title: Effects of UV-B radiation on laser-induced fluorescence spectra in crop leaves.
abstract: Influence of ultraviolet-B (UV-B) exerted on the peanut leaves was examined by using the laser-induced fluorescence (LIF) method. Linear relation was seen in vitality decrease of peanut leaves and UV-B fluence. In addition, it has been understood to be able to evaluate the vitality decrease of leaves by measuring the change in a specific fluorescence peak ratio. It is thought that an early detection and an evaluation of UV-B stress may be possible by applying this method to remote-sensing.
