| Abstract | ||
| Salt stress using (NaCl) treatments were conducted on strawberry varieties (Fragaria x ananassa cvs. Rosilinda, Selected Tahrier and Diamond ) grown under various salt level, viz; 0.98, 2.5 and 4.5dS /m were applied to the plants for 9 months in the field experiments. The field experiments were conducted in 2004/2005 and 2005/2006 seasons at Sidi salem district, Kafr El –Shiekh province, Egypt. The salinity levels of experiment site were salinised using Nacl and Cacl at the ratio of 2:1 The main results of current study could be summarized as follows; Increasing salinity significantly restricted growth of various strawberry varieties, length, diameter, volume and weight of fruits as well as fruit yield in both seasons. Furthermore, increasing salinity level up to higher salt level of 4.5 dS/m significantly improved fruit quality whereas, it increased total soluble solids. The salinity levels didn't affected the flowering date in the first season while, in the second season, the flowering date significantly prolonged as salinity levels were increased. High salinity concentrations caused serious reductions in growth parameters, fruit yield characters and fruit yield /plant. Considering the performance of cultivars, the three tested strawberry significantly varied in all aforementioned traits. The strawberry cultivar Selected Tahrier was characterized as more salt tolerant than Rosilinda and Diamond under saline conditions. The interaction effect came to confirm the superiority of abovementioned variety. | ||
