Abstract

Fluorescence sensing systems for the remote assessment of vegetative parameters are currently being developed and tested for use from a variety of sensing platforms. Multi-spectral fluorescence imaging techniques are being applied to assess plant responses to changes in its growth environment. Fluorescence abaxial vs. adaxial spatial patterns of band emissions are discussed with respect to individual leaves excised from a field corn canopy supplied with four levels of nitrogen fertilization. Fluorescence emissions for adaxial leaf surfaces were found significantly lower in intensity and specific emission bands and band ratios were found sensitive to N fertilization level.
