Comparison of recoveries of net photosynthetic rates (P _n) of 1-h and 25-h restoration after exposure to high temperature (45 °C for 4 h) stress

Type	Pn (μmol/(m2∙s))			Recovery of Pn (%)
	Pre-exposure	1 h after exposure	25 h after exposure	1 h after exposure	25 h after exposure
Wild	5.34±0.37	1.87±0.1	4.02±0.38	35.0±1.0	75.2±12.8
