[2 types of reduction of P700+ reaction centers in the leaves of green plants].
It is shown that in the leaves of Hibiscous sp. the ESR signal I rises under weak far red light after its partial inhibition with a short white flash is slower than after adaptation to 710 nm light and short dark exposition. It is suggested that this divergence in the ESR kinetics is due to the fact that only part of reduced intermediates generated by the photosystem 2 under flash is readily available to P700+, whereas other reducing reagents slowly react with the photosystem 1 reaction centres.
