Abstract
The laser-induced fluorescence (LIF) of green plants was evaluated as a means to detect the growth and to determine species differentiation. Leaves of an evergreen tree (two sorts), a deciduous tree (three sorts), a needle-leaf tree (two sorts) and a herbaceous plant (two sorts) were used as representatives in these studies. The fluorescence spectra of several plant pigments were excited with a nitrogen laser emitting at 337 nm. These plant spcies exhibited fluorescence spectra, their spectra were in visible region from 400 nm to 684 nm. It was found that each spcies of in vivo plant has its characteristic structure of the emission spectrum. The special feature of their plant species also became clear.
