One of the unique properties of earlier stages of plant growth is germination. germination is morphological expression of various metabolic activities in seeds. Plants exposure to the abiotic stresses for instance salinity that influence physiological processes, anatomy, developmental systems and plant development. Agriculture production under arid and semi-arid zone is low owning to many factors for example accumulation of salts in soils and water, total of land area under salinity is about 953 million ha. The aim of this research was to evaluate the germination characters of five faba bean (Vicia faba L.) varieties [Nubaria (1), Giza (843), Sakha (1), Sakha (3) and, Sakha (4)] were using saline solution containing (0, 1000 and 2000 ppm NaCl), were utilized to examine their water uptake, germination percentage, germination index, relative salt injury rate, radicle length, sprout fresh and dry weight, weight losses and seed volume using saline solution . Results indicated that the higher concentrations of salt have a negative impact on water uptake, germination percentage, radical length, sprout fresh and dry weight, seed volume, and relative salt injury rate. At all salinity concentration, the five varieties showed different degrees of salt tolerance. Sakha (3), (4) and Giza (843) had a better salt tolerance index than the other Nubaria (1) and Sakha (1). Nubaria (1), Giza (843) had the highest percentage and index of germination, while Sakha (1) had the shorter radical length and susceptible to salt injury rate. Moreover, Giza (843) and Sakha (3) genotypes can be considered as tolerant to salt stress compared to the other ones. These genotypes also could be used in the breeding program for enhancing faba bean cultivation in newly reclaimed lands. Data suggest a test of seed germination may be useful to use in developing new lines of faba bean to grow in saline soils.
