Laser spectrofluorometry of agronomic plants in vivo

摘要

Laser spectrofluorometry of agronomic plants in vivo at the single leaf level permits to investigate the effects of the growth phase, part, nodal position and age of the leaf, agrochemical treatment, external physical factors and plant diseases on the chlorophyll fluorescence. Such a spectroscopic approach can give the possibility to monitoring the development and health status of agronomic plants during ontogenesis and under different stresses. The relevant spectral wavelengths and criteria which correlate with status of the plant were determined.
