Chlorophyll fluorescence can measure most types of plant stress. Chlorophyll fluorescence can be used as a proxy of plant stress because environmental stresses, e.g. extremes of temperature, light and water availability, can reduce the ability of a plant to metabolise normally. See more 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 … 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 … See more PSII yield as a measure of photosynthesis Chlorophyll fluorescence appears to be a measure of photosynthesis, but this is an over-simplification. Fluorescence can measure the efficiency of PSII photochemistry, which can be used to estimate the rate of … See more LIF sensors Techniques based on the Kautsky effect do not exhaust the variety of detection and evaluation methods based on the chlorophyll … See more Usually the initial measurement is the minimal level of fluorescence, $${\displaystyle \,F_{0}}$$. This is the fluorescence in the absence of photosynthetic light. See more The development of fluorometers allowed chlorophyll fluorescence analysis to become a common method in plant research. Chlorophyll fluorescence analysis has been … See more • Integrated fluorometer for gas exchange and chlorophyll fluorescence of leaves • Non-photochemical quenching See more Webthe fluorometer can obtain the same data from samples of 500 ml or less. Sometimes the large volumes required for spectrophotometric determination are nearly impossible to filter because of clogging problems. The spectrophotometric determination of chlorophyll involves filtration, disruption of the cells, and extraction of cyclop junctions
