A wide range of choices for the quantitative, non-destructive analysis of different crops or model plants in field conditions.
Field phenotyping is the classical strategy to assess qualitatively and quantitatively agronomical important traits for field-grown plants. Many assessment methods are based on direct visual assessment or the manual use of portable measurement units. Considering the increasing amount of non-destructive, image-based measurement systems that have become available in the last few years, there is a strong tendency to use these non-destructive methods in the field as well as in more controlled environments like greenhouses and growth rooms.
Compared to greenhouse and growth room phenotyping, outdoor measurement systems have to accommodate the high temporal variability of environmental growth conditions in the field. Furthermore, field conditions challenge durability of the measurement systems which must also have the operating range to cope with the high dynamics of measurement conditions- especially the variability of light quality and quantity affecting any image-based measurement system
