The present investigation was carried out during three successive years (2000- 2002), in order to evaluate three grape cultivars namely, Early Superior, Flame seedless and Thompson seedless, for salt tolerance under in vitro conditions. The main results can be summarized in the following points: A. Effect of Cultivars 1- Early Superior gave significantly the highest shoot multiplication percentage and average number of new proliferated shoots per original shoot. in the 1st, 2nd and 3rd subcultures, followed by Flame seedless and Thompson seedless. In the meantime, Early Superior achieved significantly the highest leaf P, K, Na, Mg, total chlorophyll contents and peroxidase activity, followed by Flame seedless and Thompson seedless. Moreover, Early Superior recorded significantly the highest leaf N and proline contents, as compared with Flame seedless and Thompson seedless. On the contrary, Thompson seedless exhibited significantly the highest shoot injury percentage and leaf Ca content, followed by Flame seedless and Early Superior. Also, Flame seedless cv. exhibited significantly the highest average length of new proliferated shoot.
