D. Lazar et al., MATHEMATICAL-MODELING OF CHANGES IN CHLOROPHYLL FLUORESCENCE INDUCTION CAUSED BY HERBICIDES, Pesticide biochemistry and physiology, 57(3), 1997, pp. 200-210
Chlorophyll fluorescence induction curves of cereal leaves measured du
ring herbicide action were simulated by a mathematical model based on
description of electron transfer through photosystem II to a plastoqui
none pool. To obtain results comparable with experimental measurements
, we considered three kinds of photosystem II centers: Q(B)-reducing,
Q(B)-nonreducing, and inactive centers. We compared the parameters cal
culated using mathematical simulations with experimental parameters ob
tained with barley and wheat leaves treated with triazine-and urea-typ
e herbicides. A good agreement between simulated and experimental para
meters was found. (C) 1997 Academic Press.
