      abstract     = {The photosynthesis of various species or even a single
                      plant varies dramatically in time and space, creating great
                      spatial heterogeneity within a plant canopy. Continuous and
                      spatially explicit monitoring is, therefore, required to
                      assess the dynamic response of plant photosynthesis to the
                      changing environment. This is a very challenging task when
                      using the existing portable field instrumentation. This
                      paper reports on the application of a technique,
                      laser-induced fluorescence transient (LIFT), developed for
                      ground remote measurement of photosynthetic efficiency at a
                      distance of up to 50 m. The LIFT technique was used to
                      monitor the seasonal dynamics of selected leaf groups within
                      inaccessible canopies of deciduous and evergreen tree
                      species. Electron transport rates computed from LIFT
                      measurements varied over the growth period between the
                      different species studied. The LIFT canopy data and
                      light-use efficiency measured under field conditions
                      correlated reasonably well with the single-leaf pulse
                      amplitude-modulated measurements of broadleaf species, but
                      differed significantly in the case of conifer tree species.
                      The LIFT method has proven to be applicable for a remote
                      sensing assessment of photosynthetic parameters on a diurnal
                      and seasonal scale; further investigation is, however,
                      needed to evaluate the influence of complex heterogeneous
                      canopy structures on LIFT-measured chlorophyll fluorescence
                      parameters.},
