Abstract: The seeds of genetically modified fodder sugar beet were treated with different concentration under sodium chloride conditions.The germination percentage,seedling growth and the response of the seeds after removing salt stress were studied in order to provide theoretical basis for agricultural production.The results showed that 50-150 mmol/L NaCl had no significant effects on the seed germination.While under 100 mmol/L NaCl conditions,the germination percentage is highest in all salt stress treatments,which increased 6.78% than the contrast treatment.With the increasing of salt concentration,the germination percentage had different decrease.But after removing the salt stress,the seeds could germinated rapidly and the germination percentage were also improved.At the same time,the result also showed that the scion and radicle had different response to the sodium chloride concentration,and the higher salt concentrations had more influence on the radicle.

Key words: Genetically modified fodder sugar beet, Salt stress, Germination, Recovery, Growth of seedlings
