摘  要：
[目的]研究不同浓度NaCl胁迫下罂粟幼苗的生长及生理生化特性的变化,为罂粟抗盐性综合研究提供理论基础。[方法]利用不同浓度的NaCl溶液对罂粟种子进行处理并模拟盐胁迫环境,测定相关的生长及生理指标。[结果]NaCl浓度的增加促使罂粟幼苗的苗高、根长、根冠比、根系含水量、茎叶含水量均明显下降。幼苗叶片中脯氨酸、丙二醛含量也随NaCl浓度的增加而上升,且高浓度下上升幅度大于低浓度。[结论]60~90mmol/L是罂粟的耐盐临界点。当盐浓度增加到180mmol/L时,幼苗基本枯死。

摘  要：
[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.
