Abstract: 

Tolerance to salinity was studied during germination of Brassica napus L., and on two cultivar, Hayola 401 and RGS, of these plants. This study was done in three levels of salt NaCl (75, 100 and 150 mM) and one level gibberellic acid (0.05mM) and one level ascorbic acid (0.2mM). Experiments determine percent and rate of germination were done on three salinity treatments (75, 100 and 150 mM), three salinity in addition gibberellin treatment, three salinity in addition ascorbat treatment and three salinity in addition gibberellin and ascorbat treatment. Control sample was distilled water.
Experiments are done in the same situation and three repetitions. Data are analysis by ANOVA and Duncan tests, and comparison the average of data was done with 95% safety index. According results, salt stress decrease percent and rate of germination in both cultivars. Gibberellin treatment was positive effect on salinity at low concentration of salinity.
Ascorbat treatment was positive effect on salinity in three levels of salinity too.
