[Objective] Changes of growth and physiological and biochemical characteristics of Papaver somniferum L. seedlings with different concentrations of Na Cl were studied to provide a theoretical basis for the comprehensive study of Papaver somniferum L. salt resistance. [Method] Papaver somniferum L. seedling was treated with different concentration of Na Cl solution and salt stress environment was simulated. Its growth and physiological indexes variation were determined. Using different concentrations of Na Cl solution to simulate the poppy seed processing and salt stress environment,its growth and physiological indicators were measured. [Result]The plant height,root length,root shoot ratio,root water content,and stem leaf water content were all decreased with the increase of the concentration of Na Cl. The proline content and MDA content were all increased with the increase of the concentration of Na Cl.[Conclusion]When salt concentration was increased to 180 mmol / L,Papaver somniferum L. seedling basically died. The critical point of salt tolerance of Papaver somniferum L. seedling was 60 mmol / L Na Cl.
