). Traits with high heritability and genetic advance, such as germination energy, germination capacity, and root length, suggest strong genetic control and potential for improvement through selective breeding. Significant correlations were found between germination energy and capacity (r= 0.89 to 0.96) and between shoot length and leaf length (r= 0.92) under stress conditions. Stress tolerance indices identified accessions ACC2 and ACC5 as the most tolerant, with ACC1 showing consistent performance across traits. This study underscores the importance of identifying resilient traits and accessions to enhance salinity tolerance in rice, contributing to improved productivity in saline-affected regions.
