[EPR study of electron transport in higher plant photosynthetic systems. II. Effect of temperature on the kinetics of photoinduced oxidation-reduction transformations of P700].

A sharp fall of ESR signal I is observed at temperature decrease while switching on light of 600 nm on the background of light of 707 nm; kinetics of the initiation of the signal under the illumination of light of 707 nm gets more complicated; the induction phase induced by previous illumination with the light of 600 nm increases.
