abstract = {Many laboratory studies investigating chlorophyll
fluorescence (F) of plants have provided sufficient evidence
of the functional link between dynamic changes in
photosynthetic activity and F emissions. Far fewer studies,
however, have been devoted to detailed analysis of F
emission under steady-state conditions, which may be
amenable to measurement by passive spectroradiometers
onboard airborne or satellite missions. Here, we provide a
random-effects meta-analysis of studies using both passively
(sun-induced) and actively (e.g. laser-induced) measured
steady-state F for detecting stress reactions in terrestrial
vegetation. Specifically, we review behaviour of F in red
and far-red wavelengths, and also the red to far-red F
ratio, for plants physiologically stressed by water deficit,
temperature extremes, and nitrogen insufficiency. Results
suggest that water stress is, in general, associated with a
decline in red and far-red F signal intensity measured at
both leaf and canopy levels, whereas the red to far-red F
ratio displays an inconsistent behaviour. Chilling, for
which only studies with active measurements at the leaf
level are available, significantly increased red and far-red
F, whereas heat stress produced a less convincing decrease
in both F emissions, notably in canopies measured passively.
The clearest indicator of temperature stress was the F
ratio, which declined significantly and consistently. The F
ratio was also the strongest indicator of nitrogen
deficiency, revealing a nearly uniformly increasing pattern
driven by predominantly declining far-red F. Although
significant knowledge gaps were encountered for certain
scales and F measurement techniques, the analyses indicate
that future airborne or space-borne acquisitions of both red
and far-red F signals would be beneficial for timely
detection of plant stress events.},
