To evaluate the effect of different levels of Nacl concentrations on cultivars of Egyptian, Red and Persian clovers, an experiment was carried out under pilot project intended to completely randomized with 3 replications at Islamic Azad University, Roudhen branch, in 1391 (2012). NaCl concentrations were of 0, 150 and 300 mM/Liter. The traits included radicle length, plumule length, and wet weight of radicle and plumule as well Ratio of plumule length to radicle length. The results of variance analysis showed that there are significant differences among various clover cultivars and NaCl concentration. The relevant traits decrease with the increase of salt concentration. Consequently, various clover cultivars have shown different responses. Therefore, according to Duncan’s mean comparisons method, the Persian clover has shown more resistance to NaCl than other clover cultivars and could have the significant growth in radicle length and plumule length of 150 mM NaCl concentration.
