WebJan 15, 2024 · At room temperature, Chl a fluorescence in the 600-800 nm range is mainly emitted by PSII pigments. The fluorescence spectrum presents a dominant maximum at ~690 nm and a smaller broad peak at... Chlorophyll fluorescence is light re-emitted by chlorophyll molecules during return from excited to non-excited states. It is used as an indicator of photosynthetic energy conversion in plants, algae and bacteria. Excited chlorophyll dissipates the absorbed light energy by driving photosynthesis (photochemical … See more Upon illumination of a dark-adapted leaf, there is a rapid rise in fluorescence from Photosystem II (PSII), followed by a slow decline. First observed by Kautsky et al., 1932, this is called the Kautsky Effect. This variable rise in … See more Usually the initial measurement is the minimal level of fluorescence, $${\displaystyle \,F_{0}}$$. This is the fluorescence in the … See more The development of fluorometers allowed chlorophyll fluorescence analysis to become a common method in plant research.
