摘　　要：水盐是制约植物正常生长发育的主要胁迫,研究植物叶绿素荧光参数对水盐胁迫的响应机制有利于深入了解植物的抗旱耐盐机理,对水分亏缺地区进行节水灌溉和盐碱地开发利用具有重要意义。本文主要论述了水盐胁迫下植物叶绿素荧光参数的变化规律、耐盐机制,揭示了不同叶绿素荧光参数在水盐胁迫下的变化机理和相应参数变化对植物生长所造成的影响,总结了不同胁迫下植物生理、生化的改变条件,以期为更加深入了解植物对水盐胁迫的内在响应机制提供参考。Water and salt are the main stresses that restricts the normal growth and development of plants.Studying the response mechanism of plant chlorophyll fluorescence parameters to water and salt stress is conducive to understanding the drought and salt tolerance mechanism of plants,which are of great significance for water-saving irrigation and the development and utilization of saline-alkali land in water deficit areas.In this paper,the changes of chlorophyll fluorescence parameters under water and salt stress and the salt tolerance mechanism were mainly discussed,the change mechanism of different chlorophyll fluorescence parameters under water and salt stress and the effect of corresponding parameters on plant growth were revealed,the physiological and biochemical change conditions of plants under different stresses were summarized,so as to provide reference for further understanding the internal response mechanism of plants under water and salt stress.
