Optical Marker Developed for Plant Stress
FORCE-A has developed Dualex Scientific, a chlorophyll-meter that also measures flavonols.
FORCE-A has developed Dualex Scientific, a chlorophyll-meter that also measures flavonols.
This leaf-clip, the result of 15 years of development by French research institute CNRS, allows to perform real-time and non-destructive measurements. Its internal GPS is used for the geolocalization of the blocks.
This optical sensor offers various applications, specifically used in ecophysiology:
This optical sensor offers various applications, specifically used in ecophysiology:
- Detection of nitrogen deficiency (especially nitrogen) and input management.
- Quality control (wheat protein).
- Variety selection and phenotyping (low input seedlings) in major and specialised crops.
- Assessment of thermal stress resistance, UV, light and low temperatures.
- Test of plant natural protection (natural protection stimulation,elicitors, etc.).
- Polyphenol antioxydant quantification of leaf and fruit epidermis.
- Foliar development and plant senescence monitoring.
Basically, Dualex Scientific is a stress marker is used to assess plant health and development.
The indices, calculated by the system, are:
The indices, calculated by the system, are:
- SFR (Simple Fluorescence Ratio), the chlorophyll content of the sample.
- FLAV, the content of flavonols.
- NBI (Nitrogen Balance Index), ratio SFR/FLAV, marker of nitrogen deficiency and protein rate.
