Effects of temperature on Chlorophyll Fluorescence Parameters of Fragaria×ananassa Duch. cv. Toyonoka
The experiments were made with Fragaria×ananassa Duch. cv. Toyonoka. It was studied that the effects of temperature on chlorophyll fluorescence of Fragaria×ananassa Duch. cv. Toyonoka by PAM-2100 in normal light environment. The activity of PS II and the parameter of chlorophyll fluorescence in leaves such as conversion efficiency of primary light energy (Fv/Fm) of PS II, the photochemical quenching coefficient (qP), and the quantum yield of PS II electron transport (Yield) were decreased respectively when temperature is 5℃, 10℃ and 25 ℃. In all, when temperature is 15℃ and 20℃, the value of Fv/Fm, yield, qP were higher. It showed that in normal light environment, the temperature from 15℃ to 20℃ is benefit to the photosynthesis of Fragaria×ananassa Duch. cv. Toyonoka.
