N2 - To study the effect of salinity on physiological, biochemical and anatomical characteristics as well as the growth and yield of different varieties of melon, a split plot experiment was designed based on RCBD with 3 replication on 3 varieties, resistant (annanasi), semi tolerant (Sabz Isfahan) and sensitive (Gongi) and two salinity levels (0 and 8ds/m according to salinity of wells) in the field of Isfahan Research Station in 2016-2017.Results showed that the fresh and dry weight of shoots decreased with salinity in all varieties. Fresh and dry weight of pulp, skin and seeds, number and fruit weight decreased in sensitive and semi tolerant. Yield decrease in all varieties. fruit firmness in all varieties and fruit acidity decreased in semi tolerant and sensitive and TSS increased. The greatest decrease of photosynthesis, stomata conductance, and CO2 of stomata was in sensitive variety. Transpiration and leaf water potential was more minus. The highest amount of proline, phenol and antioxidant activity was observed in resistant variety. Upper epidermis thickness increased in sensitive variety with salinity and did not change in lower epiderm of leaves. the aim of this research was introducing the tolerate variety to salinity result in introducing Ananasi.
