A transient in chlorophyll fluorescence, which is associated with a transient in 9-aminoacridine fluorescence and a perturbation in the rate of oxygen evolution, has been observed in intact spinach chloroplasts. The results indicate that changes in the redox state of Q are, at least partially, respo

Using the chlorophyll fluorescence induction and oxygen ew)lution measurements we investigated the influence of alteration of the fluidity of pea lhylakoid membranes on PSII activity and heterogeneity. The treatment of thylakoid membranes with cholesterol, leading to a decrease of membrane fluidity,
## Abstract The site of action of nitrite on PS II was investigated by measuring the TL profile of nitriteβtreated spinach thylakoid membranes. Three bands were observed in control, which were identified as the Q band (7Β°C), the B band (24Β°C) and the C band (57Β°C). In the presence of 20 mmol/L nitr
The major phytotoxic compounds (encecalin, euparin and demethylencecalin) isolated from Helianthella quinquenervis (Hook) A Gray (Asteraceae) were evaluated on di β erent photosynthetic activities in chloroplasts isolated from spinach leaves.

The influence of nitrite and nitrate on chlorophyll fluorescence, a very sensitive indicator for the redox state of the primary accepter of photosystem IX of photosynthesis, was studied in green algae (several species of Chlorella, and Ankistrodesmu8 braunii). In phosphate solution under an atmosphe
High energy state quenching of chlorophyll fluorescence (qE) is inhibited by low concentrations of the inhibitor antimycin A in intact and osmotically shocked chloroplasts isolated from spinach and pea plants. This inhibition is independent of any effect upon ApH (as measured by 9-aminoacridine fluo
