Short Name:
 Fv_Fm
Short Description:
 Fv to Fm ratio
Official Name:
 Fv_Fm
No Data Value:
 nd
Description:
 

The difference between maximum fluorescence and minimum fluorescence is Fv, or variable fluorescence. Fv/Fm is a normalized ratio created by dividing variable fluorescence by maximum fluorescence.

Description: 
The maximum Quantum yield. A measure of the Photosystem II efficiency. In a dark-adapted sample this is equivalent to Fv/Fm. In a light-adapted sample it is equivalent to Fv'/Fm'.
