Strawberry is one of the unique small fruits which it’s annual (in glasshouse) and perennial culture has been expanding. This plant is sensitive to salinity. This research was done to investigate the effects of different salinity levels (0, 15, 30, 45 and 60 mM NaCl) on changes of vegetative and reproductive growth and fruit quality of strawberry in hydroponics system. The experiment was done based on a randomized complete blocks design with three replicates. The results showed that by increasing the level of salinity, in addition of considerable loss of fresh and dry weight of plant shoot and root parts, leaves number and area also reduced significantly so that the plant yield at different salinity levels of 15, 30, 45 and 60 mM reduced by 20, 42, 45 and 65% respectively compared to control. The salinity stress also resulted in reduced leaf chlorophyll and relative water content, fruit TSS and titratable acidity while the amount of leaf electrolyte leakage, necrosis area and percentage, fruit anthocyanin, antioxidant capacity, phenolic content, proline and firmness were enhanced by increasing the level of salinity. Totally the majority of changes in response to using salinity stress were observed in vegetative and reproductive plant growth, while, changes in the properties of fruit quality was less affected by salinity.
