Chlorophyll fluorescence and stability of chlorophyll-protein complexes (CPC) was followed during gradual heating of barley leaves. At 40–50 C, when the first peak in the chlorophyll fluorescence temperature curve (FTC) was reached reflecting decrease in PSII photochemistry, the PSII core (CCII) dimers began to dissociate into monomers. Further changes in CPCs appeared at 57–60 C, when FTC increases to its second maximum. Photosystem I (PSI) cores (CCI) partially dissociated from light-harvesting complexes of PSI (LHCI) and formed aggregates
