| Abstract | ||||
| Several experiments were carried out during 2006-2007 seasons in Horticulture Laboratory, Faculty of Agriculture Al-Furat Univ. to evaluate three tomato varieties under different levels of salinity at germination stage and select salt tolerant varieties compared with sensitive ones. Split Blot Design with eighth replicates was used. Two factors were applied: Salt concentrations (0, 0.28, 0.57 and 0.85 % NaCl) and three varieties (e.g. Pakmor, Special Back and Call Ace or Ice). Data analysis showed significant differences in response between studied tomato varieties and salinity stress at germination stage. Increasing salt concentration in planting medium –except at 2nd treatment- caused decreased in all studied growth criteria, especially decreasing in germination time and elongating of necessary ability to germinate in all concerned varieties. On the other hand, increasing of salinity caused a growth inhibition, as radicl length, root and shoot living mass were decreased. According to the results, Special Back was more sensitive to high salinity, whereas Pakmor less one and Call Ice the medium. Also, variation analysis showed a exchangeable interaction between varieties and salinity, indicating that varieties had different response at each salinity concentration. | ||||
