Applications 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.
