Scanalyzer System
discovers THE ONE
which is relevant…
+3%
For example, THE plant with 3% increase in value is worth
$50m if it obtains 10% market penetration and released 2 years earlier
Automatic screening 10x more efficient than human screening

non invasive and valuable information about plant roots in substrate?
• 3D root morphologie
• 3D root dynamics
• 3D root activity (water distribution)
• etc...

Problems:
• artefacts (debris) in substrate hide roots (H2O + Fe)
• low contrast between roots and background
• correct setting of NMR has to be researched
