Relationship of total intercepted photons (A), quantum yield of photosystem II (Φ_PSII ) (B), and net CO₂ assimilation rate (P_net ) (C) with total dry weight (DW) under the interactive effect between light spectra and temperature under two light intensities [150 and 300 μmol m^-2 s^-1 in total photon flux density (TPFD; 400-800 nm)]. The two light spectra are denoted based on the percentage of far-red photons (FR; 700-800 nm) in TPFD, i.e., 0 and 20% FR light. The three temperatures were 20, 24, and 28°C.
