RC/ ABS. Light energy absorbed per unit reaction centerꎻ φP O . The probability of PS Ⅱ photoexcited electrons transfer to PS Ⅱ secondary
electron acceptor Q A ꎻ ψE O . The probability that the electrons captured by PS Ⅱtransfer from Q A to PQꎻ δR O . Efficiency of electron transfer
from PQH 2 to the final acceptor of PSⅠ. The redꎬ blue and green colors represent Q. liaotungensisꎬ Q. coccinea and Q. rubraꎬ respectively. This
figure shows the differences of kinetic parameters in rapid chlorophyll fluorescence induction of three Quercus species under different temperature
conditions (25ꎬ 35ꎬ and 45 ℃)ꎬ and the parameter values gradually increase from inside to outside. Each indicator in the figure is standardized
by [0ꎬ 1]ꎬ and the number in the figure indicates the scale of the coordinate axis.
