The effect of surfactant solution on flax oil and chicory seed germination indices under salt stress

In order to study the effect of surfactant solution on of Flax oil and Chicory seed germination indices under salt stress, an experiment was carried out as factorial in a completely randomized design with 3 replications in the laboratory of Science and Seed Technology, Shahed University. Treatments were salinity (control, 3, 6, 9, 12 ds/m) and surfactant solution (0, 1, 2, 3, 4 ppm), respectively. In this experiment were studied treatments Shoot length, Root and Seedling, Root to shoot length ratio, germination Percentage, germination rate, Seedling dry weight and Mean germination Time. Results showed that salinity and concentrations of surfactant had significant effect on most traits. So that the salt concentration of 12 ds/m reduced seedling length and germination rate by 8.3% and 20.8% in Flax seed oil, respectively. Also 30% of the dry weight reduced in Chicory plant. Surfactant solution with concentration of 3 ppm increased 107 percent the average seedling root length, 35 percent length, 91 percent of radicle to shoot and seedling dry weight in Flax oil plant. Also the concentration of 2 ppm of surfactant at low salt levels produced the most plumule and radicle length on both plant, and produced the most radicle length and allometric of chicory plant. At high concentration of surfactant with low levels of salinity reduced the average time required for germination. In general, the results showed that surfactant solution can be improved the germination tests, as well as some adjusting for the salinity effect.
