The character of structural changes in thylakoid membranes caused by temperature variation was investigated. Experiments were performed on maize leaf segments in vivo and in a closed temperature cycle 24-50-24 degrees C. Two biophysical methods were used for detection: luminescence and EPR. Arrhenius plots of delayed fluorescence (DF) versus reciprocal temperature revealed two break points, T1 ...
