Application of chlorophyll fluorescence analysis technique in experimental teaching

Plant photosynthesis is an important research content of plant physiology and related courses, and chlorophyll fluorescence analysis technology is an important technical means to quickly and accurately detect plant physiological status. In this paper, a comprehensive design experiment project was designed to study the effects of different temperature and water conditions on plant photosynthesis by chlorophyll fluorescence analysis technology, and to study the effect of different temperature and water stress on plant photosynthesis characteristics. The implementation of this experimental project can familiarize students with the working principle of the modulated chlorophyll fluorescence meter and grasp the chlorophyll fluorescence analysis technology, so as to improve students’ ability to independently carry out scientific research projects, as well as their innovative consciousness and innovative ability.
