Abstract
Measurements of laser-induced chlorophyll fluorescence of living leave s were compared to ecophysiological parameters, both in near and far f ield conditions. Near field measurements were carried out with a two-w ave-length portable fluorometer, both in the laboratory and in the fie ld. Results show significant changes of the 690 nm and 730 nm chloroph yll fluorescence bands in different environmental conditions. Water st ress and carboxylation limitations also affect the fluorescence spectr a. Far field measurements from a ground-operated fluorescence LI-DAR s ystem confirm those results. The F690/F730 fluorescence ratio is then demonstrated as a good index for vegetation remote sensing.
