Objective: The effect of different soaking concentrations on the growth and development of different varieties of oats was studied by the soaking method with uniconazole. Methods:The experiment was conducted with different oat seeds including Jinyou 8, Kam Ⅲ 1618 and XHY-1, which were treated  with uniconazole with different concentrations(0, 15, 30 and 45 mg·L^-1). Results: The results showed that soaking seeds with different concentrations of uniconazole have “astrict the aerial part but promote the underground part” effect of oats, it will promote root growth; increase chlorophyll and proline content of leaf, it also will reduce the content of malondialdehyde and enhance plant stress resistance, promote the industrialization of oats 
cultivation. The morphological indicators and physiological indicators of Jinyou 8, XHY1 should be significantly better than KamⅢ 1618, and in this experiment Jinyou8 and XHY-1 have their uique indicator in various treatment with different uniconnazole concentrations. Conclusion: When combining with the method of uniconazole soaking seed treatment, in the actual production of Shanxi oats, it is recommended to use Jinyou 8, XHY-1 in production, and the appropriate soaking concentration of uniconazole is 15 mg·L^-1.
