The Origin of Chloroplast Fluorescence Decay Kinetics: Picosecond Fluorescence of Mutants and Sub-chloroplast Particles of Chlamydomonas reinhardii and Barley

Abstract

The form of the fluorescence decay function from the light harvesting system of photosynthetic organisms has now been determined quite accurately by low-intensity synchronously pumped dye laser excitation coupled with single photon counting detection. Several groups [1,2,3] have found it necessary to use a sum of three exponential decay components (eq. 1) to fit the decay curves of both green plants and algae.</jats:p
