Abstract

A description is given of time-resolved measurements of the laser-induced chlorophyll fluorescence emission of vegetation detected by two different techniques. Fluorescence decay time measurements using single-photon counting and picosecond laser pulse excitation have been used to analyze the fluorescence heterogeneity of leaves from higher plants. The fluorescence is described by lifetimes of 10-40 ps, 80--150 ps, 400-500 ps, and 700-1000 ps. When the reaction center is closed by application of DCMU, the lifetimes of the slowest components increase by a factor of about 3. Another possible means of monitoring the fluorescence after picosecond excitation is a streak camera detection system. Measurements performed on the slow decay component of stressed and unstressed plants are presented.
