initiating this project and provided many helpful comments.
We are very grateful to Larry Giles and Todd Tobeck for
valuable help in performing the experiments. RP was

abstract = {Chlorophyll fluorescence measurements have been widely
applied to quantify the photosynthetic efficiency of plants
non-destructively. The most commonly used pulse amplitude
modulated (PAM) technique provides a saturating light pulse,
which is not practical at the canopy scale. We report here
on a recently developed technique, laser induced
fluorescence transient (LIFT), which is capable of remotely
measuring the photosynthetic efficiency of selected leaves
at a distance of up to 50 m. The LIFT approach correlated
well with gas exchange measurements under laboratory
conditions and was tested in a field experiment monitoring
the combined effect of low temperatures and high light
intensity on a variety of plants during the early winter in
California. We observed a reduction in maximum and effective
quantum yield in electron transport for Capsicum annuum L.,
Lycopersicon esculentum L. and Persea americana Mill. as the
temperatures fell, while a grass community was not affected
by combined low temperature and high light stress. The
ability to make continuous, automatic and remote
measurements of the photosynthetic efficiency of leaves with
the LIFT system provides a new approach for studying and
monitoring of stress effects on the canopy scale.},
