The Photoacoustic Spectrometer (PA technique) could be applied to sophisticatedly measure the oxygen evolution kinetics/phototherm kinetics/energy storage (ES) kinetics during the light induction period. The present paper studied the relationship between chlorophyll fluorescence and oxygen evolution kinetics by PA and Chlorophyll fluorescence technique. The phototherm kinetics and ES also measured by PA. The existed some relationship between PA oxygen evolution and fluorescence parameters during light induction period. The minimum value of ES at the beginning of light induction period might reflect the cyclic electron transfer around PSI. The huge gas uptake under the condition of high concentration CO2 could be notified by PA. This huge gas uptake might be fast CO2 solubzation or all kind of Mehler reactions.
