Temperature Dependence of Chlorophyll a Fluorescence in Relation to the Physical Phase of Membrane Lipids Algae and Higher Plants

Abstract

The temperature dependence of the yield of chlorophyll a fluorescence was measured at room temperatures in living algal cells and higher plant chloroplasts. 3-(3′,4′-Dichlorophenyl)-1, 1-dimethylurea was added to the samples during the measurements in order to eliminate the influence of photosynthetic photochemical reactions on the fluorescence yield.
