Paper Abstract

Adopting high-power light-emitting diode (LED) as excitation light source, the study designed a rapid detection system for fluorescence parameters based on MINIPAM. The system uses a microcomputer as the core of the programmable power supply to provide constant current drive of the LED array, and the LED array as a fluorescence excitation light source produces light photochemical system needed. It also uses MINIPAM to detect the fluorescence, analyzing the fluorescence parameters of the mathematical model, studying the plant photosystemⅡ light response curve. The System is of great significance in the evaluation of chlorophyll photosynthesis ability and the plant physiological stress response and the appropriate mechanism.
