Abstract
The photochemical activity of photosystem II (PSII) illuminated at different temperatures (20-55℃) has been studied. The photochemical activity of PSII preparations incubated at different temperatures in the dark decreased sharply in the range of 40-55°C, and was relatively stable at temperatures 20-40°C. The photochemical activity of PSII decreased with relatively monotonous kinetics in preparations processed at different temperatures and exposed to light, but in the end, it was higher than the activity observed in samples incubated in the dark. The effects of glycerin and sucrose on the PSII inhibition due to the exposure to different temperatures in darkness, and after temperature-light treatment were studied. The photochemical activity of PSII was measured after the incubation of the samples in a solution containing 50% glycerol (volume) or 1 M sucrose for 5 minutes in the dark at a certain temperature or under high light intensity at the same temperature. The photochemical activity
of the PSII complex was found to be partially preserved in samples incubated in a glycerincontaining solution, at high temperatures, in both dark and light. The addition of sucrose to the solution resulted in a higher degree of protection of the photochemical activity of PSII. Keywords: Photosystem II, temperature, light, inhibition
