| Abstract | ||
| Salinity stress is one of the most severe environmental factors that reduce growth and development of plants. This study was carried out to evaluate the effects of salinity levels as NaCl salt and soaking with molasse and vinasse on germination parameters and length of both root and shoot of maize seedlings. Seeds of maize were germinated in glass Petri-dishes (10 cm in diameter). Ten seeds were put in each dish and moistened with 10 milliliters solutions of NaCl zero (control), 3.0, 6.0 and 9.0 dSm-1 as salinity levels. The germination percentage, germination rate, germination index and length of both root and shoot were determined. The obtained results showed that all growth parameters under study decreased with increasing the salinity level, except little positive impact on the length of root and shoot occurred with the seeds soaking in vinasse which the seeds tolerated of salinity. The results also showed that soaking the maize seeds in molasse reduced all germination parameters under study. | ||
