The thermoluminescence (TL) parameters in the intact leaves and the thylakoids isolated from leaves of NaCl treated seedlings showed different patterns of change. NaCl treatment brings about a destabilization of Q A and Q B , leading to a decrease in Q and B bands in the leaves. However, the Q and B band intensity of isolated thylakoids increased in NaCl‐treated seedlings. The differences in the TL intensities are described as the action of NaCl on the density of quinones per unit leaf area and on chlorophyll units in isolated thylakoids.
