FluorCamPortable photosynthetic chlorophyll fluorescence imaging system

The photosynthetic parameters such as photosynthetic rate, transpiration rate, and stomatal conductance of plants can comprehensively measure the intensity and ability of plant photosynthesis; Chlorophyll fluorescence not only reflects the primary reaction processes of photosynthesis, such as light energy absorption, excitation energy transfer, and photochemical reactions, but also relates to electron transfer, proton gradient establishment, ATP synthesis, and CO₂Fixed and related processes. The combined measurement of both is indispensable in the study of plant photosynthetic physiology. The FluorCam portable photosynthetic chlorophyll fluorescence imaging system can be combined with the internationally renowned photosynthetic instrument LCpro to measure both photosynthesis and plant fluorescence. It can also work independently in the laboratory or field.
