The ratio between ΦPSII from fluores­cence and ΦCO2 from gas exchange is a measure of how efficiently a plant uses absorbed light energy to assimilate CO2.

With our portable photosynthesis system, LI-6800F, which combines Leaf Gas Exchange and Fluorescence measurements, we can measure chlorophyll a fluorescence and gas exchange simultaneously. This allows for a more com­plete picture of the coupled energy-producing and energy-consuming reactions of photosyn­thesis.

Overall, this testing service provides you with the following:
