Temporal influence of changing low/high temperature-irradiation environmental conditions,
fluctuating in seven diurnal cycles (A), on two plant species Persea americana (B) and Ficus sp.
(C), expressed by fluorescence parameters measured remotely with the ground-based laser-induced
fluorescence transient (LIFT) fluorometer (D). (T, air temperature; PPFD, photosynthetically active
photon flux density; Fs, LIFT measured steady-state fluorescence; Fm′, LIFT measured maximum
fluorescence of light-adapted leaves; ΔF=Fm′−1 ∼ actual quantum yield (efficiency), where ΔF=Fm′−F
s).
