“…A decrease in the division and elongation of plant cells decreases their final size, consequently leading to a decrease plant height, the leaves number, leaf area, shoot fresh mass, and root length growth, as reported previously (Cabrera, 2003;Cassaniti, et al, 2009;. A decrease in growth parameters in different ornamental plants owing to salinity has also been mention in gladiolus (Cerquera et al, 2008;, marigold (Valdez-Aguilar et al, 2009), and Zinnia (Zivder et al, 2011). The drought-induced reduction in the enlargement and division of cells can account for the reduction in individual leaf area and number of leaves (Dale, 1988).…”

“…These seedling parameters were drastically decreased by salinity. Similarly, the highest root length was recorded in the control by Zivdar et al (2011) and the lowest was at 12 dS m -1 in Z. elegans L. Zanetti et al (2019) revealed that plumular and radicular length decreased at switchgrasses [Alamo (lowland) and Shawnee (upland)] as salinity increased and Shawnee had a considerably lower germination rate than Alamo, in particular under critical salinity level (14 dS m −1 ). Bybordi and Tabatabaei (2009) evaluated germination and seedling responses of five rapeseed cultivars to salinity stress levels [0 (control), 5, 10, 15, and 20 dS m -1 ].…”

“…The germination percentage of Dreamland cultivars were slightly increased with salinity compared to control. In parallel, Zivdar et al (2011) found that increasing salinity decreased seed germination at Z. elegans. Hannachi and Van Labeke (2018) reported that seed germination parameters (germination percentage, mean germination time, and mean daily germination) were adversely affected by increasing saline stress in Solanum melongena L. Seed germination of eggplant strongly reduced at 80 mM NaCl.…”

The Zinnia genus which belongs to the Asteraceae family is an annual, multipurpose ornamental plant. Zinnia plants are cultivated not only in landscape but also as the potted plant and cut flower. One of the most important problems in the world is salinity in soil and water. The aim of this study was to determine the effects of salinity on twenty Zinnia cultivars during seed germination and early seedling growth. The salt was applied by irrigating seeds with 0 and 100 mM salt solutions. Radicle emergence, seed germination, root, hypocotyl and cotyledon lengths, relative growth index of the root, and seedling fresh weight were evaluated. At the end of the study, the radicle emergence reduction was the highest value in Zinnita Rose (52%). The highest reduction rates on seed germination were at Swizzle Cherry-Ivory, Double Zahara Raspberry Ripple (48%), and Double Zahara Yellow (48%). Root lengths of all Zinnia cultivars were dramatically decreased by salt stress. According to weighted ranked evaluation, Dreamland Ivory and Dreamland Coral were more tolerant to salt stress than other Zinnia cultivars. However, in general Zinnia cultivars were relatively sensitive to salt stress at the germination stage.

“…High salinity reduces germination, seedling emergence, and ultimately crop establishment (Stumpf et al 1986;Fowler 1991;Khan and Ungar 1999;Puppala et al 1999;Ashraf 2001;Qasim et al 2003;Ashraf and Foolad 2005;Guma et al 2010;Jamila et al 2010;Zivdar et al 2011). Ahamad et al (2012) reported salinity stress significantly affected the rate of germination, root and shoot growth of four canola cultivars, while Long et al (2015) reported that root growth of canola is affected by salinity stress as early as 12 h post-exposure.…”

“…Generally, germination and seedling vigor are considered to be highly sensitive to saline conditions, which lead to a considerable reduction of yield and biomass production (Hamdy et al 1993). Indeed, salt stress reduces germination and establishment of seedlings in many plant species (Fowler 1991;Khan and Ungar 1999;Guma et al 2010;Jamila et al 2010;Zivdar et al 2011), including B. napus (Puppala et al 1999;Ashraf 2001;Qasim et al 2003). Brassica napus seed germination decreases sharply under salinity stress, from 87% at 0 dS m −1 to 0.8% at 26 dSm −1 (Puppala et al 1999).…”

Salinity is a major limiting factor for early crop establishment and yield. In this study, 131 Brassica napus genotypes were evaluated for germination and early seedling growth in Murashige & Skoog medium supplemented with NaCl. Selected genotypes were then evaluated for tolerance to salinity at the vegetative and reproductive stages in greenhouse and semi-hydroponic systems using 1.4, 5, 10, 15, 20, and 28 dS m−1 salt stress. Relative salt tolerance (RST) was calculated and compared with genotype performance under no salt stress (control). The area under the germination progress curve (AUGPC) varied from 53 to 90 in the control and from 6 to 89 under 200 mmol L−1 NaCl stress. The seedling vigor index (SVI) ranged from 200 to 1606 and 10 to 736 in the control and 200 mmol L−1 salt stress treatments, respectively. The RST for germination, root length, shoot length, and SVI ranged from 8% to 97.7%, 2% to 98.3%, 6.5% to 70.8%, and 1.9% to 83%, respectively. Root length was most severely affected by saline conditions, followed by shoot length and AUGPC, when RST percentages of these traits were compared among responses of the 131 genotypes. Genotypes showed varying levels of proline and glucosinolate accumulation under different levels of saline stress. Greater accumulation of proline and glucosinolates was recorded with increased salinity level. This study indicates that variation exists in seedling and adult plant responses to saline stress in B. napus genotypes and that improvement for salinity tolerance requires selection at the seedling, vegetative, and reproductive plant stages.
