Effects of different R/B ratios on the fitting parameters of photosynthetic light response curve, including A_max, R_d and α.

R/B ratio	B	R/B = 1	R/B = 4	R/B = 8	R/B = 12	R
A_max (μmol CO₂⋅m⁻²⋅s⁻¹)	27.6^b	31.3^a	29.7^ab	23.8^c	20.7^d	18.0^e
R_d (μmol CO₂⋅m⁻²⋅s⁻¹)	2.3^c	2.7^b	2.8^b	3.3^a	2.7^b	2.6^bc
α (μmol photons⋅m⁻²⋅s⁻¹)	0.082^b	0.086^ab	0.114^ab	0.108^ab	0.117^a	0.084^b

Different letters indicate significant difference using the Duncan’s Multiple Range Test (p < 0.05; n = 4).
