[Application of the fast chlorophyll fluorescence induction dynamics analysis in photosynthesis study].

The changes in PSII performance of the photosynthetic apparatus caused by environmental stress or senescence have been explored widely by applying the chlorophyll fluorescence technique, mainly by using the modulated fluorometer. In recent years, an alternative approach via analyzing chlorophyll a fluorescence transient using the continuous excitation fluorometer has been developed, which offers more information that cannot be obtained by the modulated fluorometry. The JIP-test based on the theory of energy fluxes in biomembranes has been widely used to analyze the chlorophyll a fluorescence kinetics transient helping researchers to have a deeper insight into the primary photochemical reaction in the photosynthetic apparatus. In this paper, the chlorophyll a fluorescence transient and its significance, the parameters involved and their significance in the JIP-test, and the application of the fast chlorophyll fluorescence induction dynamics analysis in photosynthesis study are introduced combining some results of the author's.
