| 摘 要： | 通过总结近年来国内对于向日葵在盐胁迫下的反应机理的研究，从种子、形态发育、光合作用、水分代谢和呼吸作用等方面综述了盐胁迫下向日葵的生理生化反应，并在此基础上概括了盐害条件下向日葵的三大耐盐机制，即渗透调节、离子摄入和‘区域化以及拒盐与离子的选择吸收机制。

| Abstract: | The physiological and biochemical responses of sunflower to salt stress were discussed with respect to the effect of salt stress on seeds,growth,photosynthsis,water-metabolizability and respiration by summarizing the related studies in recent years.And three resistance mechanisms of sunflower to salt stress were generalized.They were osmoregulation,absorption and compartmentation of inorganic irons and mechanisms of resistance to salt and selected absorption to inorganic ions. |
