| Abstract | ||||
| At germination time of some bread wheat genotypes, both dehydration caused by polyethylene glycol (PEG-6000) and salinity initiated by NaCl stresses have been applied at the age of the 7th day to investigate the seedling response of 4 F1 hybrids contrary to their 7 parents. Double wetted sheets of filtering paper included in sterilized pettri dishes were the experimental medium of growing, while, weekly irrigation solutions differed conformably with treatments. Since, drought stress solution was performed with adding 200 g/l of PEG-6000 to distilled water to obtain -0.49 kPa of water potential, and saline solution was performed with solving NaCl in the distilled water to obtain 2000 ppm level. Hoagland solution was concerned for control treatment irrigation, regardless of the first irrigation for all treatments. Observations about stomata, growth and chemical analysis have been recorded around 2 months. Analysis of variance reflected the significance and some of the hybrid ability to stress tolerance. | ||||
