... correspond to the end of the J I phase [8,28,29]. It is likely that the emergence of a peak for I in the FI curves depends on the relative amplitude and rate constant of the J Iphase compared to the ... terms of the origin of each kinetic phase.AbbreviationsAO J , A J Iand AI P , amplitude of O J, J I and I P phases, respectively; Chl, chlorophyll; DCMU, 3-( 3,4-dichlorophenyl )-1 ,1-dimethylurea;dPQ, ... traces. In the presentstudy, we used this approach, as proposed by Pospisil& Dau [16,20], to evaluate the contributions and kinet-ics of the three main components of the FI traces.Deconvolution...
