| Abstract | ||||
| This work aimed to evaluate growth of Stevia rebaudiana under stress conditions. The plantlets were cultured on modified MS medium supplemented with different concentrations of NaCl at 0.0, 5000, 7500 and 10000 ppm for salinity stress, as well as mannitol at 0.0, 5, 7.5 and 10 bar. Results showed that the plantlet growth characters decreased as salinity and drought stress level increased, Plantlet growth traits significantly varied under deferent stress levels. Drought strees was more sever on plantlet growth than salinity stress. The highest values for plantlet growth traits were observed at 5000 ppm salinity level while the lowest values were observed at 10 bar drought stress. Some treatments were promised stevia tolerance under both of salinity and drought stress conditions. | ||||
