P. Ilik et al., CHLOROPHYLL FLUORESCENCE CHANGES AT HIGH-TEMPERATURES INDUCED BY LINEAR HEATING OF GREENING BARLEY LEAVES, Photosynthesis research, 44(3), 1995, pp. 271-275
A relative decrease of the high temperature part (above 60 degrees C)
of the chlorophyll. fluorescence temperature curve during 3 h to 10 h
greening period of barley (Hordeum vulgare L.) leaves was found to be
concomitant to a decrease of Chl a/b ratio and to a gradual increase o
f LHCP/core ratio found by electrophoresis and the ratio of granal to
total length of thylakoid membranes. It is suggested that the high tem
perature part of the fluorescence temperature curve depends inversely
on the relative amount of LHC II in thylakoid membranes.
