The objective of this study is to compare the effect of five different Nacl
concentration (0,50,100,150,200 mM) on seeds germination and seedling growth of two
cultivars of soybean (sb-44,sb-172).
Seeds were germinated in petri dishes with sterile
filter paper moistened with 10 ml
of test solution at 25 c˚ in dark .
The obtained results showed that germination percentage , length of root and
hypocotyl were decreased with the increase of the Nacl concentration in the medium. The
best values was from cultivar sb-44 .
After seven days of incubation , significant differences were observed between
control and treated seeds .
Germinated seeds were subcultured on basal Murashige and Skoog medium solid at
the same Nacl concentration . The roots growth was mor affected by 200 mM Nacl
compared to seedling growth .
Plantlets were transfered into pots with nutrient soil , irrigated with saline water and
were adapted at laboratory . we obtained good plants grew to maturity in 10- 12 weeks .
