An increasing role in plant phytodiagnostics becomes to play different spectrometric techniques used as a part of
remote sensing applications. The radiation behavior of land covers and the spectral response to changing conditions
lies at the root of these studies. The visible and near infrared (400 - 900 nm) measurements have proved abilities in
vegetation monitoring. The reason is that this wavelength range reveals significant sensitivity to plant biophysical
properties. The information is carried by the specific vegetation spectral characteristics which depend on such plant
parameters as chlorophyll content, biomass amount, leaf area, etc. These parameters are associated with plant development
and stress factors being closely related to vegetation physiological state. In our study, multispectral data of
reflected, transmitted and emitted irradiance have been used to show the possibility for plant chlorophyll assessment.
Different methods such as vegetation indices, red edge analysis and fluorescence spectra have been applied
and compared.
