These protocols are useful in measuring many types of plant stress. In: Papageorgiou, G. This is done to measure leaf transpirationand to correct CO 2 measurements. Springer, Dordrecht the Netherlandspp. Categories : Light reactions Photosynthesis.
The dark-adapted photochemistry of photosystem II itself (measured as Fv/Fm, where Fv ¼ Fm А F0) remained unaffected until a very late stage of damage to the.
Returning the leaf to a fully dark-adapted state (Fv/Fm value . resolution microscope chlorophyll fluorescence imaging system (unpublished. (B) A typical fluorescence trace made on dark-adapted leaf material .

They typically also use fewer measurements. Vredenberg, W.
This is due to; 1. Chlorophyll fluorometers are, for the most part, less expensive tools than photosynthesis systems, they also have a faster measurement time and tend to be more portable. Determining when to apply additional N
