Continuous change of fluorescnece intensity with the maximum of 735 mu (F735) has been investigated in higher plants leaves at emperature decrease up to that of liquid nitrogen. F 735 remains approximately constant at temperature decrease up to -60degrees C. In temperature range -60divided by -80 degrees C the intensity F 735 increases. This increase proceeds up to-160 degreesC. Such temperature relationship is not changed with the addition of Mg+ ions. Speculations are presented concerning the nature of such relationships.
