Abstract
The fig, a sub-tropical crop, consumes as a table fruit as well as a dry product. Since, salinity is the serious concern of fig production, during 2016-2018, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘Shah Anjirʼ, ‘Atabakiʼ, ‘Kashkiʼ, ‘Matiʼ and ‘Barʼ) were subjected to saline water (0.5, 2, 4, 6, 8 and 10 dSm-1). Then, potein, proline, photosynthetic pigments, superoxide dismutase, catalase, guaiacol peroxidase and ascorbate peroxidase content were compared to introduce the most salt-tolerant cultivar. The results indicated, salinity caused an increase in total protein, proline and activity of antioxidant enzymes, but a decrease in chlorophyll (a, b, total) and carotenoids pigments. According to the results “Siyah” and “Sabz” cultivars were the most salt-tolerant and “Shah Anjir” was the most salt -sensitive cultivar. The ‘Atabakiʼ, ‘Kashkiʼ, ‘Matiʼ and ‘Bar anjirʼ were placed between them

Abstract
The Fig (Ficus carica.L) is a woody perennial crop, cultivated worldwide in subtropical regions. Since, salinity is the main concern of fig industry, therefore, studying the pattern of ion absorption and accumulation contribute during the stress in different plant organs can lead understanding the mechanism of tolerance/sensitivity. So, during 2016-2017, seven fig cultivars (‘Sabzʼ, ‘Siyahʼ, ‘Shah Anjirʼ, ‘Atabakiʼ, ‘Kashkiʼ, ‘Matiʼ and ‘Barʼ) were subjected to saline water (0.5, 2, 4, 6, 8 and 10 dSm-1). Then, ions accumulation of different organs, leaf abscission, dry matter, relative water content, and photosynthetic indices were compared to introduce the most salt-tolerant cultivar. The results indicated salinity caused a decrease in leaf relative water content, photosynthesis rate, K content and an increase in leaf abscission, Cl and Na content. Principal component analysis of the data led to a reduction in the variables with major contributions from the content of K, Na and Na/K of leaf and root, shoot Na, leaf Cl, and RWC. The ‘Siyahʼ and ‘Sabzʼ, as the most salt-tolerant cultivars, had the maximum leaf abscission, the least Na content and the maximum shoot dry matter under salt condition. The ‘Shah Anjirʼ, as the most salt-sensitive cultivar, could not restrict root Cl ex-flux into shoot and leaf.
