| Abstract | ||||
| High salinity stress levels decreased while pre- soaked and foliar spray applied antioxidants increased growth parameters such as leaf area , stem dry weights , and leaves dry weights. Heigh salinity level ( 9000 mg/l ) was more effective in decreasing all growth parameters . while applied antioxidants ( pre-soaked and foliar spray) ASA and Yeast extract were more effective in increasing all growth parameters . Moreover , it could be show that applied antioxidants partially alleviated the harmful effect of salinity stress which enhanced growth parameters .Growth parameters which increased due to applied antioxidants combined with salinity stress levels were still than control . Salinity stress levels decreased soybean yield, and 9000 mg /l was the most effective in this respect. On the other hand, applied antioxidants (pre-soaked and foliar spray) increased seed yield of soybean plant. The data also show that applied antioxidants enhanced seed yield grown under stress condition comparing with untreated plants. This increase was less than control plant. It could be show that applied antioxidants partially counteracted the harmful effect of salinity stress on seed yield of soybean plant. | ||||
