| Abstract: Almost all changes in photosynthetic processes can be reflected by chlorophyll fluorescence.Chlorophyll fluorescence kinetics technology has become one of the most widely used techniques for studying the physiological ecology of plants.This paper presents a set of software that analyzes chlorophyll fluorescence parameters and helps the study of photosynthesis in the process of light energy absorption,transmission,dissipation,distribution and etc.The software is programmed in JavaScript,which reads the measured data from excel tables and automatically draws OJIP curves,as well as the corresponding OJIP curvature,first derivative curve and second derivative curve.Users can use the interactive interface to set an interval,and the software will automatically locate I and J points according to the set algorithm.It supports manual adjustment and optimization of the position of the feature points.The results of the localized feature points are exported and stored as files,making it easier and faster to study chlorophyll fluorescence signals. |
