“…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.

As typical arid vegetation, Calycotome villosa is an annual herb playing an important role in folk medicine. In this research, the influences of temperature and salinity on germination of C. villosa seeds gotten from southern Tunisia were investigated. The germination responses of the seeds in total darkness were determined over an extensive array of temperatures (5, 10, 15, 20, 25, 30, 35 and 40°C) as well as salinities (0, 50, 100, 150, 200, 250 and 300 mM NaCl). Seeds of C. villosa were able to germinate at temperatures between 5 and 40°C. Temperatures between 20 and 25°C seemed favorable to germinate these species. The minimum temperature beyond which no germination is expected was 0°C. Utmost germination percent were gotten in non-saline situations as well as arise in NaCl absorptions increasing repressed germination of seed. The rate of growth reduced with arises in salinity on all temperatures. Salt stress decreased both the percentage and the rate of germination. Percent of germination reduced with growing salinity and sternly restricted at 250 and 300 mM. Findings from this research might function as valuable information for C. villosa habitat establishment and renovation plans.
