Abstract: 

In order to investigate the effects of  salinity on germination of common bean cultivars an experiment was conducted at the laboratory of the Islamic Azad University, Eghlid Branch in 2009. Effect of four salinity levels included 0, 1, 2 and 3 ds/m on seed germination percentage root and shoot length and K and Na accumulation in four common bean cultivars included Jules, daneshkadeh, Khomein and G14088 was studied. The experimental design was factorial based on completely randomized design with three replications. Result showed that salinity had significant effect on seed germination percentage. The highest and lowest germination percentage was observed in 0 and 3 ds/m respectively. Salinity reduced root and shoot length. Salinity caused Na accumulation in germinated seeds, but reduced amount of K. Jules cultivar had the maximum germination percentage and the lowest Na amount at 3 ds/m salinity treatment. According to measured traits, Jules and G14088 cultivars were the most resistant and sensitive to salinity, respectivly.
