Key words: Vitis vinifera L., Flame Seedless, Perlette, salinity.


Vitis-vinifera-Black-HamburgSalinity is one of the limiting factor for grape growing in arid and semi-arid areas. Hence he effect of salinity on some physiological and biochemical characteristics of two seedless cultivars of grape namely Flame Seedless and Perlette under salinity stress were investigated. The design of the experiment was factorial arrangement in a complete randomized design with four replications. Five levels of salinity (0, 25, 50,75 and 100 m molar of NaCl) in irrigation water were surveyed on rooted cuttings of both cultivars. Results indicated that with increasing salinity levels photosynthesis, amount of soluble proteins and relative leaf water content was decreased and amount of proline and soluble sugars were increased. Ion leakage of cell membrane and malondialdehyde were increased with increased salinity. Withoute salinity application Perlette cultivar produced the best values for physiological and morphological indices. In general, Perlette cultivar proved more tolerance against salinity than Flame Seedless cultivar did.
