There is a wide range of potential applications to characterize plants where chlorophyll fluorescence technique and gas-exchange analysis can be employed. In particular, chlorophyll fluorescence analysis has a large potential for high throughput phenotyping. 

Screening for abiotic stress tolerance in plant breeding

Improved stress tolerance is a major goal in plant breeding. The early identification of stress tolerant genotypes within a large set of plants is often a very difficult task. Using chlorophyll fluorescence analysis, genotypes tolerant to low temperature can be efficiently discriminated by their quantum efficiency of photosystem II. Drought tolerance is another very important trait for crops, which can be quantified via photosynthesis or by determination of transpiration.

Testing of agro-chemicals

Many chemicals affect plants. The goal is to identify chemicals that negatively affect weeds. This phytotoxicity can be rapidly detected by non-invasive estimations of photosynthetic activity. On the other side, there is an increasing demand to identify beneficial effects of agro-chemicals on crop plants, for example, agro-chemicals that have a positive effect on the stress tolerance of the crop. Again, chlorophyll fluorescence analysis may be the best suited method to detect these effects.
