WebAug 3, 2013 · As chlorophyll fluorescence is a measure of re-emitted light (in the red wavebands) from PSII, naturally this means that any ambient light can interfere with the measurement of fluorescence and thus many early systems had to be used in darkness and/or highly controlled light environments. WebThe PAM-2500 chlorophyll fluorometer is an extremely compact and powerful measuring system. All optical and electronic components are located in a 23 cm x 10.5 cm x 10.5 cm housing. Different from previous portable PAM fluorometers, high-performance LEDs are employed for saturation pulses permitting quasi-rectangular light intensity changes.

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.
