3D imaging of sugar beet in natural soil with co-registered MRI/PET


 

3D imaging of sugar beet in natural soil with co-registered MRI/PETMRI/PET von Zuckerrüben

Biotic and abiotic stresses may damage plant parts above- and belowground and thereby reduce the sugar beet yield. Since the parts of the sugar beet plants that are relevant for yield are located belowground their current status cannot be assessed by the naked eye. Non-invasive imaging techniques for monitoring the beet during the whole vegetation period may therefore produce important data about the development of the plant. Magnetic resonance imaging (MRI), known from medical applications, enables investigation of the status and development of three-dimensional beet and roots architecture and biomass. The combination with positron emission tomography (PET) further allows to follow sap flows within the plant body.

The application of these methods enables phenotyping of the belowground organs of the sugar beet plants which is used within the framework of the subproject ZA3 of CROP.SENSe.net to gather important information about the current status of the plants for the purposes of plant breeding. Specifically the impact of abiotic stress on different sugar beet genotypes (seeds are deployed from partners within CROP.SENSe.net) shall be investigated.

A continuous analysis of the canopies of sugar beet plants is of equal importance, since especially biotic stresses like pathogen infection may have a strong negative impact on the yield. Development of an appropriate sensory system is addressed in a parallel project (CROP.SENSe.net subproject ZS1).
