LOW AND HIGH-TEMPERATURE DEPENDENCE OF MINIMUM F-O AND MAXIMUM F-M CHLOROPHYLL FLUORESCENCE IN-VIVO

The aim of this paper is to give a global insight into the behaviour o f F-0 and F-M in a wide temperature range from -100 degrees C to 75 de grees C. We show that the F-0 increases upon linear freezing, similarl y to the widely published increase of the F-0 upon linear heating. In contrast to this the F-M decreases upon linear heating in the whole te mperature range from -100 degrees C to 75 degrees C. A comparison of l ow and high temperature induced increase of the F-0 is presented. (C) 1998 Elsevier Science B.V.
