盐胁迫是制约土壤农耕的一个重要环境因素，盐渍化土地影响植物正常吸收营养、阻碍植物生长。以小麦种子为材料，分别用4组溶液对小麦种子进行处理，研究一定质量浓度的Ce（NH4）2（NO3）6对盐胁迫下小麦种子萌发、根系生长的影响。结果表明，当用0.8%的NaCl溶液对小麦种子进行盐胁迫时，溶液中含10 mg/L的Ce（NH4）2（NO3）6能够提高盐胁迫下小麦种子的吸水量、发芽率、根长。这表明稀土元素铈对于小麦种子的生长具有一定调节作用，在一定程度上能降低盐胁迫对小麦种子的危害。

Salt stress is one of rigorous environmental problems faced by soil farming areas, which impedes nutrition absor-ption and development of plants. In this study, the seeds of wheat are soaked with certain concentration of Ce(NH4)2(NO3)6, the influence of Ce(NH4)2(NO3)6 on the physiological effect of wheat seed under salt stress is investigated. The results show that the Ce (NH4)2 (NO3)6 treatment of 10 mg/L concentration enhanced the absorbent degrees and the seed germination and root, when the seedlings have been immerse with 0.8% NaCl. We discover that Ce obtains a certain recover in growth activity when Ce is added into conditioning fluid under salt treatments, and Ce is detected to reduce the hazard from salt stress.
