Improving photosynthetic efficiency by modulating non-photochemical quenching
Trends in Plant Science, 2023High light exposure rapidly activates non-photochemical quenching (NPQ), protecting plants from photooxidative damage. Contrarily, its relaxation upon transition to normal light occurs quite slowly, limiting photosynthetic efficiency. De Souza et al.

The role of photochemical quenching and antioxidants in photoprotection of Deschampsia antarctica
Functional Plant Biology, 2004Deschampsia antarctica Desv. (Poaceae) is the only grass that grows in the maritime Antarctic. Constant low temperatures and episodes of high light are typical conditions during the growing season at this latitude. These factors enhance the formation of active oxygen species and may cause photoinhibition.

Excimer and non-photochemical quenching in LHCII
The Journal of Chemical PhysicsThe light-harvesting complex of photosystem II (LHCII) plays the dual roles of photosynthetic energy capture and dissipation, where the excitation energy in excess is dissipated safely via non-photochemical quenching (NPQ) to avoid photodamage. Chlorophyll excimer was recently reported to be an intrinsic photophysical intermediate in LHCII, which may ...

Chlorophyll fluorescence quenching induced by low concentrations of m-dinitrobenzene (DNB) is investigated. In intact spinach chloroplasts DNB causes photochemical and non-photochemical quenching. The two forms of quenching are distinguished by applying the saturation pulse method with a new type of modulation fluorometer.

A METHOD OF TREATING PHOTOCHEMICAL TRIPLET QUENCHING DATA
Photochemistry and Photobiology, 1969Abstract— A modified Stern‐Volmer plot method is proposed for treatment of quantum yield data where both reactive photoexcited singlet and triplet states are present in solution. The method may be applied when the reactions occurring are zeroth order in ground state photochemical substrate and allows the separation of singlet and triplet state ...

The kinetics of non-photochemical quenching (NPQ) of chlorophyll fluorescence was studied in pea leaves at different temperatures between 5 and 25 degrees C and during rapid jumps of the leaf temperature. At 5 degrees C, NPQ relaxed very slowly in the dark and was sustained for up to 30 min.

PsbS-Dependent Non-Photochemical Quenching
2014Much of the research on the thermal dissipation of excess absorbed light, measured as non-photochemical quenching (NPQ) of chlorophyll fluorescence, has been focused on a major, rapidly induced and rapidly reversible component of fluorescence quenching termed energy-dependent quenching, feedback de-excitation, or qE.
