This experiment was carried out aiming to determine the Catharanthus roseus Don resistance against
salinity, due to the increasing salinity of soil, and the importance of this plant as an ornamental flower, as well
as the little information available on its tolerance against salinity during the germination period. In order to an
experiment was conducted in randomized completely design factorial. Sodium chloride was used for induce
salinity stress. These factors include cultivar and salinity levels with Electrical Conductivity (EC) of 1, 2, 4,
6, 8, and 10 dS/m. The results of variance analysis showed that salinity effect at level 1% on the germination
percentage, germination rate, radicle and plumule length, seedling wet and dry weight and ratio of plumule
length to radicle length were significant and they were reduced. While the cultivar and interaction of cultivar
and salinity treatments were non significant. According to the results, response of two cultivars to the salinity
was the same and there was no difference between them.
Key words: Catharanthus roseus Don, germination, salinity stress, sodium chloride, , ,
